This post is a bit late, but just a point of reference for myself.

WZ is now 2 years old, I bought him a Wall-E cake because it's one of the things he can recognize on sight. More importantly because they don't make Mario cakes. :P So.. 2 years and WZ has went from this

To this.

I guess not much changed for appearances wise. On the behavioral side, he stopped asking for his pacifier a few days before his birthday. Heck, when I stuffed it in his mouth during one of his tantrums he hurled it across the room.

Now if only I can get him toilet trained.
