Gas & air or epidural for labour, which is better?

Epidural: I don't know if by gas you mean anesthesia. If so epidural is safer you are conscious participate in the delivery, it can cover a C-section as well and your newborn will have less medication transfer to them.

Sit down with: anesthesiologist or OB doctor to discuss the pros and cons in detail. I cannot cover the necessary considerations with a 400 character limit. I hope you have a healthy baby either way and that all tuns out well.
