Don't give in. She knows you'll give in. Just keep giving her the cup and tell her that her bottle is broken. My daughter went off the bottle at 21 months because she bit the nipple. I told her you broke the bottles - and she said OH - and was OK. My other got sick and couldn't suck out of the bottle so I just never gave it back to her and she was only like 18 months. Anyway - you can do it - just tell her no bottle and stick to it. She'll take it.
