Okay so my hospital (which really sucked) taught us how to swaddle. They told us to wrap her arm in the blank it, put it over her chest and tuck the side under her. Then do the same with the other arm so that her arms were lying across her chest. Well my baby is a little over 9 weeks and she hates to be swaddled. Then I read the happiest baby on the block and they said to swaddle with the arms down at their sides. Would this actually make a difference? I haven't tried this yet since she is sleeping. Just curious if arm position really matters!
