So my husband is Bosnian and my son came out white like him lol no brown whatsoever, ppl

Stare at us all the time

and I know they’re looking like hmmmm is that her baby ??? And I have been asked and I simply ignore or say yes and walk off. Should I be offended or no ? And what should be an appropriate response? I often want to show the stretch marks and birth photos like YES this is my son!!! Lol I’m joking about it now, but I do get annoyed and mad sometimes but idc because I love my baby 🥰
