About Mia's birth by Caesarian section, Kate says, "I spent my life being told I have these fantastic child-bearing hips, so I breezed through this pregnancy, merrily eating and gaining 70 pounds, and came to the birth just very excited and really looking forward to it. I never thought about a Cesarean section. It just didn't occur to me. After 37 hours, they came and said, 'We're going to have to induce you.' And even that didn't work! And then the C-section."
