With 4 young children, my wife and I try instill simple family rules that hopefully help them become kind and friendly children to grown ups. Our sign in our house gives us family advices for our kids to be kind and do well in life while enjoy life. I also think parents as me and wife show our love and kindness values toward each other will reflect on our kids on how they treat each other's as sibling, family members, friends, and people they meet in life.
