Hi, I'm Courtney Zentz, CLC


Bringing sleep-filled nights to your home is what I’m all about. 

Sleep deprivation can wreak havoc on everyday life.

Sleep impacts cognitive and mental health in children with a direct association between short sleep duration and depression, anxiety, impulsive behavior, and poor cognitive performance.

It can lead to tantrums of epic proportions, irritability, brain fog, a suppressed immune system, and impaired judgment. 

The long-term effects are even more frightening.

Sleeping 5 hours a night has the same effect on the brain as being intoxicated.

90% of brain growth occurs before the age of 5.

At the age of 3, a child’s brain has reached 90% of its full potential.

Only 1 in 10 teenagers get the right amount of sleep at night. 

But, you don’t have to worry about that, because I’m here to make sure your sleep issues get solved before long-term damage can be done.

Sleep is non-negotiable.

It is not a luxury or an indulgence, but a necessity for our bodies to reset.

We work intimately with families from around the world to build a customized sleep training program, that is tailored to your parenting style and their personality, so every member of your home can rest easy and without the need to “cry-it-out.”. 

Our approach to sleep coaching allows parents to feel confident in the gentle changes we make to transform their children into the best sleepers in town. 

We provide the industry best support, knowledge, guidance, and know-how you need to bring all-night-long-zzzz’s to your home, in just a few short days.

(Yes… really!)  

If you could sleep through the night, make bedtime a breeze, create predictability in your day and give you some time back, what is holding you back?

Why Choose Tiny Transitions Sleep Consulting?

You wouldn’t trust your child with just anyone. Working with a professional who brings experience, industry-leading thought leadership, compassion, and service are what I stand for.

A sleep-deprived family in a vulnerable position needs someone they can count on and trust, and that’s what we do here at Tiny Transitions. I am not only a Certified Pediatric Sleep Professional, but I am also a Postpartum Doula, Infant Mental Health Provider, and a Certified Lactation Counselor, and I am regularly asked to contribute my knowledge and expertise in the space of pediatric sleep. 

I didn’t just ‘graduate’ from some online sleep certification program and start seeing clients… (yep, that happens…much more then you realize.) I trained under contributors at the forefront of pediatric sleep, who are some of the best in the world. It is important when you are looking for someone to provide you with support or sleep consulting that you understand their experience. 

I get children. I get sleep. I get the tiny transitions in life that can make you feel like you’re losing your mind. I understand how hard the transition into motherhood can be – even if it’s not your first time. My expertise stretches far beyond just sleep, so your family gets the most holistic care possible from myself and my team of Certified Sleep Specialists.

I’m a mom, just like you. I’ve walked the road you are walking, which means I get it. No judgment here. Parenting life is hard. Sleep troubles can make it substantially harder. I’m here to simplify the sleep process and get you some rest! 

You are not alone.

71% of infants wake at least once in the night.

50% of preschool and school-aged children wake in the night.

90% of teenagers don’t get the right amount of sleep.

Ready for a happy, rested child?
