Emma - Nicholas is exactly the same. I was planning to get rid of the dummy over the weekend as he had a cold and couldn't really breathe through his nose with the dummy in. Also, it was causing problems through the day sleeps as as soon as it fell out, he would cry for it.I have found that he has a really big mouth (in the nicest possible way of course) and I have changed his dummies to these huge 12month size ones so he can actually keep it in his mouth. My DD had a dummy until she was 2 1/2 and then threw them out herself. She only ever had them for sleep and it was never an issue.

i have decided not to worry about the dummy now, and leave him with it. He usually spits it out when he is sound asleep anyway, and I am hoping that this waking every 1/2 hour is just a phase! It can't last forever (god I hope not anyway). I give Nic his last feed at 6.30pm and he usually goes through to 7am. Even now that he is waking all night, I don't feed him unless nothing else works. Good luck.
