So here's a little tip from me to you:
If your kid doesn't eat for 2 days and has to be rehydrated in the ER and then feels amazingly better so wants to eat everything he can get his hands on? Yah, DON'T let him get his hands on mini-cheeseburgers.
Today, Lil'Bro made it about 1.5 hrs into the school day before yarfing all over his classroom carpet. I owe his teacher dinner. AFTER he's better.
