The last couple nights we have tried putting our 2.5 month old to sleep without putting him in a swaddler, he falls asleep in my arms but as soon as I put him down he starts waving his arms and legs and wakes himself up.. We have been using a sleep sack thinking that it would be a smoother transition.. He wakes up every hour kicking his legs and waving his arms and doesn't go back to sleep.. Finally at 2:30 this morning I put him back in a swaddler and he fell asleep and slept till 6:00am.. Anyone have any tips on how to get my little guy to sleep without being in a swaddler? It's so frustrating since he breaks his arms out of his swaddler now anyways!!
