Awww!! Poor Ethan!!! I hope ALex doesn't catch it.
D's right, milk is a no no. see if he'll drink plain cold water. Oni loves water.
As far as the BRAT diet, I would stay AWAY from it. My nephew JUST got a severe intestional blockage from it. He had the SAME thing Ethan has. and his butt got burned SOOOO bad!
His Dr put him on immodium to slow the diarrhea along with the BRAT diet(which BLOWS! lol!)
If he's not peeing, DEFINATELY call his Dr. They'll prob put him on the BRAT diet, but make sure you UP the applesauce part of the diet. And use REAL bananas, not baby food.
And the pedialite popsickles are a GREAT idea! I'm sure he'll LOVE them!!
