I need help ☹️ (please read)

So of course it’s getting closer to that time and that means people are going to start adding their opinions in about the baby especially grandparents. My childs father doesn’t really stand his ground against his mother so I feel like it’ll make things difficult between us. They’re African so I allowed my child’s father to pick her middle name and she has his last even though the way I was taught, if you aren’t married your baby should have the moms last name anywho she asks why isn’t the baby’s first name African and I had to keep saying over and over that she has a middle name that is African and that me and him previous picked out her name before she came about and I didn’t want to say it to avoid conflict but my child isn’t full blooded African so it’ll be things that they do according to their culture that I won’t agree with or follow through with and I feel like she had a chance to do that with her 4 children so with my child I want to do things me and his way plus she’s just TELLING me what she’s gonna do vs asking. So then she and him and discussing back and forth (without me HER MOTHER in the conversation) talking about changing her name and instead of him putting his foot down and telling her it’s set in stone, he’s feeding into it. Anyways then she does to say that in their culture they have to give the baby a bath but I already told him before that me and him should give her, her first bath because it’s our first child after 4 miscarriages and i want us to have every first moment and he agreed but im reluctant to bring it back up to him because i don’t wanna argue just like I told him I didn’t want anybody else kissing her because of monkeypox and covid and he thinks i’m being ridiculous, i haven’t had covid and i’m terrified of my child getting it or anything else. Any tips on how to stand my ground? How can I talk to my child’s father and approach the situation without conflict? When would be a good time to talk to him again about it?
