B.C.
My 11 month old does the same exact thing, and so does the 8 month old that I babysit. Except, they like the dvd collection the most. I actually started swatting my daughter's hand, and she laughs at that too. She just started crawling into the fireplace. Today she pulled the flue down and soot poured all over her. I can't keep her away! Good luck, it just gets worse. Just stay consistent, but he won't stop this any time soon. There's too much to explore!
