I used to swaddle by son during night ..But in the mid of night when he gets up he unswaddles it and puts the cloth on his face and cries for help. This may lead to suffocation when I am asleep and left the baby unattended, so I decided not to swaddle him at nights and stopped this for the past 1 week. Baby used to sleep 4 hours stretch at night but for the past 10 days he is waking up every 2 hours at night . Is this because I left him unswaddled and he is looking for it or could it be for any other reason?
