Swaddling never lasted for me...my kids were just to big and strong I guess. Addison was very cold natured..so she got layered with blankets on her...then she slept great. If she was cold...she did not sleep. She had a onesie, socks, footed pj's, mittens, then light blanket and heavy blanket on her. She slept like a rock...I know it goes against all the SID's stuff but that was the only way she slept.
