Newborn Baby Sleeping through the Night

As award-winning sleep consultants,
we take the guesswork out of sleep training.

We get it. We have been there and know first hand how hard parenting is, especially doing it on little sleep. You have come to the right place. If you are a parent searching for solutions to help your child sleep, you have come to the right place.
  • Do you feel like your baby won’t sleep?
  • Are you struggling to get your baby to sleep through the night?
  • Does every nap feel like a battle?
  • Is rocking or nursing to sleep no longer working?
  • Does your school-aged child have anxiety before bed or struggle staying in their bed?
  • Would you like to make naps easier (& longer)?
  • Do you miss your partner, the feeling of a good night of sleep (& your sanity)?
As certified pediatric sleep experts, we have helped families all over the world get the sleep everyone needs to feel their best. Tiny Transitions was founded because we understand that a well-rested child is happier, eats better and has more energy to grow and explore their surroundings. As a Certified Sleep Sense™ Consultant and Certified Lactation Counselor, I understand there are important dynamics to every family. The approach my team and I use is quite different from other “sleep coaching” services out there, it is not a “cry it out” solution and is completely customized to your child’s needs and your parenting style.
The sleep consulting services and approach to improving your child’s sleep are very straightforward: We provide each family with an understanding of sleep, how things you may be doing could be blocking your success, why sleep is so important, and how it can be impacting your family in ways you did not even realize. We will lay out a customized sleep plan in a way that lets you make choices about the right approach to sleep training for your child, as all children are different and no one knows your child better than you.
We provide coaching to families through private client engagement or through our group programs, both designed to help you achieve success, educate you on what to expect on your new sleep journey and ensure that when you are sleep training, it’s a gentle and effective approach. We work with children from birth through school age and have become the sleep specialist that families all over the world can trust.

Courtney Zentz, CLC
Founder, Tiny Transitions

Hello, my name is Courtney Zentz and I am a pediatric sleep professional, postpartum doula and certified lactation counselor. I deal with all things sleep, since let’s face it, we all need more of it. Research shows that our youth are especially deprived of sleep and we as parents did not even realize it or know how it was possible to get them more. That's where I come in. As a professional sleep consultant, I am dedicated to helping parents learn the skills to teach their children to become independent, healthy sleepers (and get themselves more sleep in the process.)

I work intimately with families from around the globe to build a customized program that allows you as parents to feel confident in the gentle changes we will make to transform you children into the best sleepers on your block. I provide the support, knowledge, guidance and know how to get it done in just a few short days. (Yes... really!)

I am the mother of a lovely little boy, Max and a sweet young girl, Sovella and have always felt passionate about making sleep a priority in my family’s life. I strongly believe that healthy sleep habits mean happy, healthy and active children. I can’t imagine a more rewarding career. I love meeting and working with parents and their children and witnessing the transformation that takes place in their health and happiness as we work together.

Rosie Hawley
Pediatric Sleep Specialist

Hi there! I’m Rosie, a Pediatric Sleep Specialist based in Montclair, NJ and I LOVE sleep. I am the mother to a spirited little boy named Mikey and have a baby girl on the way. If you’re reading this, you’re probably where I was about a year and a half ago – desperate for some sleep!

I started my journey with sleep education when my son was about 3.5 months old. We had reached the dreaded 4-month sleep regression and I was in what I liked to call “nap jail” – locked in my son’s room 3-4 times a day, desperately trying anything to get him to sleep. When bedtime came around, I distinctly remember doing squats around the house, with my son in tow, hoping he would fall asleep! I was exhausted and felt as though I couldn’t be a great mom if I was sleep deprived around the clock. To make matters worse, it was evident that my baby boy was also in need of sleep! Sound familiar?

Through the process of teaching my son to fall asleep independently, I remember feeling a strong need for constant reassurance. This ultimately led me to the decision to become a sleep consultant. I wanted the opportunity to be able to give parents that reassurance every step of the way.

At the end of the day, we all just want the best for our children! Rest assured, through our partnership, we will be there every step of the way to help you get your child to sleep.

Clare’s transformation is unbelievable. We took our eyes off her for one second yesterday and she was sitting in the empty bathtub because she realized it was “night time.” She leads us through the routine & it’s so painless. She’s also so much happier during the day. And she’s still sleeping! It’s amazing!
