Not All Sleep Coaches are Created Equal
With low-cost, weekend courses flooding the market, anyone can call themselves a baby & toddler “sleep expert.” But families deserve more than guesswork. At Tiny Transitions, our coaching is rooted in evidence-based, proven frameworks and over a decade of hands-on success. Because when it comes to your child’s sleep, winging it just isn’t good enough.
That feeling of walking on eggshells, the endless nights blurring into days, the desperate Google searches at 3 AM…
We remember it well.
For over a decade, we’ve been the quiet partners for thousands of families just like yours, gently guiding their little ones – from newborns to toddlers through school age and beyond– towards the peaceful sleep you all deserve.

Sleep isn’t a Luxury – It’s the Foundation
You’ve tried swaddles, sound machines, and a dozen “expert” tips on Instagram, but your child still isn’t sleeping. At Tiny Transitions, we bring 10+ years of trusted, results-driven pediatric sleep coaching to guide your family out of exhaustion and into a rhythm that works. For good.
Why Families Trust Tiny Transitions?
In a space flooded with guesswork, we’re grounded in results.
The sleep consulting industry is unregulated and many new coaches rely on templated scripts, not real experience. We’re different. Led by Courtney Zentz, nationally recognized Pediatric Sleep Expert and Founder of Tiny Transitions, our hand-selected team brings deep training, lived experience, and personalized coaching to families who are ready to reclaim their nights.
We’re not just “certified”- we’re clinically-informed, emotionally intelligent, and obsessed with helping families win at sleep.

What Families Say
“Courtney Zentz is incredible at what she does and is such a wealth of knowledge on all things sleep and children and beyond!! We hired Courtney to sleep train our 4 month old son (who HATED sleep) and to break his co-sleeping habits and she did just that! She came to our home the first night to support us through the process and show us the ropes and she followed up with calls and messages often to check in on him. We had lots come up with sickness, food allergies, teething, etc and she always helped us problem solve and get his sleeping back on track. She also gave us lots of tips and tricks for our 3 year old that have been amazing and well received by her! If you are looking for SLEEP, courtney will absolutely get your baby sleeping, even when you think it’s impossible! We are forever grateful for Courtney!”

“Erin Forish is truly the reason we got through this difficult time in our life. When we started working with Erin 6 weeks ago, she told us that our son would be able to be placed in his crib and us walk out without tears. We were so desperate for sleep, he would wake up every 90 minutes throughout the night. Now we place him in his crib and he is able to fall asleep and stay asleep on his own. Not only did we gain the knowledge to support him, but we got to see him gain confidence in putting himself to sleep without our support. Best money we have ever spent, thank you Erin!

“Let me just start by saying Tiny Transitions sleep consulting changed our life. Our little boy was such a good baby, except when it came to sleep. He was up every 2 hours, honestly, sometimes more. I finally decided something had to change and hired Kiley Pickett. I was so worried about how the transition to teaching him to sleep would go but Kiley was amazing!!! She provided so much support and helped me to be so confident during this journey. My little guy was sleeping through the night after just a couple days, and our bond has gotten so much stronger and I can’t thank her enough. If you are on the fence about hiring her, do it.”

Welcome to the Tiny Transitions Family
I’m Courtney Zentz, The Founder of Tiny Transitions
At Tiny Transitions, we understand your struggles because we’ve been there too. Our certified Pediatric & Adult Sleep Consultants specialize in gentle, effective methods that are customized to fit your family’s unique needs. With years of experience and a proven track record, we’re here to guide you every step of the way.
I am a formerly tired mom who wanted to go back to work when my first was just 4 weeks old. I was failing as a new parent and felt anxious and alone. I didn’t know what I was doing and didn’t have a village around me to help. A successful corporate career I could control, and I was good at it. Parenting, not so much. I had a baby who cried and nipples that bled. And I hated it. I was never so tired in my life. There had to be a better way.
I found sleep, and it was transformational. From there, I was hooked on supporting other women – this was my calling. It wasn’t long after that I became a Certified Sleep Consultant, Certified Lactation Counselor and Postpartum Doula.
Tiny Transitions was born. My life’s mission is to ensure no new parents ever felt as lost, alone, and unprepared for the biggest job of their life. Today, I reside in Philadelphia, PA with a team of baby, toddler and adult sleep coaches all across the U.S. ready to help in-home or virtually.

Ready for Sleep at Last?
Sleep is one of the most important gifts you can give your family. Let’s build a foundation that supports healthy sleep habits, not just for tonight, but for the long haul.
“Erin Forish, I just wanted to update you that sleep training has been a smash hit at home! While I haven’t done it, [REDACTED] are able to leave the room, and he can put himself to bed after some brief protesting. In fact, [REDACTED] and I have gotten up in the middle of the night, wondering when the shoe is going to drop, and lost sleep when V is peacefully sleeping on his own just fine without us.
But the real reason I am sharing this is because tonight, for whatever reason, [REDACTED] had a hard time putting himself to sleep. He’s usually out within 5–7 minutes after lights out, but tonight, it took him 30 minutes to get himself to bed, and you know what? Not a peep from his room! We watched him on the monitor wiggle his butt, twerk the mattress, and snake around the crib to find a good spot and he did it. all. on. his. own. No crying. No whining.
It was amazing to watch what he’s capable of and how far he’s come in less than a month! So sending kudos and many thanks to you for the encouragement and motivation to do this! At least for now, we are doing great!”
