Dummy Vs Thumb

I have been causing Mummy some sleepless nights this week because my Dummy keeps falling out while I am asleep so I cry (or shout) for her to put it back in for me. I have been waking her up 4 times a night and now she is fed up so she is trying to get me to give it up. We are having a bit of a battle about it but she is sure she is going to win. Well if that's her attitude I had better get used to my thumb!!
