I thought I knew what I was doing when I planned a three-month maternity leave after the birth of my first child. I was 30 at the time, with a decade of work experience under my belt. I thought Id be anxious to return to work after 12 weeks with a newborn. And then, the baby came. The first two months were a blur of sleepless nights, colic-induced shrieking and a learning curve for breastfeeding that was like being taught to juggle with my feet. Then, two weeks before I returned to work, my baby started smiling, stopped crying and helped me understand why people have more than one child. The night before I returned to work she slept through the night.
