DS is 14 weeks (tomorrow) and was sleeping a 5.5-6 hour stretch, waking to eat, and then going back down for 3-4 hours. He started really fighting the swaddle around 10 weeks, but was still sleeping well in it. Around 12 weeks he started to break out of the swaddle on a regular basis and struggle against it so much he would spit up all over his bed. So we started swaddle weaning last week. We tried with just one arm out/both arms out (but still swaddling his chest) and also tried the Merlin Magic Sleepsuit. His sleep has become HORRIBLE. He sleeps two hours when we first put him down and then we are lucky if he sleeps hour stretches for the rest of the night. It often takes 20-30 minutes to get him back to sleep just to get 30-40 minutes of sleep ourselves.
How long did it take your LO to get used to having their arms out of the swaddle? Does this seem like a normal reaction to swaddle weaning, or are we trying it too soon?
