We've been struggling for a month and two weeks to get our baby to sleep without being swaddled. He can only sleep with his hands swaddled for 15-20 minutes at a time, and all of his limbs start flailing around! His face, ears, and hair are constantly being rubbed. Does anyone else have babies like this? When did your kids start sleeping with their hands swaddled?
