We fed both boys some turkey sausage with "modified milk ingredients" this weekend. I'd bought the sausage (from M&M) last month, but we didn't get around to eating it until this weekend.
I don't think Andrew ate any of it on Saturday. But he did eat some on Sunday, and complained, "I feel sick" about an hour later. He retched a little into the sink, but didn't actually throw up. Then he ate half a bite of sausage this morning, and refused the rest. That was when Tony read the box, and there were the "modified milk ingredients", about five ingredients into the list.
I have no idea what I was reading when I bought that box of sausages. Normally, I read the ingredients on any new product two or three times, just to make sure that I haven't missed any of the secret words for dairy (whey, casein, lact-anything).
And I was eating it too, which explains why Geoff picked up a tummy-rash and had some mucousy poop on Saturday and Sunday. Sigh. I'm pretty sure he's got the same dairy allergy as Andrew does. Oh well, as others have told me, at least we know how to deal with it, this time around.
