I wrapped my DD until she was 13 months old. I figured she would let me know when she didnt want it anymore. One night she tried busting out of it and this went on for a couple of nights. I was worried I wouldnt get her to sleep if I didn't wrap her. Anyway, I stopped wrapping her and she has been sleeping well ever since.

I didnt use any special wrap either....I just wrapped her in a light blanket...maybe try that?
