A boy thing?

So in addition to Alex getting all these ailments that Grace never got, I am also finding other situations I never had to deal with before. In the past week I've had to call poison control (possibly eating Lipitor - no harm done), deal with a "string burn" on the back of his neck (that's what I get for giving Grace a ball of yarn to play with) and last night Alex managed to topple one of our stained glass windows on top of his head (small cut on his head and lots of little glass pieces in his hair, but luckily no emergency room trip needed). And on top of it all he has another runny nose and cough even though he just finished up a round of antibiotics. But through it all my funny little guy is still happy as ever. I don't know how much of it is a "boy thing" and how much is a "second child thing". But boy two kids in the same family sure can be different.
