Understandably, parents can be nervous about having the birds-and-the-bees talk with their children.
But Sarah Jessica Parker was so anxious about the whole thing that she ended up giving her son James Wilke a bowdlerized version of how humans reproduce when he was just 2.
As she explained to David Letterman on "The Late Show" Monday, it all came out of a misunderstanding. James was just asking where a security cloth he called his "baby" came from, and she misinterpreted what he wanted to know. So since "the talk" is a little hard to have with a child who's barely talking himself, she came up with a little story.
"I told him that he had one seed," she said. "And there was a young woman named Mary who he would meet in [his] sophomore year of college, and that she was going to be very smart and lovely, came from a nice family, and that he would choose Mary to give his seed to. But he had only one!"
Good news for the next generation: James Wilke has been better informed as he's grown older.
