13 month old only wants bottle

Looking for advice.

My 13 month old will not drink out of anything except a bottle. I’ve tried putting water, milk and even juice in her sippy cup and she will NOT take it. Usually just takes one sip and pushes it away…this is where I usually give in and give her a bottle.

Well, I wanted to stop cold turkey cause I’m worried the bottle will effect her teeth. This is day 2 with just her sippy cup (and yes I’ve tried other cups too, still a hard no) and she barely drinks. Her diapers haven’t been too wet because she will take a few sips throughout the day. Whether it’s water or milk. What do I do? Do I just give her the bottle back…I’m scared of dehydration. It’s so rough lately 😭
