DS will only sleep in his shawl. Without it he wakes himself up with his arms. He was managing to unravel hi shawl and it was going over his head. We tried a sleep bag but again he kept waking. Now he gets wrapped in shawl then sleeping bag on top. This has been working very well until to nights ago he started rolling onto his side. Iam worried he goes onto his front and might not manage to roll back over with so much wrapping and may suffocate. Suggestions please???
