Mariana Yancik

Mariana Yancik is a Certified Pediatric Sleep Consultant with a background in postpartum & infant care, known for offering calm, highly personalized support during the earliest and most demanding seasons of parenthood. Before specializing in sleep, she worked for years as a postpartum doula and certified newborn care specialist, guiding families through the newborn stage with discretion, confidence, and care.

Her work is shaped by both professional expertise and lived experience. Even with extensive training, becoming a mother herself transformed how she approaches sleep support. She understands the quiet overwhelm of night wakings, the weight of decision making, and the reality that motherhood was never meant to be done alone. This perspective allows her to support families with evidence based guidance while honoring each family’s values, instincts, and lifestyle.

Mariana offers one on one pediatric sleep support for newborns, babies and toddlers, with every plan thoughtfully tailored and responsive. Her approach is calm, intentional, and rooted in trust. She does not believe in rigid methods or one size fits all solutions. Instead, she helps families build sustainable sleep habits while making motherhood feel lighter and supported.

She has had the privilege of guiding families from around the world toward more rest, confidence, and balance at home. For Mariana, this work is deeply personal and grounded in the belief that well supported parents raise thriving children.

Born and raised in Brazil, Mariana moved to the United States over a decade ago in search of new opportunities and a fuller life. She is fluent in both English and Portuguese. Today, she lives in South Florida with her husband, their son Noah, and their dog Delray. She has a deep love for the beach and the slower, grounding moments it brings.
