Swaddling your baby is AMAZING! I have yet to meet a baby that was against swaddling! I highly recommend it to any parent that's having a hard time calming their little one, or having trouble getting them to sleep. I swaddled Tyler until he was 3.5 months.
Love this swaddle...
This is what I use now that my little guy's out of the swaddle, Sleepsack.
This comes in Fleece or cotton!
There's also a great video our friend Shannon sent us called "Happiest Baby on the block." My husband learned a lot from this and felt more confident with his swaddling and calming techniques.
