Does anyone have this cups? How do you like it? Like it or not? My daughter will be 13 months next week However she still needs a bottle for her milk and idk why ?🤷🏻‍♀️ she drinks water and her home made juice on sippy cups perfectly fine she has different ones with straws and soft spout but she won’t drink her milk on any. I know she can still have her bottle which I don’t mind for now but I’m trying to make sure she’ll be ok when we transition, her pediatrician said to to start the wean process by 15 months but I honestly don’t think we’ll be ready by then.
