That's it really. I only have one sibling, he is two years younger and lives close by with his wife. He has never seemed that interested in my DCs, but I've always tried to involve them both, inviting them over frequently. Recently I realised that THEY never initiated contact, they never asked to see the children, they never invited us over, they never offered to babysit (I only have two very cute and well behaved DCs befor you start imagining horrible gangs!). I started to think maybe they weren't bothered at all about maintaining a relationship. I left my brother a message, basically an open invitation saying you haven't seen the children for a while, just wanted you to know that you're always welcome to come over, we love to see you.
I haven't heard from them in three months, apart from a brief chance meeting at my parents. When I stopped issuing invitations, they didn't bother at all.
It just makes me sad, my children have no other uncles or aunts, to me this was always a special relationship growing up. My DH thinks I should just leave it, he says it's their loss and out DC have lots of people in their lives who love them. But part of me wants to address this with my brother and SIL. Should I?
