Racial comments that really make me mad!!! 😡

So idk if this has ever happened to anyone, I have two children from a previous relationship (their biological father has never really been in the picture). I met who helped me get through a lot I was going through at the time, super polite and well mannered gentleman who treats my children as his own, a true blessing to us.He is Black African and we have a lot of friends in common as well as I know his amazing mom and family, who treat me really well, most of his friends are great but some are kinda rude and just annoying to be around. But since recently finding out I was pregnant and telling a few of our friends and that we are having a baby, I have gotten none stop comments about what shade of dark my baby is going to be!! Like wtf is it any of your concerns, they act like u didn’t know my man is black and it really bothers me because it’s my baby. Should I say anything to those people or brush it off? Btw my mom is a monster as well and has even said (your kids are all going to be different shades) like tf
