Hi, I had to chuckle when I saw your post. I also had the same problem with my son. He was drinking his formula out of a bottle until he was 5 and 1/2. He finally stopped when he went to kindergarten. The clinic assured me this would probably happen. In the meantime I just tried not to make an issue of it. Better having them drink out of a bottle then not drink their formula at all. Have you ever tried getting her one of those cups with the built in straw? This might help if you haven’t tried it already. My daughter with PKU did this. She had no problem getting off the bottle as long as she had the cup and straw. Good luck and don’t worry. I promise you she won’t be going to highschool with that bottle. haha.
