Strange Interests

Recently E. has developed two very strange interests, combined with a new word, "doo." No, it has nothing to do with dogs or any other animals. She loves to touch my elbow or my feet and say "doo" very happily. Sometimes she'll even rub her nose back and forth against my elbow. And the feet fascination gets even weirder--she'll grab onto them in the shower and squeal or if she sees them on the floor, she'll get down to their level and squish her face on them. My sister would not understand, but it looks like I've finally found someone who appreciates my (large) feet.
