Way to go, teaching the baby about pan lids!
My best friend from high school, her parents called her son when he was two, "pequeño diablo" because he liked to crawl into the cabinets and do the pan banging thing (they had raised 4 children, including twins and forgotten everything they knew about it -- I had to come over when my girlfriend was visiting her parents (she lives in Arizona, they lived in Maryland) and was taking a shower and watch Kevin, her son, because her parents couldn't be relied on to pay close enough attention!). I had a little teeshirt made up for himi with that name on it and gave it to them as a present :-)
