I stopped wrapping DS1 when he could roll onto his belly. I didn't want him wrapped and not have his hands free to be able to push his face up off the mattress.

DS2 is very similar to your daughter. I stopped wrapping him at 3 weeks as he would spend more time fighting it than sleeping. He's only a few weeks older than your daughter actually. He sleeps in a very thick sleeping bag with arms so it's not easy for him to get his hands to his face anyway.

I assume wrapping is not the only sleep cue? Dark room, cot, feed prior and dummy are our cues. When we stopped wrapping the sleeping bag just became a new cue, as well as the other stuff that we didn't change.
