Here's a list from an almost 4-year-old perspective:

And this is how you wrap a bike:
Oakley is all boy and figured out how to make "hot-dog-shooters." Sweet, I wonder how many hot dog pellets I'll be sweeping up from here on out.
Some of my favorite things about 4-year-old Oakley are:
-He busts into beat-box any given moment. Old-school, like your mom's trying to rap.
-His takes on phrases, ie: "...I've ever seen" is "never I seen" and "whole entire world" is "whole in China word."
-He loves to hug girls, a little too long.
He is so great and so far, 4 is my favorite year!
