There are some things I’ve had a hard time explaining to my kids. Not the obvious things, like how babies are made. That was easy. / When my daughter, Tashi, asked me at nine, I said, “I went to a sperm bank and bought sperm. Then I went to a nurse who put the sperm inside my vagina to meet my egg. That’s how you were made.” / At the time I thought I should explain it to Sebastian, who was four. I said the same thing, except, “The nurse put the sperm inside Mami Vicky.”
