What do i do? How do i get my dad to stop making snife remarks?

So im currently 33 weeks pregnant and I honestly feel so alone at the minute. Ive got my dad making snide remarks about my partner constantly, other day i went out with my mum for coffee and we went back to my mum and dads house so my mum could pick my dad up and then drop me back off at my house so they could go out afterwards. When they dropped me off my partner was outside cleaning the car and my mum said “ehh, if he’s quiet then leave him to it” and my dad just said “or just leave him” and my mum turned round and said “hes only joking dont worry” but it honestly dosent feel like a joke because hes always saying that sort of stuff about him. I haven’t told my partner what he said because my partner dosent like my dad anyway, ESPECIALLY at the minute aswell because my dad also spoke to me like crap about something and my partner told me he was about ready to say something. Im also just trying to keep the peace at the minute because as i said before im pregnant so i dont want to be stressing out about stuff but not talking to anyone about it is just making me stress anyway.

We also want to get our daughter christened with the same person who christened my partner, im not christened so i said that when it comes to this then we do what my partner wants. The only thing is its down in London and we live 3 hours away which is fine with me, i like my drives out but my dad started getting arse on because he doesn’t like London and i said well its where my partner got christened and some of his family still live in London so it makes sense doing it down there and he said yeah maybe but your family lives up here. Like he thinks everything should revolve around them and he dosent want to drive 3 hours to see his grand daughter get christened. But me and my partner are talking about moving down there, we haven’t told anyone yet until we know for sure we can do it but im abit scared im never going to see my family or they are just going to make me or my partner feel bad about moving their grand daughter away. But obviously we want whats best for our daughter, my partners mum died in the town where we currently live and living here has gave him very bad mental health problems to the point he dosent leave the house or answer phone calls from anyone so we both think it’ll help his mental health and itll help our relationship which in future will be best for our daughter.
