I always thought I’d have two kids, and that would be plenty. I focused on establishing my career as a magazine editor and author and didn’t have my first child until I was 35. Somehow, after I had my second, I thought, “three would be great.” I had no issues getting pregnant again (and no difficulty with fertility prior to that), so I had my third child at age 40. After about two years, my husband and I decided to try for a fourth baby.
