Roslyn I think it is absolutely your decision, but I am personally only having people in the labour ward with me who can help ME, not just 'watch' the birth. I agree with Kelly in that more people could actually hinder your progress, but since this isn't your first birth I am sure you know how you will react. The other thing to think about is, you are not comfortable with him seeing your girly bits, and that is where all the action is, so there is probably not much for him to see otherwise.
Anyway, best of luck in your decision!
