Lj certainly knows all of her body parts (as her Dr. asked me this week!). She really knows them. The funny thing to us is that when we ask her where "mommy" or "daddy" is she signs them. The lower chin sign is for "mama" and the forehead sign is for "daddy". I wanted to get video of this as any day now, she will point to US instead of signing the word for us. We can't help but take pride in her every move. She sure is an adorable little one!
