K.W.
If the back rubbing is working I would keep it up, I am sure you would rather sleep through the night but somthing has her changing, My son is 3 and I would say about half the time I still have to get up with him just to say "its ok" sometimes. Some nights he will wake up 6 or 7 times those ones wear me out. In the middle of the night I would say if you give her anything to drink do water, we did milk and it is a very, very VERY hard thing to break at least for us it was. Now i put him to bed with a sippy cup of water make sure I show him and say heres your water. Good luck
