Cohen used to be the same when he was sick he would only have milk. Not even any food. He is 3 next mth and only just stopped having a bottle about the beginning of December last yr. The only reason he stopped was we lost the only bottle that he had (I eventually found it under the coffee table) I told him that we didn't know where it was and I asked him if he knew where it was to which he said No. He said "awwww my bottle" but I didn't hear anything else about it after that. So we progressed to a sippy cup. when we moved interstate a few wks later we stayed at my DH's parent's house for a few nights and when we moved into our new house we accidentally left the sippy cup at Poppy's place. I explaned that we had left it there and that we couldn't go back for a little while to get it so I just gave him some milk in a cup. for the last wk he hasn't even touched his milk and I have stopped giving it to him all together. I think when the time is right for your little girl she will stop with the bottle and it won't be a big issue one day she will just drop it. Why go to all the hassle of having her crying and upset. it's just a bottle of milk after all.
