T.H.
I would probably give it to her. My daughter has always had a bottle of water next to her bed, we did it to stop the "I'm thirsty" technique when trying to go to bed. I did worry when we started to potty train her that it would become an issue, but honestly, it didn't. Plus, the novelty of the water wore off within the first week or two and she doesn't drink nearly the amount she did at the beginning. I just use a sports bottle and refill it every few nights.
