Mine have never met my parents and never will. They ask and I give them age appropriate information. I think this is one of those times when it's our job to make the right decision for them, and their safety even if they don't agree with us at the time.

DD & DS have lots of family that love them, even if they aren't blood related. Lots of aunts and uncles and even pseudo grandparents. I don't feel they miss out because of my choices. I think they have gained because of them.
