Little man is under the weather

My poor little guy is not feeling well. He went swimming all day yesterday. Afterwards, he told me his tummy hurt, and then told me he had to throw up. He threw up several times during the night, and early this morning. Every time he tried to drink or eat he wouldn't be able to hold it down. Daddy stayed home with him today, and got him to eat a couple crackers. He ate a couple bites of pasta salad this evening and drank some ice tea, which he's held down so far. Poor little guy. I hate when he's sick, and there is nothing I can do about it. I can't stop thinking about him at work... I wish I could be sick for him.
