When Colby started to roll from his belly to his back a little over a week ago, we decided it was time to start breaking him of the habit of sleeping in a swaddle. We did about a week with just one arm out and this morning I left both arms out. He has done amazing all day falling asleep quickly with both arms out of his swaddle. His two naps this morning, he didn't sleep as long as normal, but I think that had more to do with the fact that he is stuffy and not eating well instead of having both arms free. This afternoon, he ate like normal and has been sleeping great!
