Lily spells her name

So, I was typing on my laptop, Amara was napping, and Lily was playing with blocks. Then Lily says to me, "Mom, I spelled Lily." I looked down and she had Y i and 2 backwards Ls she made out of blocks laying on the floor. Technically, that spells YiLL, but I'm not picky. I've never seen her make letters before, so I was a little shocked. All the letters from her name are there on the floor and she created it! Of course I am a very proud mother and think my daughter is so smart and amazing, so I decided to use my webcam to video her accomplishment.
