I'm not sure which one accepts, but you can try Ampang. I didn't do gentle birth, but during my first n 2nd labor it was almost gentle birth (I still had to push) as they did not offer me any epidural or gas, and I remember the nurse's exact words "you can sit/stand whichever position you want" so I guess that's good enough for me. And plus there were no nurses at all involve during my 1st labor, just a doctor n my husband. My 2nd birth there were a lot of nurses because it was 10cm when I was still in ward, so it was kind of a rush n had to be managed by many. So I think you can prolly ask if you want gentle birth.
