A.M.
I had the same situation with my 5 month old son and just had to go for it...starting with one arm out then moving to no swaddle at nap time and then ultimately swaddle free at nap time and night. You will probably have a few bad days but i felt my son would eventually have to learn to self soothe witout it and he had started rolling over in his sleep. He actually sleeps better now as he rolls over and sleeps on his tummy at some point and can suck his hands if needed.
