How many ounces of fluid should my 12 month old be having?

I give my daughter 3 bottles of milk a day: when she wakes up, during the day usually before a nap, and one right before bed. I give her a sippy of juice or water and she’ll drink it throughout the day. So she could have anywhere from 1-3 sippy cups a day with her bottles. It really varies. It’s never a set amount. She sometimes says “baba” when she wants one but I don’t feel like she’s getting enough fluids. These past two nights while in the bath she tries drinking the bath water. Do you think I’m not giving her enough fluids. I’m getting worried because I don’t want her to get dehydrated. She has a lot of wet diapers tho.

Anyways, how many bottles of what fluid do you give your baby a day. Is there a specific time in-between each bottle?
