I chatted with Seth and Isabella's mom tonight, for probably half an hour before she left and another half hour after. We hadn't seen each other in two months. The beforehand was all about the wedding; the afterward was all about the kids.
Apparently Isabella, who's two on Easter Sunday, went through a phase recently of, not to quote Freud, penis envy. It started as, "Mommy, Seth has penis, I want penis," and escalated into, "Mommy, I really really want penis!!" After about two and a half weeks, she came to a grand realization.
"Mommy, Seth big boy, he have penis. Isabella big girl, have bagina!"
This is why I love working with toddlers.
