21: Why Ages 3-4 Can Feel like a Preview of Adolescence: Understanding the Brain of Your “Threenager” with Sarah Piel, Ms.Ed, PMH-C
There's plenty of advice and support for the magical, challenging year of two—but what about year three? We sat down with Early Years Expert Sarah Piel, M.S.Ed., PMH-C, to explore what's really happening in the "threenager brain." Together, we unpack the emotional and developmental shifts behind this stage, and why it can feel like a preview of adolescence with huge surges of independence and plenty of volatility. Grab a coffee and lean in with this chat, where Sarah beautifully takes us through everything from whining, frustration tolerance, ways to play, to the precursor skills that actually work for desirable traits like sharing and empathetic apologies that are not just performative. Find Sarah at sarahpiel.com and learn about all the ways you can work with her! As the founder of Piel Developmental Consulting, she can work with: Babies, toddlers, and young children — one-to-one and in playgroups. Parents and caregivers — one-to-one, in parenting groups, and with their child in playgroups. Schools and organizations — consulting, evaluating, and leading workshops.
