Ideas about convincing my husband?

Iy

Sorry this is a long post.

I grew up using natural and holistic remedies my whole life, along with going to the regular doctor if needed. I have celiac disease so my body has a hard time getting nutrients from the foods I eat. I'm now 31 weeks pregnant and I'm thinking about the future with my little boy. My husband doesn't have any experience with holistic or natural remedies, so he's not too keen on letting me use this type of medicine on our son. My husband told me today he hopes our son isn't a cryer. I told him they really only cry and fuss when they need something or are in discomfort and that we'd take him to the pediatrician first to see if it was a quick fix. If not, I wanted to take him to the nutritionist/iridologist that I grew up going to see. My husband doesn't want anything to do with him or anything natural and I'm having a hard time trying to convince him our son isn't going to die if we do some natural supplements along with the pediatrician. Do you ladies have any ideas about how I can help him be more open?
