Re: Eating normal, poops normal, not drinking??
You could maybe try a different bottled water to see if he'll drink more of a different brand. They can taste different (trust me), so that might help. If he won't drink more of any kind, maybe try putting a tiny bit of Gatorade in the water or something? Or 100% apple juice that you'd get for babies. Maybe a bit of sweetness or flavor will encourage him to drink more.
