Should I let my mother see my son?

I have an almost 2 month old son whom I think is absolutely beautiful. I am mexican and my husband is white. My son has a lot of his fathers features. I took my son to my mother's house and while we were there, all I got were remarks on how "white" my baby is. My mom just commented on how bald my baby is, even though he has hair, though "not as much as my full mexican" nieces (moms own words) She called him a fat little white boy and she was just saying how he is so much bigger than my sisters daughter who is a week older than my son because he has "that white gene" in him. Later that day, she looked at him all weird and turned to me and said "do you really love him?" I couldn't believe she's ask me that, as if Wouldn't love him because of the way he looks. I do not think I will ever take my son back to my mothers. I don't want to keep hearing all these remarks on his appearance. But I also don't want him to grow up not really knowing his grandmother. I don't know what to do.
