Tips on weaning off night bottle

I leave a water bottle with my LG, and she takes sips from it during the night, does not even wake us up for it anymore, she is now 2 and 1/2

Maybe she is just thirsty? I need a drink of water often during the night...

I'm looking for some tips to wean my LG off of her night bottle? She still wakes to drink at night. I've tried changing to water opposed to milk, but it makes no difference. She still drinks even if it's just water. TIA!
