I think if you go on the Mama natural website you can edit it before printing
I am using this one (Babylist) and like it! https://www.babylist.com/hello-baby/how-to-write-a-birth-plan#template
Its the downloadable template at the bottom
This one is free and it’s really cool! https://thepositivebirthbook.com/birth-planner/
Parenting Compass has a free downloadable birth plan, it also includes affirmations, reminder of the BRAIN tool and things for partners to remember https://parentingcompass.org/
I got the baby center app and used their birth preferences tools as a guide. You might be able to find some templates googling too.
