Dr Zhang at Paddington Medical - she is very good with children! calming clinic environment also, Simpang Bedok, right beside Giant! not a PD, but a very calming and detailed GP! better than some PDs actually!
For parents searching for PDs, do try out my mobile app PdGoWhere to search and locate available paediatricians. Full disclosure: App development is purely a hobby and the app is free and not for profit!
