A: Many moms have been telling me that their babies don’t like to be on their tummies. It’s becoming more common today because of the recommendation that babies sleep on their backs. The “Back to Sleep” campaign has been very successful in decreasing the number of infant deaths from SIDS, which is really good news. However, as a result, babies aren’t spending as much time on their tummies as they used to and they’re rolling over a little later than in the past. But don’t worry about that. Your baby will eventually gain the upper body strength necessary to push up and to roll over, so there’s no need to rush those milestones.

When you plan tummy-time play with your son, be sure enough time has passed after a meal so he’ll be comfortable. At first, keep him on his tummy for a few minutes at a time, allowing him to get used to that position.

Toys with mirrors might encourage your son to play longer while on his tummy, especially if the mirror is angled so baby can look at himself. If your son can hold his head up while on his tummy, he’ll be delighted looking at his own face in the mirror. You might even try playing peek-a-boo with him using the mirror, flipping the mirror down and then up again so he can see his face appear and disappear. Other toys are designed to encourage babies to use their arms and hands to push up their upper body and feature colorful, engaging activities to motivate baby's efforts.
