Hi, since she doesn't sleep with the bottle is slightly easier i think. You can wean her off bottle slowly by removing the nipple off the bottle and replace it with a straw first to slowly let her get used to it, then remove the straw eventually. Tell her that milk comes in a straw/cup form now.
or...go cold turkey... just remove all bottles and tell her now she is a big girl she would start to use a "big girl" cup for her milk. bring her shopping to choose her own cup. make it like a fun activity for her.
