Hi E.,
This really seems to be going around. = / We're going through the exact same thing right now. It's been awful. I'm sorry your family has been hit, too.
My son hasn't had much of an appetite until tonight - this is day 3 for us. He actually ate well, but I noticed the sores were on his tongue for the first time today. We're doing Tylenol to try to avoid stomach upset.
I went to Target and bought those HappyTot organic superfoods. They're in the babyfood aisle, packaged in little single-serving squeezie containers (about $1.20/ea). They can feed themselves right from the container. Each one has a fruit, vegetable, and salba (supergrain) puree blend with protein, fiber, antioxidents and omega-3s. E loves them even when he's not sick, but they're coming in especially handy now that he can't tolerate much else. I feel ok with it bc what he's getting is still balanced and healthy. I keep them in the fridge and he picks out the one he wants. I also gave him some cool grapes and he seemed to like them.
I hope your family is out of the woods soon. No fun.
