Getting hubby onside with hynobirthing?

Hello lovely ladies! 🌞 Last week hubby and I found out that we’re about 4 weeks pregnant. It’s our first so everything is new for us. We’ve been trying for a few months, so I’ve already read up on hypnobirthing and decided this is the best approach for me and baby. Hubby however, doesn’t know much about it. He’s still at that stage where he thinks it’s not scientific and it’s some weird, hippy stuff that could potentially put baby in danger. Completely understandable cos I also had no idea before I properly looked into it myself! Did anyone else have to educate their husband/boyfriend and eventually win them over? If so, any tips would be welcome! P.S. I read Siobhan Miller’s book and have another to go. And I became obsessed with positive birth story videos a few months back! 😂 So I’m still educating myself lol
