Small One was standing on a chair in the kitchen yesterday, watching me as I rifled through the junk drawer. She picked up a package of safety latches, and looked at it. It has a picture of a toddler on it, so she said "Oh, this is for babies!"
I nodded, distractedly, still looking for something, and she asked "What is it?"
I said "It's just something to keep babies from hurting themselves."
She looked at the package for a minute more.
Then she hit herself in the head with it, and frowned.
Clearly, that thing doesn't work AT ALL.
