Debbie, we used to wrap, but had to stop when Claire about 3 months old. From about 2 months on, she just refused to be wrapped at all, and from about 6 weeks she would also push her feet out the bottom of the wrap. So, of course, she would get cold and wake up cranky because she would also kick off her blankets, and when I went to get her, she would feel like an icicle. I bought her a sleeping bag when she was 3 months so she wouldnt get so cold at night. The sleeping bag hasnt made any difference in terms of how well or how quickly she settles, or how long she sleeps, but at least she doesnt get so cold at night now. I also was worried about her wiggling and pushing herself out of the blanket, and that is why I got her a sleeping bag!
