DNA testing

I’m currently pregnant and my bf says his fam will want a dna rest once the baby is born Is it bad that I’m mad about that like he knows I’ve been faithful to him but he says that’s just how his fam is and that it will happen cus they want to make sure . Also a batism for the baby cus that’s what his mom will want yet I don’t have a say in that even tho I don’t believe in it. What should I do bite my tongue and go thru with it or ??
