answer:Of course you can, and I hope you do. Dear Abby once answered a question from someone who, as I recall, didn’t want to include an adopted child or maybe a stepchild in a family photo. Abby said something like “It doesn’t matter how they got to be family. They’re family now.” I would take her advice. People who treat others or get treated by others as if they were members of the family are lucky, in my opinion. Pedigree is irrelevant. I have an adopted cousin who belongs to another ethnicity. She’s still my cousin.
