Birthing position

Hello mummies!!! I am subsidies KKH PT , any idea if they allow our own birth position? Cuz i am thinking to do natural and unmedicated& ive see most mums recommend not doing on the back position during labor, any mom here has successfully labor natural and unmedicated ? Any tips and best position for FTM ? ☺️ #advicepls #firstmom #firsttimemom #firstbaby #FTM #pleasehelp
