On my 41st birthday, I found out I was 6 weeks’ pregnant, and my life was turned upside down. I had never been especially interested in having a child of my own; I was quite happy with the idea of being the indulgent, eccentric aunt. The fact that our daughter exists is a development that is forcing me to question everything I thought I knew about myself. This is my journey, and hers too. There may be projectile poo involved.
