When my LO came home from the hospital we swaddled with a blanket. We started using a sleep sack with a velcro swaddle part but recently whenever I put it on, my LO starts to fuss a little and grunt as if he's trying to break free of his pseudo straight jacket. This makes me think he doesnt like it. I'll then nurse him until he calms and gets drowsy. I've experimented and tried letting him sleep without the swaddle part but his little active arms will touch his face/head and then wake himself up! Should I still swaddle?
