Our Mackenzie Rose at 12 months (she's just turned 2) was on 2 bottles a day - I weaned her to cows milk pretty much from 12 months. She was a great eater of solids so she was easy to drop bottles from. Like Min, I don't really remember dropping the bottles she really did it herself. When she wasn't really interested in a bottle or didn't drink much I think from memory the next day I just tried her without it and we went from there. Every baby is different and some need the extra bottles to get thru the day. Just play it by ear and see how you go.
