Make Tummy Time Fun
Babies spend a lot of time on their backs, now that it's clear that having them sleep this way can reduce sudden infant death syndrome (SIDS). But those who always lie sunny-side up can develop flat spots on their skulls and have delayed motor-skill development. The solution: tummy time.
Once your baby is about 2 months old, put her on her belly for up to ten minutes a few times a day, under your watch. She may not like it at first -- she'll be working the muscles she uses to roll over, sit up, and eventually stand and walk, and that's strenuous. To make it enjoyable for you both:
Play baby airplane
Lie on your back with your knees perpendicular to the floor and put your baby on your shins, facing you. Holding her hands, very gently rock or do ab crunches.
Hit the mat
Infant activity mats can make tummy time a treat. If you don't have one, try dangling a toy in front of your baby and placing a rolled towel or nursing pillow under her chest to keep her comfortable.
Lie face-to-face with your baby and make silly noises or sing her name to keep her attention.
