Mine is not a plan, but a list of preferences. I acknowledge that some parts of labour I will have no control over! Having hard and fast ideas about how it must happen could be hard if circumstances change during labour, it could lead to disappointment and frustration, right at the time you need to focus! It is better (in my humble opinion) to be educated and have preferences, to give yourself the flexibility to deal with what happens in the manner that suits you best.

Good luck writing up your plan!
