Sennet has been brushing his own teeth, and flossing, for some time now. I usually pick him up to reach the sink so he can rinse out the toothpaste and spit into the sink (one of his favorite parts of the process). The other night when I asked if he was ready to rinse & spit, he leaned over the sink and did it himself. It took me a second to realize that he had lifted himself off his step stool and was dangling there.
