We spent yesterday afternoon organizing the toys in Riley's room. She rediscovered some old favorites and developed some new favorites, too. Like a toy doctor's syringe that I have no clue how/when/where we acquired.
So Riley spent the rest of the afternoon administering faux shots. But only after warning me first, "I need to give you a shot, Mommy. This going to be reeeeally hurt."
(If it did, in fact, hurt, I was laughing too hard to notice.)
