I remember having great trouble actually sitting down and writing my birth plan, it was difficult to decide what was important to us and put it into words.
So my birth plan ended up being very brief!
I was adamant I didn't want drugs so stated that I was not to be offered any, if I wanted gas I would ask for it.
I stated that I wanted DH to cut the cord and weigh the baby after the first breastfeed. Also for placenta to be birthed naturally.
I asked for someone to take photos of the three of us together.
I stated I was hoping for an active birth and wished to be left to labour as naturally as I could.
I requested any interventions be discussed with myself and DH (was more concerned with being cut than anything else and would've preferred to tear naturally if I had the option)

In hindsight - was not offered drugs and got through without any.
DH did get to cut the cord and weigh DS and although the midwives let me try I had to have a managed 3rd stage. After everything I'd been through I really didn't care!
No one took pictures of us but I guess they were busy.
I should've had more detail about labour as I was basically left the whole time. Even though the midwife was always in the room she was very hands off and didn't offer any suggestions for the entire 12 hours I was in there. Next time I'll write more!
I almost had suction which was explained at length to us at the time.

Although I didn't mention music or lights, there was soft music playing and the lights were lovely and dim in the room when we arrived.

Good luck! I think in the end birth plans can really depend on who is reading them and in the heat of the moment they can get forgotten about. But if you're having a doula I'm sure she'll be very familiar with yours when the big day arrives!
