DD is mixed race - dad Jamaican & mum British. She refers to herself as 'mixed race' rather than dual heritage because she accepts both of her parents are not from a homogeneous background.
She has asked if she were to have a child with someone who was also of the same background - would that child also be 'mixed race' or would there be a better term as both sets of grandparents were the same (dad Jamaican & mum British)
I immediately said no they would be mixed but then I started thinking......what if?
I don't think it really matters, or helps to pigeonhole people into groups. Th child can call themselves what they want - mixed race, half caste, dual heritage... It doesn't matter as long as child is comfortable with themselves. I would avoid even making it as issue.
