Apparently we're doing something wrong

This is the window in the kids room. That hole in the window was the result of Ryan banging his head into it because he didn't want to take a nap. (Just a bump on his head, no cuts or anything - thank goodness!)

Apparently, we're doing something wrong with our almost 3 year old son. I'm at a loss right now...

(Unfortunately, even though we weren't planning anything big, now we have to replace a window instead of have a birthday party. Not that he'll understand...)
