i have been swaddling my baby, quite successfully, since he was about 3 weeks old. he's now a big bruiser of 15 weeks and more than capable of getting both arms and a leg out of the blanket much of the time. i am still persisting with swaddling him for naps and bedtime though as it works really well in letting him know it's time for a sleep and he settles pretty well once i've done it. i'm just wondering when i should stop and what replaces it as his cue to sleep. his arm movements are still pretty jerky so i don't want to stop right now, but sometimes it seems to be his night's work to wriggle free of the blanket and i feel it may be becoming slightly counter-productive. any advice would be much appreciated....
