Dr Adelina Wong

Would like to know any mummies been with Dr. Adelina Wong before. How was the experience? Also there's a set of docs (inside pages are stuffs like vaginal delivery/epidural/c-sect/emergency c-sect/episiotomy etc to be sign before going into labour right.. But signing does it means agreeing or during necessary changes need to switch to the other or do anything they will still check with us if we are OK to proceed? Will Dr. Wong follow/respect our birth plan? As I would prefer not to have episiotomy perform, emergency c-sect or to take epidural unless it is life threatening or baby is in stress etc
