How can I get my baby to sleep without swaddling him? Is it bad to keep swaddling him?

Depends. Infant swaddling is a transitional measure that replicates the snug feeling of the womb & calms baby when they can't handle the random movement of arms & legs. That said, they didn't need to breath in the womb and without room for arms & legs to move they don't develop muscle tone.To tight is a problem for both. The goal is to gradually loosen the wrap & have it gone at a month.
