K.T.
I would think as long as she is wetting her diapers, and when she crys you see tears then she is fine. Just watch for signs of dehydration. I was once told that children do get fluid from foods not just from drinking. Keep a cup of something out for her so if she does decide to drink she will. At her age she might want to be in control and if you push the issue of her drinking she might just fight back. Best of Luck to you.
