Peppers really likes his babysitter Liz. I can tell because
1. His face lights up when she comes around.
2. His only has a category 7separation anxiety meltdown when I leave him with her.
3. He learned to pull himself up while she was here.
4. In the process of pulling himself up for the first time, he fell clean out of his crib. I think he did it just to impress her.
