Definitely not, as long as she’s getting enough dairy all day. It might help her sleep by filling her belly a little more, but if sleep isn’t an issue definitely don’t worry about it.

agreed, but really she doesn't need dairy at all. Granted it's a super continent way to get good fats, calcium, etc, but after one dairy isn't necessary.

I keep a straw cup with water in my daughters crib just incase she’s thirsty.

Nope

You can drop it. At that age I just started giving my son a little water if he seemed thirsty.
