When you are two you have a mind of your own and are old enough to let everyone know what is on it. You want the bathroom door open when mommy wants it closed, and you want the bathroom door closed when mommy wants it open. Thankfully, reverse pyschology works pretty well on a two-year-old.
When you are two "cookies" is a perfectly acceptable answer no matter what the question is. Breakfast, lunch, snack, dinner...cookies are the fifth food group.
When you are two you wake up one morning (about 6 weeks ago) and realize you don't own a helmet and that is a problem. Once you own your helmet you decide that you must wear it sometimes no matter what else is going on...oh and don't forget the knee and elbow pads. All before you've even had a chance to change out of your pajamas.
