I really feel badly for those of you whose children receive such ignorant treatment. My parents also favored other grandchildren over my kids and my family basically ignores my adopted children. Now I'm going to talk about the other side of the coin. I have 2 grandchildren 27months and 23 months old. Both live within 10 miles of us. Due to our disabled children it is very difficult for us to get out. DD#1 calls us every few weeks and brings DGD to visit a few times a year. DD#2 brings DGS to our home at least 3 days a week to babysit (made same offer to DD#1). Do I favor DGS? No. Do I know him better and have a better relationship? Sure. I am not saying that you as parents caused favoritism but at some point I will bet DD#1 will accuse us of favoritism.

Just wanted you to know the other side. Karen
That is not always the case though! On my side I mentioned my Mom favors my DD's, we live over 5 hours away from her and have since the girls were born. My brother and SIL have lived mostly in the same town as my Mom for 20 of the last 25 years.
Even with the distance my Mom has spent more time going to activities for my DD's. She will drive all the way across the state to watch a play (drove down Thursday afternoon, went to play and went home Friday), go to a birthday party, see a concert, etc... but she can't drive across town for the local grandkids. She has missed countless baseball games, basketball, football, plays and programs and yes, even birthday parties!
I can honestly say to you that the only time my Mom will go to one of my brothers kids activites is because
I am in town and going with my girls. How sad is that?
My brothers kids have never spent the night with Grandma either, even though they all live in the same town, unless we are there and I invite them to stay with us at Grandma's so they can spend more time with their cousin's. Grandma doesn't like it either, she'd rather just have my girls there.
Each summer my Mom wants DD14 to come spend a week, but as soon as I mention her getting together while she is there with her cousin who is 3 days older, my Mom drops the subject.
So, even though she is closer to them, she is not "
closer" to them.
