Since Nolan didn't like the Pediasure, the dietitian suggested adding 1/3 cup powdered milk to a cup of chocolate milk. They call this "mighty milk" and it has double the calories of a regular glass of milk. We went out and bought some carnation powdered milk and added it to a cup of chocolate milk - Nolan liked the taste, so that was a big win.
Yesterday, he ate breakfast (one and a half waffles) and then I gave him his morning "mighty milk" snack at about 10:30am. He would drink a little and then be done for a while, then drink a little more. I spent most of the day chasing him with a sippy cup, trying to get him to drink the entire volume. It took until 4:00pm, and he didn't eat his lunch or much of dinner because of it. We still had one more cup to get into him, so we sat over him and didn't let him move until he had downed the entire cup of milk.
He drank this one over the course of an hour, and didn't feel well. His stomach bloated and he was "too full."
He then had severe diarrhea and, while still bloated, seemed to feel a bit better.
For comparison purposes, his stomach is typically flat and not tight-as-a-drum and bloated:
I have emailed the surgeon and I am waiting for some direction - I can't make the kid sick like this, but obviously he needs more calories.
I really wish they'd look into the "why" of the bloating, because maybe we could treat that and have a boy who is able to eat normally without all of this craziness!
