hun, i wouldnt worry too much bottles at this age arent as important as what they would of been prob 6 months before hand, i assume she is eating solids now so that also effects her wanting to drink milk which fills them up so if she is full she wont want that much of it 2 bottles of milk seems fine to me i was gonna say 2-3 bottles cause thats how my son was too...
relax n dont worry every kid is different n thats what makes them unique..
