Fun Before Safety?

As we hauled out the Christmas lights to decorate our tree this weekend, Matilda was inspired to play doctor using the little lights. She would wave them at my ears like her pediatrician does with the otoscope and then move on to peer into my eyes, nose, and mouth. It was a fun bit of creative play that we didn't think to discourage. Now, however, I am paranoid as I constantly find her sidling up to the Christmas tree and shoving the colorful light bulbs dangerously close to her eardrum or eyeball.
