You should start tummy time soon after giving birth. Tummy time can begin with just 1-2 minutes a few times per day, gradually increasing to 10-15 minutes as your baby grows stronger. Tummy time is important for your baby’s growth. It helps strengthen their muscles and teaches them how to lift their head, crawl and prevents flat spots from forming on their head. If your baby doesn’t like tummy time, try having them lie on your chest while you play with their arms and legs.
