Devon Clement, Pediatric Sleep Trainer

Devon has over 20 years experience loving on babies, and supporting new parents. As an experienced Postpartum Doula, Mommywise Certified Sleep Trainer, Devon helps parents get to know their babies, learn how to care for them, and to understand their needs.

She’ll cheer you on, help you build your confidence as a parent and, guaranteed—she’ll make you laugh! She knows that a good night’s sleep is the most valuable gift she can give parents, and she loves the look on their faces when they come out of their bedroom after their baby has slept 11-12 hours for the first time!

Erika Arenger, Pediatric Sleep Trainer

Erika knows what it feels like to be completely overwhelmed and exhausted as a new parent. Her twin daughters didn’t sleep for most of their first 2 years, and her whole family suffered through it. She researched endlessly to find a sleep training method that worked for her girls, but nothing she tried worked until she hired expert, live-in support. The stress of her early parenting years led her to become a Postpartum Doula and a Mommywise Sleep Trainer, so she can help parents get the rest and peace of mind they so desperately need. Her compassionate support before, during and after sleep training is invaluable to her clients who rave about her. Words they use to describe her include “lifesaver,” “sleep angel,” and “best parenting decision ever.”

Courtney Long, Pediatric Sleep Trainer

Courtney is an expert baby whisperer, and a sympathetic mom who’s experienced every new parent challenge. As a trained Postpartum Doula, Newborn Care Specialist, and Mommywise Certified Sleep Trainer with over ten years of experience, she brings a level of professionalism and care that is apparent in all of her work. Courtney is passionate about instilling confidence in parents so that they can make the parenting choices that feel right for them. When she isn’t helping families sleep, you can find her volunteering at her son’s school, or learning new skills (like ballet and soccer). She’s an exceptionally compassionate human, her laughter is contagious, and you will love having her in your home!

Meredith Coronato, Pediatric Sleep Trainer

Based in Brooklyn, Meredith has spent most of her adult life caring for new parents and babies as a postpartum, birth doula and Pilates instructor.

She is an expert at holding parents through the most challenging and emotional moments of early parenthood, and truly enjoys helping parents get to know their babies, feel confident with their parenting choices, and most importantly, getting the rest they need. She looks forward to helping you and your baby sleep, and be the fully rested and present parents you really want to be.

Shas 20 years of experience as a Certified Postpartum Doula, Newborn Care Specialist, Mommywise Sleep Trainer, and is the mother of three. After Mommywise helped her sleep train her own daughter, KayLee’s drive to help more families feel well rested led her to joining the Mommywise team.

Tiffany Decker, Pediatric Sleep Trainer

Tiffany has been helping families sleep and thrive for over 7 years. She understands the toll that sleep deprivation has on babies and parents because she’s been there. Her firstborn didn’t sleep through the night for 18 months, at times waking every 45 minutes. When she sought help, she only found judgement and sleep advice that didn’t work for her baby. As the founder of Birthing Stone and Seattle Sleep Training, she loves sharing her gift of helping babies sleep, while supporting parents to feel comfortable and confident with the process. Her favorite part of her work is hearing parents share the positive impact that restful sleep brings for the whole family. She looks forward to helping you and your family sleep and thrive!
