I have no idea mate cos we are doing the same thing here.
DH even tried to break off the handle of the dummy the other day - but couldnt - just ended up breaking it so now it catches her fingers and she cries cos it hurts
You can buy dummies without the handle....
I would be letting her roll over, my DS needed his dummy and would wake constantly for it until he started to roll over and sleep on his tummy. I was very concerned intially, but after talking with the maternal health nurse was assured that it was okay if they did it themselves. Once i gave up on keeping him on his back and let him go over, I would often check on him to see he was sleeping without his dummy.. He was older though around 15 months and had gone into his own bed, sick of co-sleeping with us
Good luck.
DD went thru a couple of weeks of waking herself by rolling over. I did think about chocking her in with something, but in the end perservered (sp?) and of her own accord, she learnt to roll over and stay asleep. Now, she rolls over as soon as you place her in the cot and is fast asleep. I don't know whether this helps with the dummy problem, but maybe as blackduckies said, it may help her to sleep without her dummy. I think DD was just over 6 months when she started sleeping on her tummy, and I panicked but did alot of reading and looked on the SIDS site, and as long as they can roll over themselves and lift their own chest/head up, then they should be ok to sleep on their tummy.
