Boy went on a 2 day vacation with grandparents and extended family without me.
He should only be on raw.
Since I wasn't there, he didn't eat the raw meat he had packed and just ate fruit and apple juice... too sweet stuff.
he came back with some parts flared up.
So I'm thinking carb / fruit carb / fructose overdose.
Today he is on very low carb diet. Mostly rawish carnivorous diet. And maybe for the next few days until he balances out.
