I really feel you on this, especially as a first-time mum trying to get everything sorted before your EDD. I don't have direct experience with Dr Vanaja or Dr Biswas personally, but a friend of mine delivered at NUH with Dr Vanaja and said she was quite patient, explained everything clearly, and her stitching was neat with no issues at all. It might be worth booking a consultation with her just to get a feel for her bedside manner before you commit, since that one visit can tell you a lot.
