they dont know any different bro, they were young when we got divorced which is a good thing. My brother is going through one right now. He has 2 girls 11 and 13...they are taking it pretty hard
I was 3ish when my parents seperated and 5ish when they divorced. I honestly never had a good memory of them married. I do think its much easier on younger kids. I was lucky though by the time I was 8 my parents had worked out co-parenting real well.
