This is the year you lost all your babyhood. No one would mistake you for a baby, and G-d forbid anyone dare call you a baby. "I'm a big boy," you will inevitably reply. Because you are.
This is also the year we made you use the potty. You are still not so sure that was a good idea.
You are smart as whip. You are funny. You are sweet. Your laugh could make the whole world laugh with you. You are dying to learn how to read. You love to play on the computer and all you want in life is an iPhone for your very own.
