Can I give birth at NUH?

I don't think you can switch over like that, because your medical records and all your antenatal care are already with KKH, so it'll be messy to transfer everything to NUH at delivery. Best to just confirm directly with your KKH gynae or the hospital admin what the process is, but usually you deliver where you've been seeing your doctor throughout pregnancy. My friend tried to do something similar and it got complicated, so might save you the hassle just to stick with KKH.
