ds2 is 3.5mo
am finding swaddling a pita - inevitably i have to reswaddle him at some point in the night as he's managed to free his arms and is getting crotchety
and have to unswaddle and reswaddle before/after night feeds
but it's always worked in terms of getting him to sleep fairly quickly
and when he's swaddled in the daytime he sleeps longer than otherwise would be the case (1.5hrs rather than catnapping)
have just settled him in a sleeping bag but have doubts about how long he'll stay asleep (have tried a couple of times before but given up fairly quickly)
