It is fine to swaddle your baby.
There is no evidence to recommend swaddling as a strategy to reduce the risk of SIDS. Swaddling, or wrapping the infant in a light blanket is often used to calm the infant. However, make sure that the baby is always on his or her back when swaddled. The swaddle should not be too tight or make it hard for the baby to breathe or move his or her hips, to avoid hip dysplasia. When your baby looks like he or she is trying to roll over, you should stop swaddling.
