Congrats on your 2nd pregnancy! My friend went to Dr Arundhati Gosavi at NUH and said she was really reassuring and had very good bedside manner, especially when my friend was anxious during her third trimester, so if you're the type who needs a doctor who is calm and patient, she's a good shout! Hope you find someone you're comfortable with, that really makes such a big difference throughout the whole pregnancy journey!
Prof mahesh choolani at nuh is great for high risk. also dr arijit biswas who is an advocate for natural delivery. dr anita kale at nuh is also really amazing. Doctor Citra at NUH is also very experienced with VBAC. Go with any of these and you won't regret.
