Dear S.,
my name is M. and I have three children ages 10, 2 1/2, and an 8 month old. Now as nice as swaddling is it can be breeched as you are finding out, and as they get older it gets harder to really please them in any way when it comes to sleep, that's why you need to let him find his comfort zone. It took my 10 year old to convince me that holding the baby to much was going to bite me in my bottom, if you know what I mean. I guess she knew b/c of her little brother and boy is he attached to me. Back to the advise, I eventually had to let my baby Bella the youngest scream herself to sleep instead of laying with her, holding her and walking or rocking my three favorites. I guess she was about 5 months old and it was heart wrenching, because the first two children I just spoiled rotten in that department of sleeping. That is why my son Henry still crawls into my bed every night without fail. So eventually I just got adjusted to lying Isabella in her crib and hearing the screaming. Low and behold she stopped all the crying and eventually just dozed off after about 3 weeks of gut renching screams so tough love does work. So away with the swaddle and endure the pain let him find his groove. I suggest starting in the morning and keep going until he finds his nitch, oh give him that fav blankie and what ever comforts him. I hope this helps, M.
