I see a lot of people say their newborn hates being swaddled or hates having their arms in but if you're not swaddling or youre swaddling with arms out and your baby is still not sleeping well then keep trying! It has been such an amazing tool for us. I dont know how we ever got by without swaddling him. Anytime he gets fussy or sleepy now we swaddle and he calms immediately.
