Developmental coaching performed by pediatric providers is a first-line, universal relational health promotion intervention. Separate, dedicated, developmental coaching through telehealth complements well-child visits by creating a more relaxed platform. These sessions address parent developmental concerns, allowing space for parent reflection and enhancing parent skills through dialogue and guided practice. The TREEHOUSE program, an outgrowth of the Grow Your Kids: TREE (Talk Read Engage Encourage) program developed by the Maryland Chapter Academy of Pediatrics in 2015, incorporates telehealth developmental coaching into pediatric primary care. Preliminary findings of this Health Resources & Services Administration-funded project indicate successful implementation with providers and positive feedback.
