I see Ellen already answered, but I couldn't help but chuckle here. After raising two boys, (and Ellen has 3) you get so used to what they do, you have to just let them be boys or you will have a heart attack!
My oldest started dancing on the coffee table and jumping off at 15 mos. I went nuts trying to stop him - I had to keep the kitchen chairs upside down on the table at 19 mos after #2 was born, because I'd come back from changing a diaper and find him on top of the table.
So after a couple of years of panic, I had to relax and just trust they would be okay. I had a friend who raised boys ahead of me and she would just smile and shake her head and say that nothing a boy would do would ever surprise her - I would have to agree!
Boys are alot of fun, but it is a never ending adventure!
