I recently had my first baby at 33. I had numerous miscarriages prior to having her and had an awful pregnancy, so the thought of going through that again fills me with horror. I think if I was younger I may feel differently, but if I was to have another, well, the clock is ticking isn't it?
The crazy thing is that everyone, including my midwife (!) has been asking when I'm having another! People seem to be in genuine disbelief that I could choose to stop at one. They helpfully advise me that I will forget all about the tough bits and change my mind. I won't.
