We're learning so much as the twins grow older. Since we have boy/girl twins, we sometimes struggle with explaining gender differences to them. It usually goes something like this: girls wear barrettes, girls wear dresses, etc. Ironically, there isn't much that a boy does that a girl can't do. But, barrettes and dresses, daddy draws the line there.
The other day, Morgan was going through our list of family & friends: Morgan is girl, Tanner is a boy, Mommy is a girl, Daddy is a boy, Grandma is a girl, etc...
Randy looked over at her and said "Morgan, what's the difference between a girl and a boy?"
Morgan looked at him, grinned slyly, lowered her voice and ducked her head:
"Daddy, boys have penises."
