I took cues from DD. She started to break free at night. I would wean by starting w/one arm out, then both. Then move to a sleep sack so they still have that feeling of being eclosed, but not restrained. HTH.
I was wondering about this too. The only difference is that my daughter has started to sneek her hands out the top when she wakes up to eat. Does this me she is ready to not be swaddled?
We weaned gradually - one arm out, then both, then Halo Sleepsack. He adjusted pretty well to doing it gradually, and now sleeps in the sleepsack great.
