In an early diaper-free phase take your toddler to a playground far away from home. Sit on a bench, kick off your favorite ballerinas and think "How cute!" when she slips them on and stumbles off. When she stops to take them off and pour out the pee, don´t follow your reflex to hide and deny any relationship with your offspring. Just swallow your pride and disgust, put your shoes back on and squeak home.
