My kids only have one set of living grandparents and they are a little confused about where Daddy's parents are??? To add to it, one of his brothers has a wife who for some reason seems to dislike me, why?? I have only met her twice!!! so needless to say we don't see them..so thats kind of taking out one side of the family for them which is sad as they have cousins not too much older than them.. The other brother we do see.. but his kids are older and are living overseas etc so we don't see or hear from them at all.
What can you do??? Maybe you have to make sure there is a family history/tree to pass on... if nothing else it is interesting to see family groups and names etc. Plus it is very easy to lose that over a short time frame.

It could be one of those situations where it might just be better to imagine it would have been a great life having had them in it...but like a lot of people say you can choose your friends but not your family.. and they choose to do just that, becasuse they have big conflicts amongst themselves, and it easier/better for everyone to stay away.

Goodluck Maz, I can imagine it would be difficult always wondering.
