I've been following the Baby Whisperer book and have swaddled my 3 month old DS for the past month and it's been going well. However, in the last couple of weeks, he's been getting strong and manages to break free from the swaddle and can't sleep after that. He's waking up from naps and several times during the night and has to be reswaddled and resettled. More worryingly, sometimes when he breaks free, he somehow manages to pull the blanket over part of his face and I'm worried he might suffocate himself. I need to get him out of the swaddle. I have tried putting him down for naps with one arm out but he cries for 45mins then sleeps for 15 continually. Any ideas anyone?
