Kari Poppinz

Hi, I'm Kari Mahady, a Certified Pediatric Sleep Consultant, Newborn Care Specialist, and career nanny with over 24 years of experience supporting children and families.

My journey into sleep consulting came after spending decades helping families navigate everything from newborn sleepless nights to toddler bedtime battles. I saw firsthand how profoundly sleep affects a family's well-being and how many parents feel overwhelmed, exhausted, and unsure where to turn. I wanted to provide families with the guidance, support, and confidence they need to create healthy sleep habits that last.

My approach is personalized, practical, and family-centered. I don't believe there is one right way to help a child sleep. Every baby, child, and family is unique, so I create customized plans based on your child's temperament, developmental stage, feeding needs, and your parenting goals. Whether you prefer a gentle, hands-on approach or a more structured method, I work alongside you to find a solution that feels right for your family.

I specialize in helping newborns, infants, toddlers, and preschoolers overcome challenges such as frequent night wakings, short naps, bedtime struggles, early morning wake-ups, sleep regressions, and transitions from co-sleeping or parental assistance to independent sleep.

The families I love working with most are those who are exhausted, overwhelmed, and ready for change but still want to feel supported throughout the process. My goal is not only to help your child sleep better but to help you feel confident, empowered, and rested again.

After all, every family deserves a little sleep magic.
My philosophy

There is no one-size-fits-all approach to sleep. My goal is to create a personalized plan that helps your child sleep better while honoring your family's parenting style and comfort level.

I recently worked with a family of 9-month-old twins who were referred to me by a pediatrician I partner with. The twins were waking three times each night to feed and were only taking 30-minute naps. Before beginning formal sleep training, we focused on improving daytime calories and optimizing their feeding and sleep schedule. To everyone's surprise, both babies slept through the night on the very first night and continued sleeping through the night consistently. Their naps also lengthened and became much more predictable, demonstrating how powerful the right schedule and feeding foundation can be.
Here's a polished version that highlights both the challenge and the outcome:

I worked with a 2.5-year-old who had recently transitioned to a big kid bed and was struggling with both bedtime and overnight sleep. It was taking nearly two hours for him to fall asleep at bedtime, and he was waking most nights and staying awake for another one to two hours. The sleep challenges had become so exhausting that the family had begun using screens in the middle of the night to help him settle back to sleep.

After making some adjustments to his daytime schedule and nap timing, we implemented a personalized sleep training plan focused on independent sleep skills and consistent boundaries. Within one week, bedtime had transformed from a two-hour struggle into a simple goodnight kiss and walk out. He was falling asleep independently and sleeping through the night, giving the entire family the rest they desperately needed.

Kari is awesome! She gave us a full plan for bed time, naps, wake windows, and feedings to to help our 5-month old get into a solid sleep routine, fall asleep independently, and sleep so much better at night. She was always available for support and to answer questions and was very thoughtful and thorough in all her responses. We are so grateful to have worked with her!

We worked with Kari for our second kiddo, who was 5 months at the time. We had a good understanding of sleep training as we did it without a trainer for our first. However we had just gotten back from international travel and our little one's schedule was all over the place, we had a short timeline before we returned to work, and we were so tired! Within ten days, Kari had our little one going from 25 minute naps to 90 minute naps and from waking 4+ times in the night to waking once for a quick feed. She was extremely timely in her responses and worked to problem solve each new hurdle! We are grateful for her help and SO GRATEFUL for the sleep!!

Kari helped us get our 4 month old son to sleep through the night. She helped us focus on increasing his intake during the day, and come up with a method that we felt comfortable using when he cried during the night. She was also great at checking in frequently and very responsive.

We worked with Kari to help our 4 month old transition into his crib, and the results have been amazing -he's now sleeping through the night! She also supported us with a plan for our 4 year old as she moved into her big kid bed. She was supportive, responsive and encouraging throughout the entire process. She checked in often, kept us accountable, and made sure we felt confident every step of the way. Her guidance made such a difference for our whole family. We're so grateful for her expertise and highly recommend her to anyone needing sleep support!

Kari helped us get our son sleeping 11 hours straight at just 4.5 months old! She created a customized plan for his eating, naps, and bedtime, and was always checking in and adjusting as needed. When we were struggling with naps, she even came over for half a day to walk us through things in person and gave us amazing tips. We highly recommend Kari and her sleep training expertise - she truly made a huge difference for our family and our little one's sleep!

Working with Kari has been such a supportive and transformative experience for our family. From the very beginning, she was not only kind and compassionate but also incredibly informative. The way she explained things made us feel reassured and confident, giving us clear and practical steps that were tailored to Emmi's needs. Kari was patient, thorough, and always available to answer questions, no matter how big or small. She provided us with tools, knowledge, and encouragement that truly made a difference. Her guidance helped us better understand Emmi's sleep patterns and how to support healthy habits, and we immediately noticed positive changes. Most importantly, Kari made us feel cared for throughout the entire process. Her genuine dedication and empathy made what could have been a stressful time feel manageable and hopeful. We are so grateful for her expertise and support—it has been such a blessing to have her by our side. I would wholeheartedly recommend Kari to any family looking for someone who is supportive, knowledgeable, and truly invested in helping children and parents thrive.

I can't express enough how grateful we are for the sleep training help we received. Kari was incredibly patient, supportive, and knowledgeable throughout the entire process. We were struggling with consistent naps and our daughter was waking up several times at night at six months old. She used the check-in and console method, which allowed us to feel confident in letting our daughter learn to self-soothe while still offering comfort when needed. From the start, Kari took the time to understand our daughter's unique needs, and her gentle yet firm approach made all the difference. We saw immediate improvements in our daughter's ability to fall asleep on her own and stay asleep longer. The method, while tough at times, was explained thoroughly, and we felt empowered rather than overwhelmed. What I appreciated most was Kari's balance of compassion and consistency. She was always available to answer questions and offered reassurance during moments of doubt. Thanks to her guidance, naps and nighttime are no longer a stressful time for our family, and we're all sleeping better. At 16 months old, our daughter takes two-two hour naps during the day and sleeps twelve hours through the night. I highly recommend Kari to any parent looking for professional, kind, and effective sleep training support!

I was truly at my breaking point when we reached out. My 11 month old daughter was waking every 45 minutes for 10 hours straight and I was completely exhausted. She would only settle for me and my husband couldn't help until the morning. He started waking up at 6 AM before work just so I could get a couple hours of sleep before being a stay at home mom all day. We were both running on empty. We were scared to sleep train because she's such a happy baby and we didn't want to lose that spark in her. But working with Kari was the best decision we ever made. She gave us a plan that was supportive, and doable and it actually worked. She answered all of our (MANY) questions & we never felt like we were alone. Now our daughter puts herself to sleep and sleeps through the night. She's still the same joyful, giggly Squish just finally rested. I can't recommend Kari enough. She didn't just help our baby sleep. She helped our whole family breathe again.

We have used several of Kari's services over the last few months from maternity and birth shoot to newborn photos and sleep consultation. We weren't sure if 6 weeks was too soon since Kari didn't recommend nighttime sleep training until 3 months but having a colicky, overtired baby who only wanted to sleep in our arms was a challenge. Kari helped set up a loose nap routine to build structure in our baby's day and now only a week in, he has become so good at napping in his crib during the day and no more colic! Kari has been extremely communicative and is passionate about sleep consulting, making the whole process so much smoother and supported so far!

Kari was one of the best decisions we made as new parents. She was punctual and reliable every single shift — which meant more than we expected when everything else felt unpredictable. Our daughter had to wear a Pavlik harness for hip dysplasia, and Kari adapted without missing a beat. No hesitation, no fuss — just capable, thoughtful care. She had a real gift for feedback. Whenever something was worth adjusting, she'd bring it up with kindness and give us concrete things to try. It never felt like criticism, just good guidance from someone who knew what she was doing. What stuck with us most: she checked in on our daughter on her nights off. That's not in any job description — it's just who she is. We'd recommend Kari to any family navigating those early months.

Co-sleeping transition
★★★★★

I reached out to Kari as we were in a facebook group together and I saw she was a pediatric sleep specialist. I had been co sleeping with my baby and was ready to transition her to her crib but I was uneasy about the transition. I needed the extra help, guidance and accountability to move forward. Kari was very responsive from the first time I reached out to her and has been since we connected. She wrote up a plan for the baby and I picked a date to start. The main thing that really help me were some of her professional tips and scenarios she gave, it all just clicked and really stayed with me when I was going through the transition. I won't spoil what she said, but I would suggest hiring her and you will find out all the secrets! I am happy to say we have made the transition and we are all sleeping very well! Thanks Kari for you guidance and the key points that helped make me do the transition, I am forever grateful!

Kari's sleep consultation was life changing! Before, my 9 month old daughter was waking up at least twice a night to nurse but sometimes every 1.5-2 hours and I was a zombie. Kari wrote out such a clear plan that we were able to implement it before our first meeting with her and baby girl slept through the night (11.5 hours) on night 1! Now, two weeks in and she is still sleeping through the night and yesterday she even napped in her crib! Kari provided an easy to follow path which she catered to our girl and our comfort level with crying and the whole family is happier because of it! Forever grateful!

With Kari's support, our 4.5 month old went from being rocked or fed to sleep and doing 100% contact naps to falling asleep independently in his crib for 1 hour+ naps. Before working with Kari, I couldn't imagine our baby falling asleep independently without endless hours of crying, and was very apprehensive to try. Kari provided the experience, confidence, and structure we needed to move ahead and help our baby develop those skills. We were amazed at the total transformation in his sleep that was so much faster and involved so much less tears than we imagined! Kari went above and beyond with her guidance and quick responses to our questions.

I am so grateful for Kari and her support with "sleep training" my son. She literally sat on the phone with me the first few nights and walked me through every step. Within one week he was falling to sleep on his own. I am so happy that I trusted Kari and her process because it worked like a charm and I just can't ever express how grateful I am for her. She helped me recalibrate feeding times, wake windows, naps and tummy time. She is literally Kari "Poppins" and I don't know where we'd be without her. I recommend her to every single parent I know without a moment of hesitation. Thank you Kari!

We were connected with Kari through Facebook and are so happy we found her! Our 5 month old went through a rough sleep regression and was only sleeping in 3-5hr stretches at night. After just one week of working with Kari, our baby has 2hr naps daily and has been sleeping 8-9hr stretches at night! She has taught us very useful tactics that we felt matched our style. She was easy to communicate with and allowed us to pick from options that would work for us

Our experience working with Kari was wonderful! Even starting ahead of our daughter's 3-months, we noticed a direct and substantially beneficial effect only a few days into Kari's sleep shaping/training. Kari was incredibly attentive and insightful, making for a great experience! We'd highly recommend Kari, and have already been telling our friends who are soon to be parents about her expertise.

Working with Kari has been nothing short of incredible. When we reached out for help, our seven-month-old was waking every hour at night, and we were beyond exhausted and completely sleep deprived. Kari stepped in with knowledge, confidence, and hands-on support. Over the course of just four days, she guided us through a personalized sleep coaching plan and was right there with us every step of the way. Her approach was supportive, clear, and incredibly effective. She completely transformed our baby's sleep habits—he now wakes only once during the night(if that), and his daytime naps have improved dramatically. I finally feel like myself again, and our whole home is calmer, happier, and better rested. What has meant even more is that Kari has continued to check in with us multiple times a day, offering reassurance, guidance, and encouragement even after the initial coaching. Her ongoing support has been amazing and truly above and beyond. Kari has changed my life for the better, and I am endlessly thankful for her. If you're struggling with your baby's sleep, don't wait—she is the absolute best.

Kari is absolutely wonderful! I worked with her to help my 5m old learn independent sleep. We were having trouble figuring out out an appropriate schedule & sleep training method. I reached out to Kari & she quickly helped me in the best way. We wanted to start sleep training immediately & Kari delivered. I reached out on Thursday & by Friday she had my daughter's sleep plan ready to go. She was very kind & responsive & easy to work with. With the method we chose, my daughter caught on really fast & was trained in just a few days (for night & naps!). I'm extremely grateful for Kari & highly recommend her services!

We are so glad we reached out to Kari when we did, rather than waiting until sleep became an even bigger challenge down the road. Our daughter, Hazel, was 5 weeks old, and we were desperate and completely sleep deprived. The only way she would sleep was on our chest, which, of course, isn't sustainable long-term. We knew sleep training isn't recommended this young but our friends recommended Kari's newborn package, which focuses on sleep "shaping" rather than traditional sleep training. Kari created a personalized plan with techniques and strategies to help Hazel develop independent sleep early on. Within the first week, Hazel was sleeping on her own, and I finally had time to rest and catch up on things. We highly recommend Kari to any parents that are struggling in the sleep department. She is a lifesaver!

We worked with Kari to help our 11-month-old transition away from falling asleep with a bottle and sleeping through the night without needing feeds. From the very first night, she slept all the way through! Kari was amazing — she gave us personalized guidance that really fit our family, and it made such a difference having someone to text when questions came up. She also helped my husband and I stay on the same page and feel confident in what we were doing. We're so grateful for her help and would 100% recommend her to any parent struggling with sleep!

I gifted sleep support services to my daughter and son-in-law as they prepare to welcome their second baby. They had been so exhausted, still up all night with my first grandbaby—20 months old, co-sleeping, and nursing through the night. Fast forward to just two weeks of working with Kari, and our little one is now sleeping in her own crib, through the night! This has been such a life-changing experience for our whole family. Kari is truly gifted at what she does, and I can't recommend her enough to anyone navigating sleep challenges with their little ones. 💕

Outstanding, life changing, knowledgeable, compassionate, patient, supportive, confident, the list goes on. This how our family would describe Kari through the sleep training adventure. Our little 7mo was navigating many issues. Nighttime feeds, dependence on sleep aids, small feeding amounts, dairy allergies, weight gain, sickness, new daycares. Despite having consulted books, friends, and our pediatrician, we were struggling to get new habits to stick. Kari thoroughly reviewed the issues we were navigating and came up with a plan. The end result: average 9-10hrs sleep per night, all feeds during the day, consistent naps, and a happy happy household. We're enjoying our lives so much now thanks to Kari. Throughout the training phase, Kari was incredibly responsive to our questions, firm and confident in her advice, supportive to both myself and my wife, and very helpful in determining what was within normal range and what seemed off, requiring plan adjustments. Kari has a structured approach that worked incredibly well for our little boy. We cannot recommend Kari enough, she's a master at her craft!

Kari has been incredible for our family. After seven months of severe sleep deprivation and struggling with our toddler's challenging sleep habits, we finally found the support we desperately needed. Kari stepped in with confidence, compassion, and a clear plan. Once we began following her protocol and guidance, everything changed for the better. Our 12-month-old adjusted to the new routine beautifully—sleeping through the night and weaning off the bottle far quicker than we ever imagined. I would have never found the confidence to make these changes without Kari encouraging us and leading us in the right direction. I wholeheartedly recommend Kari to any parent struggling with their little one's sleep routines. She has truly changed our family's life, and we are endlessly grateful.

Our 10-month-old twins were waking every 2–3 hours before we started working with Kari. She thoughtfully helped us adjust their feeding schedule first to ensure they were getting enough calories before beginning sleep training. With that foundation in place, they were sleeping through the night by the second night of training. Kari tracked their progress objectively and was essential in helping us stay consistent and avoid making emotional decisions. Everyone is more sleeping through the night and on a consistent nap schedule.

Kari helped our one year old finally sleep through the night. We had been struggling with multiple wake ups during the middle of the night that required over 45 minutes to get her back to sleep each time. We went from barely getting any sleep to peaceful nights. I loved Kari's easy to understand methods and instruction. She was very communicative and responsive to our questions any time we needed support. We highly recommend her and would work with her again if any need arose. Thank you Kari Poppinz :)

My husband and I were eager to have some nighttime help, and Kari went above and beyond. Kari is highly communicative, and even though we worked with her on a weekly basis, she made a point of checking in multiple times throughout the week. Kari is very kind, knowledgable, and willing to meet my husband and I's anxieties with a calm and steady confidence. Kari was willing to provide guidance on multiple topics, as well as holding space for my emotional needs and anxieties as a first time mother. Our baby's 3 months old, and Kari had great advice and tips on helping to foster independent sleep skills. As a mother herself, I feel like Kari "gets it" and is extremely eager to help us. Kari, we are so grateful for your guidance and great care- we look forward to continuing to work together in the future! I'd HIGHLY recommend if you're looking for someone to help make magic happen.
