As a single mom, I live with my parents. It's been a great opportunity for my son - having my dad around as a positive male role model.

I'm one of those open communicators when it comes to body parts and my son, who is three, still takes showers with myself and my mom.

Tonight, my son followed my dad into the bathroom. He pointed to my dad's penis and said, "What's that?" My dad replied, "It's a penis." My son, in all of his infinite wisdom replied, "Big girls don't have penises." My dad encouraged him to go tell grammy, who he had the conversation with earlier, in the shower.

Next thing you know, my son is in the living room, lifting my mom's nightgown to do an inspection, shaking his head, saying nope, "Big girls don't have penises."

lol!
