You know you're a parent of toddlers when...

The poopy diaper falling off the changing table and landing face down on a pile of books is merely annoying, instead of Haz-Mat suit gross.

You stop wondering why your house has a persistent urine aroma.

Your own clothing becomes an acceptable place to wipe runny noses, ketchupy faces and sandy hands.

On the first day of Spring, you find yourself driving in the warm sun with the windows down and Elmo blaring.

You pull the car over to take off your child's shirt because he is hysterical that he spilled chocolate milk on it. You don't argue when he asks to remain shirtless.

Singing the "A,B,C's", "wheels on the bus" or "B-I-N-G-O" while at a restaurant for dinner isn't embarrassing. Nor is congratulating your child on his pooping in the potty.

You wake up after 4 hours of sleep, even if no children are awake, because your body is convinced this is enough.

Having enough time to complete the simple task of loading the dishwasher, going to the bathroom, brushing your teeth or folding a load of laundry is both rare and exhilarating.

You love every minute of it.
