Advice for a white mom with mixed race daughter

My daughter is biracial. She is black, white, and Asian. I am her mom and I am fully white. We have the same hair texture and look identical in the face, the only difference is our skin tones.

I am white... like WHITE. I’m very pale and she is not pale at all. She has a way deeper skin tone than me. Her skin tone is very deep and island-y. Her skin tone is very similar to Rihanna’s. Maybe even a little deeper in the summer time.

She is 4 and she’s starting to really notice the difference in our skin tones. She’s made comments about how I’m a white girl before but she also kind of acts disgusted by it. And today we were at the pool and she met another mixed race child but her mom was “brown like her”

She seems to focus on the fact that the daughter and the mom had matching skin tones and I don’t have her skin tone and she wishes I would put spray tan on to be brown like her.

I know she feels confident in her skin tone because she constantly talks about how beautiful it is and I always tell her how beautiful her skin is. I love that she feels that way but it makes me sad that she hates that I’m white. She really wishes I would just put tanner on to be like her but I can’t do that.

What can I do?
