Four headaches since surgery....

I am a little bummed. I took the kids to the park tonight and Sam did his usual hang over the swing thing. After a few minutes he came to me and said that he was tired. I asked if his head hurt and he said yes. Then he staggered off to the play structure. After sitting on the slide for 5 minutes or so he felt better. I am just disappointed that it was such an obvious cause. The others were the first day after we came home from the hospital (5/23), the really hot day we had the follow up at Gillette (6/9) and Wednesday (6/15) when we got to bed so late.
