Slumberly Sleep Coaching

Slumberly is led by Lydia Harden, who brings an unusually strong academic foundation to the sleep consulting field. She holds a master's degree in Developmental and Educational Psychology from Boston College and has accumulated over a decade of hands-on experience working directly with families. She carries dual certifications as both a Pediatric Sleep Consultant and a Newborn Care Specialist — credentials that allow her to support families from the earliest days of a newborn's life through the toddler years.

Services Offered

• In-home sleep training — Hands-on support where Lydia comes to your home in the Boston area, observes routines, and guides implementation in person
• Virtual consultations — Remote coaching sessions for families anywhere in the US who prefer a flexible format
• Baby sleep programs — Structured plans for children ages 4–24 months, customized based on developmental stage and family dynamics
• Newborn care specialist support — Guidance during the newborn phase (0–4 months), including feeding, soothing, and early routine-building

Approach

Lydia approaches sleep through the lens of developmental psychology research — not just behavioral modification. She considers how attachment patterns, cognitive development, motor milestones, and temperament intersect with a child's ability to sleep independently. This means her plans are designed to be developmentally appropriate at every stage, rather than applying the same techniques regardless of the child's maturity.

Who This Practice Is Best For

Parents who want a consultant whose recommendations are grounded in developmental science, not just anecdotal experience or a single certification program. Lydia's Boston College training and decade-plus of hands-on work create a foundation that bridges academic research and practical application.

Location

Based in Boston, MA, with virtual sessions available nationwide.

Frequently Asked Questions

What is Lydia's educational background? Lydia holds a master's degree in Developmental and Educational Psychology from Boston College and has over 10 years of hands-on experience with families. She is dually certified as a Pediatric Sleep Consultant and Newborn Care Specialist.

What ages does Slumberly work with? Sleep training programs are available for babies 4–24 months. Newborn care support is available from birth for families who want early guidance before formal sleep training age.

How does the developmental psychology background affect the sleep plan? Lydia considers attachment, cognitive milestones, motor development, and temperament when building plans. This means recommendations are matched to where your child actually is developmentally — not where a generic chart says they should be.

Are in-home visits available outside Boston? In-home visits are available in the Boston metro area. Families outside the region can access the same level of personalized support through virtual sessions.

Is newborn care support different from sleep consulting? Yes. Newborn care support covers the 0–4 month window before formal sleep training is developmentally appropriate. It focuses on feeding, soothing, safe sleep practices, and building early routines that set the stage for later sleep training success.
