DD is 3months and to be fair a very good sleeper. We have been trying the putting down drowsy but awake and she is sleeping from around 8pm-4am. Problem is during this time she is wriggling an arm free out of her miracle blanket. Once the arm is out it's like she thinks its morning and starts to coo away to herself. I don't want to encourage 4am as a time to get up so this is my quandary; do I swaddle her and feed her back to sleep (if she will!) or if are you supposed to leave them to babble in the dark and hope that they get the message no one is playing and eventually fall asleep on her own again?
