I think I'm going to but I'm not sure if I'm mad to do so. In my case, it's because a very good job has come up and it's a short-ish contract where it would be very very awkward to take maternity leave, at least initially. The idea is that if I take this job it will eventually lead to a career that is far more flexible when the kid(s) are at school so in theory it's worth delaying TTC by 6 months or so. But, I'm absolutely desperate for another baby (my DD has just turned one) and I'm 36 already. Am I completely mad to delay TTC - especially at my age (I got pregnant first month last time but know there's no guarantees for the second baby)? I just wondered if anyone out there is or has been in a similar situation - and what did you do?
