The Trikester keeps rolling on his side when we put him in his crib unsawddled. We're afraid to swaddle because the (halo) blanket keeps winding up in his mouth. I've also read all this awful stuff about sleeping in the Rock and Play - positional asphyxiation when their chin rests on their chest (as his does) in the rock and play and they stop breathing. I'm an anxious mess and have not slept. Any suggestions?
