I was raised that a child shouldn’t be put in the middle of the disagreement of adults. I remember being a kid and if my mother was upset with one of her sisters and I didn’t act cordial to them I would be in big trouble. I agree with this 100 % and try to raise my children to be the same. It’s a little sad when parents make their grown up problems their children problems as well. Adults get over things and kids remember the things that happen as they grow up. Letting kids do this creates a type of personality that holds grudges, a personality in which they learn to take other people people’s problems as their own.
