question: my 2 year old has been drinking 5 to 6 bottles of the 16.9 ounce bottles of water a day and 1 at least in the night when he wakes up, and of course having to pee way often now, it seems to have started a few weeks ago when he was sick and we took him off of milk due to the congestion, he is all better now but I am concerned about all of the water he is drinking
