I have a friend whose baby is nine months older than Rebecca, and recently she and her husband decided to do a romantic getaway before their next baby comes. That sounds nice, I said, whenever she mentioned it. Was I really oblivious that she was nervous about leaving her daughter? I really was. Despite having been a stay-at-home parent for over a year now and having read a lot about other mothers’ experiences, I apparently still haven’t gotten it through my head that leaving your baby can be hard to do, even when your baby is more like a toddler and even when you’ve got someone you trust and who isn’t unduly put out to look after her. Lots of people leave their babies every day, so how bad can it be?
