These early movements strengthen coordination, build neural pathways, and support future skills like balance, writing, and language. Understanding—and supporting—these milestones helps your child develop confidence and thrive as they grow.

Discover key infant milestones from 0 to 3 months, including first smiles, cooing, improved head control, tummy time progress, early rolling, and social engagement. Learn what’s typical, how to support your baby’s development, and when to reach out to a pediatrician or physical therapist for guidance.
