Now I Know My ABCs

Simon has two letter puzzles that are among his favorite toys. One is a wooden puzzle with small letters, and the other is a big foam puzzle with larger letters. For the last few weeks, Simon has been bringing me letters. Each time he hands me a letter, I tell him what it is. Until a few nights ago, I didn't know how much information he was retaining. I randomly asked him to bring me the "S" and he did. I continued to quiz him and he brought me about 15 letters when I asked for them. I was shocked! He's only 17 months old!
Now he also says the name of the letters randomly. He knows most of them by name, and a few of them by sound ( U is "oooo" and Z is "zzzzz") I wish I had it on video, but he won't do it on command. Whenever I hold a letter and say "What is this Simon?" he laughs hysterically. I'm not too sure why, but apparently it's funny.

I also have to include this picture. Last week, Simon and I went to Roberts Craft to get some paper. Simon was mad, so the clerk brought us a balloon. It was a hit. Simon talked to it all the way home and played with it first thing the next morning. The next day, I realized I didn't have everything I needed, and we had to go back to Roberts. Again, when we walked in, the clerk gave Simon a balloon. She tied it to his ankle, but he somehow untied it and it floated away. She brought us yet another balloon. Needless to say; we're big fans of Roberts now. Simon loved his balloon so much, he wouldn't part with it for breakfast, so it joined him in his high chair.
