Because babies sleep safest on their backs, they need dedicated awake time on their tummies to build the muscles that back-sleeping doesn't. Tummy time strengthens the neck, shoulders, and core — the foundation for rolling, sitting, crawling — and helps prevent flat spots on the head.
Start from the first days home: the AAP suggests short sessions of 3–5 minutes, two to three times a day, building gradually toward a total of 15–30 minutes daily by around 7 weeks and up to an hour spread through the day by 3 months. Always:
Plenty of babies protest at first — the position is hard work. Try:
Brief head-lifting in the early weeks; steadier 45–90° head control by 2–3 months; pushing up on forearms around 3–4 months; and eventually pivoting and rolling. If baby strongly resists all tummy time, always turns their head one way, or you notice a persistent flat spot, mention it at your next checkup.
*Always consult your pediatrician for advice specific to your baby.*
