So just to add my 2cents in to this we’re currently in the process of both NCT and our NHS(hypnobirth).
Whilst I’m enjoying both the detail covered on NCT has put both me and my wife at ease. The NHS classes are more focused on first and second stage of labor.
With the NCT we’ve been offered additional classes to cover a few more topics in detail.
Class size differs between the two there is twice the number of couples in the NHS.
