NUH gynae experience

I haven't personally seen those three, but I know quite a few mums who've switched to private around the same gestation as you and they all say the key thing is finding someone who listens and doesn't rush you during appointments. Since you're already at 29 weeks, I'd suggest calling their clinics to ask about availability and how they handle third trimester care, because some gynaes have tighter schedules closer to delivery. You might also want to check if they deliver at the hospital you prefer and whether their fees fit your budget, since private can vary quite a bit. If you have friends at your polyclinic or from antenatal class, they might have direct experience with one of them that could help you decide.
