Parents of biracial kids

While reading the novel i have noticed the struggles of both parents regarding how they identify with their kids because of their mixed ethnicity. it is most obviously very difficult for Deck, he claims to not see Birdie as lighter skin but then treats her like she is not truly her daughter. I feel that it would be very difficult for parents of biracial kids. They cannot identify racially with their children and that must be hard. The kids may receive some form of white privilege that they may never have experienced. The parents could also be approached like Deck is at the park and questioned about his children. I think that it would be very difficult to deal with these and other issues. Also, parents of biracial children would not have gone through the same struggles that their children will as far as racial identification and a feeling of not belonging. That must be difficult for them
