How do you honor your child's birth parents in your family?

My birth daughter is too little to understand what adoption is, but she definitely knows I am someone special. There are photos of her and me in her nursery. We visit often, and her adoptive parents are always so thrilled to see me, so she is as well. I can tell they have been practicing saying my name with her. They do the same with their son, talking openly and positively about how much their birth parents love them. It's the little things like these that count.
