As I cleaned up a scrape on Lena's hand this afternoon I explained to her that the medicine and Dora band-aid would make it all better.  Maddie watched very closely while rubbing her knee.  She tried to tell me her boo boo hurt too, but she hasn't had a mark on her knee in weeks.  I told her she only got a band-aid if she had a boo boo.  She said, "Want boo boo, please!"
