Q: My baby is 16-weeks old and rolls over all the time. He even getting to where he wants to sleep on his belly. Should I let that happpen or is he still in danger of SIDS?
A: Once a baby is able to roll over, there is actually no way to keep him sleeping on his back. At that point, most babies are past the risk of SIDS. In addition, using things like body positioners or other ways to keep him sleeping on his back can be riskier than just letting him roll over.
