I'll admit this is 'inspired' by another thread so if anyone wants to report it, feel free.
Despite not being interested in children of my own, I have every sympathy for couples who struggle with infertility, or secondary infertility.
I can also fully imagine why people are excited to be grandparents: squidgy new bundles of joy, all the fun of parenting with none of the bad bits - assuming you live close by. And even if your grandchildren live further away I can imagine how fun it must be to see them grow, change, etc.
So I can understand why someone would be quietly disappointed not be a grandmother/grandfather.
But assuming you had more than one child (and therefore had had the joy of creating and parenting your own family), and assuming you had at least one grandchild to love and spoil, would you really mind if one of your children decided not to have kids?
I am asking because this is a situation I find myself in with my PIL, and I would like to understand their p.o.v.
