We ditched the wrap the first time around at about 3 months I think. We just went cold turkey and DS didn't really notice the difference. We started again, believe it or not, when he was around 6 months and did it for another month. He began to roll over in the cot and the rolling coincided with taking a long time to get to sleep. The swaddling helped for about a month and then he worked out how to worm his way out of it. We swaddled in a cot sheet at 6 months as he was too big for his wraps.
