Can't help sorry.

My DD is 2 1/2 and she still has a bottle of milk in the morning first thing and also at night, although she will have a full 250ml bottle. On top of that she has a bottle of water that she has in bed if she needs a drink in the night.

My thought is that it is a comfort thing and she only drink from drink bottles during the day and the time will come when she will decide she won't want a bottle anymore or when her brothers no longer have bottles. I'm not too stressed about it if it means she gets some extra milk into her
