Sleep suit


Does anyone have any recommendations for sleep suits or sacks? My son is 9 weeks old and at times, thrashes all night long and is unable to fall asleep. It’s as if he is trying to crawl out of his skin. I have tried swaddling and he hates it — cries until he gets out. I have tried the magic blanket, halo swaddle, the hands up swaddle with no luck! I’m wondering if sleep sacks might help. I read about baby Merlin’s magic sleep suit on here and I’ve seen several other sleep sacks on instagram. He sleeps in the rock in play. Any advice or suggestions is much appreciated!
