We've recently had to start swaddling my 5 month old because she cannot stop moving her arms and waking herself up. Like taking an hour to fall asleep, waking up every 30 minutes because she's pulling out her paci, pulling her hair, trying to eat her clothes, trying to touch the wall, you get the picture. We started swaddling her very tightly in one of the Summer infant swaddle me velcro swaddlers. It worked for a few days but she's started busting out of it and waking up again. I think she might be too big for it but I know that people usually stop swaddling at this age, not start. Should I see if I can size up? Should I go the traditional swaddle route? Do I need to double swaddle? What was your experience with a flailing baby and what solutions worked for you?
