Dental Floss: A Girl's Best Friend

Yes, Ladies and Gentlemen, Lexi LOVES her dental floss. Or rather, Mom's dental floss, which Lexi has been very attached to the last several days. We can't figure out why. She wants to carry it everywhere. It went house hunting with us on Tuesday night and to the playground this morning. She doesn't do much with it besides hold it but I did take the actual floss out of it. What will she be into next?
