no disrespect to your DH, but is he the one going to birth your baby? and why is your MIL even figuring into this conversation? None of her business, IMO (not knowing your relationship with your MIL so sorry if that's out of line) Is she going to be filling his head with how you should raise your child too?

have you looked at getting a doula. He may not be able to support you in getting the kind of birth you want if he's not willing to look at other alternatives. So a doula may help you with your anxiety.
