Founder, Not a Peep Sleep Coach

Hello! I am happy you are here. I founded Not A Peep with ONE thing in mind: making parenthood enjoyable for everyone. Because when one member of the family is sleep deprived, no one is happy. I once was a tired mom too! I thank my oldest older, Alina, for the very existence of Not A Peep. 

Through Not A Peep, I have had the fortune of helping over 900 families around the world. I was born and raised in Colombia, and I currently live in Philadelphia with my husband and three girls. When I am not helping families, you can find me giving workshops, dancing in my kitchen, riding my bicycle along the Delaware river, and watching Miraculous on repeat with my girls. 

I wish more people were as kind, professional and supportive as Maria. Even though we are not in the same city, Maria was able to help us with our baby’s sleep; she always picked up the phone or texted us back. I don’t think you can get this kind of service with any other Sleep Consultant (and there’s thousands out there). Our baby now sleeps the night through!!! Thank you Maria, my only regret is not hiring you before.

What people say ABOUT Maria

Maria saved our lives! She turned what was a really difficult and hopeless period of sleep deprivation into one where we felt so guided and supported, with dramatic results within a day. We now sleep soundly through the night and enjoy great naps, and most importantly, can enjoy our baby so, so much because of it. Working with her has been the single best investment we’ve made in our baby’s life thus far. You won’t regret it. Thank you Maria!

If you’re unsure about booking Maria, don’t hesitate to call her—you won’t regret it. We have twin girls and tried everything we read about sleep training, but nothing worked. I even found myself in tears when they woke from short naps despite all our efforts. They would only nap when held and with a pacifier. Out of desperation, I reached out to Maria—and it turned out to be one of the best decisions we’ve made for our family. Maria created a detailed plan and provided consistent follow-up, guidance, and encouragement. By trusting her approach, we now have our evenings back to cook, clean, and spend time together. Best of all, we’re getting full 12-hour nights of sleep. Our babies now sleep independently—no pacifier, no rocking or holding—and even eat better during the day. Thanks to Maria, our twin girls are thriving: active, happy, and well-rested.

Maria is truly a god send. We hired her to help with sleep training when my daughter was five months old. I was very nervous about sleep training as I never expected or planned to do that. Maria’s sleep training method is very gentle and we got to be with our daughter the whole time while she was falling asleep. Ever since working with Maria our daughters sleep is the envy of all other parents. Truly has been the best money I’ve spent in my parenting journey so far.
