My dd2 is 9 weeks and a bugger to get to sleep.. She usually gets overtired, up ages, kills my back, wakes up dd1 etc. etc. .... I know a lot of people try swaddling and this is one method i so far haven't tried (tried the feed u to sleep, bounce on one knee etc. methods!!)... How do you properly swaddle the baby?? Is it arms in or leave arms out??? Sleep on back or on side?? I'm confused, any advice pleasE????
