Hi Rachel

I don't think I have any advice on this, except to say that they get better at not losing the dummy and/or sleeping without it. My DD still goes to sleep with a dummy but rarely wakes up with it and has been doing so for quite some time. If she isn't waking during the night I would suggest she can resettle without it and is probably just having shorter sleeps during the day or being woken for other reasons as well (light, noise, etc).
