2 yr toddler. drinks alot and pees alot also. wake in the night screaming for water or juice. normally don't give it. is this habit or something else?

Deserves a visit: Many of these are just a drinking habit, but there is a rare condition where someone cannot re-claim the water that is purified in the kidney and these can become dehydrated overnight.Habit drinkers love the attention/process of drinking and asking for refills and their kidneys dilute their urine so much they need to keep drinking.Your doc can do some tests to exclude a real problem.
