What I got from the original post (and a few subsequent ones) was that the 2nd pregnancy was planned to co-incide with the first lot of maternity leave so that she wouldn't have to go back to work.
Not so much an accidental pregnancy.
Of course, an accident is usually an accident. I don't object to women having children in general. However as a woman trying to be taken seriously in the world of aviation (or anything else for that matter) I sympathise with the general public on this topic.
