i went to sleep school with owen when he was 5 mths and they said to stop wrapping him(he was wriggling out of it mmost of the time anyway), so we just went cold turkey from there..it was horrid for about 2 days but then he was fine, better than before actually..but if you can i'd wait til the weekend or sometime when your partners around to help and also start at night when jay sleeps best..this is the advice i was given. it's so great once you can stop wrapping..they will sleep absolutely anywhere!!esp since your little jay doesn't take a dummy either!!(owen does)
good luck!!
