Hi sharon,
Lily didn't drop her bedtime bottle until she was 14mths old, they say this is usually the last bottle that most babies drop . I wouldn't worry about it too much if it is not broken why fix it!!
If you are worried about she is having too much milk then perhaps cut out the one that she has with her supper!
HTH

ps: i noticed on your ticker that she is nearly 1 yr old!!! when is ellas bday??
