Your DGD may just need to see herself reflected more in everything around her. It really depends on how everyone around her responds to her. Does she live within a bi-racial family or is she the only family member who has darker skin?
I agree it may not a deep seated angst but maybe an observation that she loves mummy and wants to be her. Neither of my DDs or DGDs look like me or their mothers, we all have very different hair and colouring.
However do not completely dismiss the idea that she has picked up on any negative attitudes somewhere. It would be awful not to acknowledge that and to reassure her.
