Diana Zales

Hi! I'm Diana, owner of Zzzs by Zales pediatric sleep coaching and mother of two. I believe that healthy sleep and responsive parenting can go hand in hand. My goal is not just better sleep, it's helping families find a sustainable rhythm that supports both rest and connection. When parents feel supported and children feel secure, sleep becomes easier for everyone!

My approach is rooted in responsiveness, connection, and evidence-based sleep practices. I recognize that there is no one-size-fits-all solution to sleep, and I work closely with each family to create a plan that feels comfortable, realistic, and aligned with their parenting values. Whether you prefer a gradual approach, want to maintain a strong bedtime connection, or are looking for alternatives to traditional sleep training methods, I offer options tailored to meet your family's goals.
My philosophy

Meeting you where you are and helping you meet your sleep goals in a way that feels best for you!

Case Studies

Anonymized · with permission
Frequent Night Waking
5-month-old with frequent night wakings requiring parents to rock or feed to sleep each time. Parents prioritize secure attachment and wanted to make sure all needs were responded to. Over 2 weeks, we helped baby feel comfortable and confident in their sleep space. Baby was able to fall asleep and back to sleep independently resulting in 11-12 hours of night sleep for baby and a full night sleep for parents! Everyone was happier during the day and could enjoy time together.
Toddler Transition
3-year-old totally fighting bedtime, leading to parents lay on his floor until he fell asleep every night. Frequent night wakings going into parents' room and sleeping in their bed. Parents felt out of control and exhausted. Together we set clear bedtime expectations, implemented a sleep / communication plan, and empowered the toddler to sleep in his own room. By the end of the 2 weeks, he was looking forward to falling asleep in his own bed, where he stayed until his parents came to get him in the morning.

Night wakings, rocked/fed to sleep
★★★★★

Diana not only helped us teach our 7 month old son to sleep, she gave us back our life! Before Diana, our son was waking 6-7 times a night and needed to be rocked, fed or held to sleep. After 1 week, he was waking only 1-2x a night and was able to put himself back down independently. Diana was readily available all day and at most hours during the night. The real-time coaching was invaluable and does not compare to any course, instagram post or chat-bot. I would recommend Diana to anyone who is looking to improve the sleep habits of their child...you will not regret this decision!

Frequent night wakings
★★★★★

My experience with Diana was literally lifechanging. Before working with her, my son was waking up every 30-45 minutes, and I was at my wit's end. Within just a few days of implementing her advice, he started sleeping for 5-6 hours straight, dropped his night feeds, and reduced his wakings to just 2-3 times per night. By the end of our journey, he was sleeping through the night most nights. What really impressed me was how Diana helped him learn to fall asleep on his own and establish a consistent daily routine. It's been a total game-changer for our family - my son is finally rested and happy, and we're all feeling more energized and focused. The best part of my experience is that she never made me feel judged or frustrated, even when I needed to intervene earlier than planned. Instead, she encouraged me to trust my instincts as a mom and do what felt right for my son. This made me comfortable when we did have to go through some growing pains to improve his sleep - I could trust that I was doing what was best for my son, even when there were tears involved. Diana also set me up with tools and knowledge to continue troubleshooting future issues (sleep regressions, nap transitions, daycare, travel, etc). She has very graciously offered up her support whenever I need her, even past the 2 week engagement. She truly cares for her clients. Her services obviously have to have a start and end date, but I feel like she is fully invested in our success long term. I feel prepared to tackle challenges while knowing she's a text away if I need help. Thank you Diana!

Night wakings, co-sleeping
★★★★★

We couldn't be happier with our experience with Zzzs by Zales! My husband and I were at our wits end trying to sleep train our 9 month old baby. We co slept with him since he arrived, exclusively breastfed, and really let him take the lead on his sleep schedule, following his cues. We really thought we messed up when we finally tried to get on a schedule 8 months in, and after 30 days when he turned 9 months, we knew we needed help! Diana was recommended by a friend of a friend, and she has been a God Send. I booked an appointment late one night out of desperation for the next morning, and she was as cheerful as every ready to assist. Within 24 hours we had customized sleep plan with minimal crying, and unlimited support. Within 3 days, our son was self soothing himself and sleeping 5-6 hours without waking in his crib. WITHOUT THE CRY IT OUT METHOD. We couldn't believe it! We are at the end of 2 weeks and our son is sleeping 7-8 hours uninterrupted and my husband and I are consistently getting sleep and feeling well rested. Thank goodness for Diana and Zzzs for Zales. I'll recommend her to everyone and anyone who will listen!

Contact sleeping / only sleeping on chest
★★★★★

Before starting our process with Diana, our 2 month old would ONLY sleep on our chests. Day 1 of following our plan with Diana, he not only slept independently, but put himself to sleep which we never would have even considered he was capable of. Diana made the whole process seamless and stress free and by the end of our 2 weeks, our son was putting himself to sleep for both naps, and night time & we were sleeping better than we ever did. We are incredibly thankful for the insight and help Diana provided, as she was available to help us any time of the day / night with whatever was needed. We would absolutely recommend using Diana if you and your family are looking to get better sleep with your little ones!!!

4-month regression, night wakings
★★★★★

I spent 3 weeks trying to troubleshoot the 4 month regression before reaching out to a Diana. Working with her was the BEST decision we ever made!!! Before my son was waking every 2 hours overnight, but within 3 days on her custom plan/schedule for us he slept 12 hours overnight with little to no support from us. Even when we traveled over thanksgiving in a new sleeping environment, he was still able to do 12 uninterrupted hours 🙌🏻. I cannot recommend her enough!! Not only does she make a custom plan for your family’s wants/needs, she’s also available by text (seems like 24/7!) to help troubleshoot real time any issues you’re having. She truly is a miracle worker and we’re so grateful for all her support and guidance!

Night wakings
★★★★★

Working with Diana was nothing short of a dream. Going from waking up every 2 hours like clockwork to only waking up once per night in a matter of days with minimal crying exceeded my expectations. Diana lays the groundwork and foundation for you to be successful and is with you every step of the way. I loved the open engagement and ability to check in with her whenever I needed to gauge what to do next. I am so grateful for not only her support and expertise but also the kindhearted approach she took to making this work for our family. She is the ultimate coach! My only regret is not working with her sooner!! Thank you, Diana, for changing our baby’s relationship with sleep and setting our family up for future success and restful nights!

Independent sleeping (toddler)
★★★★★

Working with Diana was truly one of the best decisions we’ve made for our family. Our son was already 2 years old when we began experiencing sleep challenges, and we were struggling with helping him become an independent sleeper. Like many parents, my husband and I were hesitant to work with a sleep consultant. We thought we could manage on our own and weren’t sure how someone could really help. But Diana changed all of that. From our very first interaction, Diana made us feel so seen, heard, and supported. Her incredible patience and compassionate listening helped us feel comfortable and confident in the process. What stood out most was her flexibility and willingness to adapt her approach when things didn’t feel quite right. She never pushed a one-size-fits-all method and instead, she tailored everything to our family's needs and values. Diana was there for us every single day, often checking in multiple times, offering encouragement, and celebrating small wins. Her support through text, phone calls, and facetime made the journey feel less overwhelming. Even when I started to doubt if it would ever work, Diana reassured us with calm confidence and reminded us that we were making progress, even when it didn’t always feel like it (we needed these boosts of confidence a lot!!) Since working with Diana (we started in mid-April), our son is now a happy, well-rested independent sleeper (and so are we)! We feel proud of how we approached this transition, and that’s in large part thanks to Diana’s guidance and support. She truly became part of our team. I can’t recommend Diana and Zzzs by Zales highly enough. If you’re considering a sleep consultant, know that you’ll be in thoughtful, expert, and deeply caring hands with Diana. — Joannie D.

Short naps, multiple night wakings
★★★★★

Diana gave us our life back! Our 4 month old was a terrible sleeper from the jump, short naps, multiple night wakings - needless to say we were exhausted. Diana took the time to understand our baby and created a thoughtful sleep plan for us. I was so nervous to try sleep training, but she was so supportive and held our hand through every single step, answering any call or text. Our baby responded so well to the program and started sleeping 12 hours through the night by night 3, and naps connected shortly thereafter. I am finally able to get things done at home, have the energy to workout, and feel like myself again! I cannot recommend working with Diana enough. Your whole family will sleep again!

Multiple night wakings
★★★★★

We have truly had the most wonderful experience working with Diana. I was hesitant to hire a sleep consultant because I knew we had successfully sleep trained our first, however our second born was very different. He was waking up between 2-7 times at night, and at 7 months, I had enough. My husband and I couldn’t get on the same page and we needed help! Diana was so helpful, clearly communicated what needed to be done and understood how to help us so we could make the needed changes at night. She is patient, decisive and I appreciate that her services are reasonably priced. Within five days, our son slept 10.5 hours. The LONGEST stretch he had ever done and we all slept as well! He now puts himself to sleep with very little to no crying. I cannot thank her enough for helping our family!

Independent sleep, schedule
★★★★★

I could list 50+ reasons why I'm so thankful I worked with Diana but the number one reason is because of the confidence she gave my husband and me (and our baby girl). We were struggling with getting our daughter to fall asleep independently and through the night, and we knew the schedule we had her on needed to change but didn't know what to do. With Diana's help and guidance, our daughter was sleeping through until 6:30am (our goal wake-up time) within ONE DAY! Throughout the two weeks we worked with Diana, she learned how to put herself back to sleep unassisted and now if she wakes up early, she remains calm and hangs in her crib until we come get her. Diana listened to everything we had to say and tailored a plan and schedule to our needs. She answered every question with the level of detail I needed for my type-A brain to feel at ease and always made herself available for text messages and phone calls whenever we needed. We will be eternally grateful to Diana for providing us with the right tools and confidence to ensure everyone in the house is sleeping well through the night. I feel I've truly gained a friend through this experience and would recommend her to anyone who is experiencing any sleep-related challenges with their little one. I will absolutely be reaching out to her again if/when we feel we need a bit of assistance in the future. Hire with confidence!
