Liza Bourke

Listening, empathy, and deep understanding are at the heart of my approach. I have a holistic approach to sleep, because I know that sleep is only part of a child’s whole day and is influenced by things like culture, family dynamics, cognitive and physical development, nutrition, social/emotional well-being, and communication. My goal is to guide parents to be confident sleep leaders in their home and to gain the tools they need to finally make the changes to sleep that they want to see.
My philosophy

I believe that sleep training can maintain a balance between both being responsive to our children while also encouraging their independence. I also believe that effective sleep support isn't about rigid methods and prescriptive tactics--You deserve sleep coaching that is grounded in responsiveness and observation, and works to uncover the root causes of sleep disruptions while deepening connections with your child.

Case Studies

Anonymized · with permission
4-Month Regression
2.5 year old who was rocked to sleep his entire life and co-slept most of the night since birth. Parents were exhausted and wanted a gradual approach that would teach him to be comfortable and confident in his own crib the entire night. By the end of 2 weeks, the child was consistently sleeping through the night and loved going into his crib at bedtime!
Toddler Transition
7 month old baby who was rocked to sleep at bedtime and woke every 30-60 minutes the entire night. Baby was also held for all naps. Parents wanted longer stretches of sleep at night, fewer night feedings, a predictable schedule, and independent naps. By the end of 2 weeks, baby was falling asleep on his own happily at bedtime, down to one night feeding, had eased into the 3 to 2 nap transition, and was taking 2 long, independent crib naps.

I cannot say enough good things about Liza, I just wish I would have reached out 6 months ago. I had my reservations about sleep training but was instantly comforted by Liza’s expertise and compassion. She listened to our concerns and really created a plan with our goals in mind. She provided with options and daily check-ins and support. Our new bedtime routine is something I look forward to each night, and our little guy has slept through the night without any issues. It has honestly been the greatest investment in our son and ourselves. 10/10 recommend!! Sourced from Google Reviews.

Our experience with Coach Liza gave us our lives back!! She helped our family to develop a sleep plan that worked for us and our toddler. She was thorough during intake to make sure she understood where we were starting. Overall, we gained 2+hours of sleep per night. Even better.....we gained a kiddo who has the confidence and skills to sleep! Sourced from Google Reviews.

Working with Liza was the best thing we could have done. We have a 3 year old little boy who has always been a great sleeper. All the sudden he decided he didn’t want to sleep in his toddler bed, would get up multiple times a night and we tried to figure it out for over a month on our own before finding Liza. Starting with Liza was so amazing because she was responsive and so helpful. My husband and I would be texting her at 9 pm at night saying what our little guy was doing and she would message us back immediately with suggestions and encouragement for us. She really made it a priority to be there for us and also to get to know our little guy. She sent him videos, praised him when he did good and made sleep seem fun for him. She would text us every morning asking how our night went and then immediately came up with new solutions to the problems we were having. She never stopped trying to help us figure out why he didn’t want to stay in his bed. By night 6 he was sleeping in his bed all night again by himself. Our little guy was very stubborn and resistant to things as well but Liza never got worked up she just kept coming up with more solutions to try until we finally figured it out. I feel like I made a friend through this experience and am so very thankful for everything she did for our family. We are all sleeping again and it feels amazing. Thank you Liza for everything you did. We truly appreciate you. Sourced from Google Reviews.

I can’t rave enough about our experience with Liza and Summit Slumber Pediatric Sleep Consulting! Neither us or our 2 year old son had gotten a full night’s sleep more than a handful of times since he was born. I thought he was just a bad sleeper and we’d have to (barely) function like this for several more years but decided to try working with Liza at the recommendation of a coworker. It’s truly the best thing we could’ve done! The transition period was difficult, as things can be with a toddler, but Liza was there with us every step of the way and her support was invaluable. It’s been weeks now of him sleeping through the night and even taking longer, more peaceful naps than ever before. It’s had the biggest positive impact on our lives and we are so grateful!

Words cannot begin to describe how thankful my family is for meeting and working with Liza. Before meeting I was up every 2 hours with my son, nursing throughout the night, only contact napping and following a three nap schedule. Liza helped create a plan and an approach on how to get my son sleeping independently and to cut down to one nursing session overnight. Not only did she help walk us through the transition of independent sleep, but she also helped us transition to two naps at the same time. She really had her work cut out for her with my son and by the end of our two weeks he was falling asleep by himself for naps (in the crib) and at night with only one nursing session overnight. Liza was always available when we needed her help with adjusting our daytime schedule due to short naps, car naps or anything we ran into. When she told us how to adjust she explained her reasoning and helped me understand how to do it on my own for when she was no longer coaching us. I cannot recommend Liza enough, she will change your life. We now have a much happier 7 month old, I have time to myself and time to spend with my husband. Sourced from Google Reviews.

I'm so grateful for Liza's help from Summit Slumber! We had been struggling with our 2.5 year old staying in bed and the bedtime process was taking hours. Liza gave us some strategies and games we could play with him that completely helped. Bedtime is no longer a daily struggle and I'm so thankful! Sourced from Google Reviews.

Words can’t even describe how much Liza from Summit Slumber has helped our family. Our 10 month old little girl needed to be rocked to sleep for naps and at bedtime, she woke up every 40-45 minutes throughout the night and would not go in her cot. Me and my partner would take shifts so one of us could sleep whilst the other stayed up holding our daughter. When we first started the two week package we never in a million years thought it would work so going into our first call with Liza we were very apprehensive. Liza was so welcoming during our call and made sure she explained everything and went into detail about our desired strategy. We then went onto start it that very same night, and with Liza’s support she was asleep on her own independently within 50 minutes which we couldn’t believe and slept from 8pm till 12.30am which doesn’t sound a lot but to us it was massive! Liza was so responsive with her replies and was the support we needed! Fast forward to ending the two week programme our life has changed massively, our daughter will now go down in her cot for both her naps independently and will go down at bedtime independently, giving me and my partner our evenings back to spend together. We have even had two nights of her sleeping through. I really describe how much Liza has changed our life’s and our little girls life and we will be forever grateful for this opportunity.
