OMG,
I went to stay with my IL's last week with dd's, we had a fab time but after a few drinks my FIL told me (in context of a conversation not out of the blue) that they had an abortion when my MIL was 40.
Said they did it as they were worried for heath of baby with MIL being 40 (although she she 35 when she had SIL), they then told me they had had no tests or anything, so didn't really know if even increased risk of any helath probs.
My PIL are very wealthy and had there parents aat home to look after children, both worked full time. Later in the same conversation the fact that the child would still have been at uni when FIL retired was mentioned.
Thing is I would really not like dh to know this and I don't really want to carry round secrets. I wish they had not told me, I can't help looking at them with less respect now, I know it was their decisions but they know my opinions and that we would love more children but are not able.
