Don’t know if I’m behind the curve but I found a YouTube video yesterday that showed a technique called a double swaddle. My little man gets out of a traditional swaddle and even the swaddle sacks with velcro almost as soon as I put him down. He loves to move in his sleep and wakes himself up in an hour or less once his arms are out. Tried this double swaddle last night and he slept for 4 hours before he was able to wiggle one arm out! In the video the lady puts her swaddled baby into a sleep sack which I’m sure would help but I’m afraid he’ll get too hot that way. So for now the double swaddle is what we’ll stick with and I suggest everyone check out the video and try it!
