Yep - you guessed it. Urinary Track Infection. Yay. :)
Two funny things have happened since we got out of there.
We went to the drug store to get his antibiotics filled. Michael said he wanted to hand her the prescription. The girl working the counter took it from him and asked 'Is this your medicine?'. Michael said 'Yes. My penis hurts inside so this will make it better.'. We had to laugh. I mean, she ASKED so she shouldn't be surprised when a four year old starts telling her about his penis!
Right before dinner, Michael went off to the potty and I heard him yelling something to me. When I went in there, he said something about a cup. I thought maybe he was talking about the cup he had to pee in at the doctor. Nope! Turns out he had gotten one of their Dixie cups off the counter and peed in it! Then he dumped it in the potty and flushed, and threw away the cup! He says he wants to pee in cups all of the time now, so I had to explain that we only do that when doctors ask us to. I don't know if it sunk in.
