I haven't personally seen Dr Ee, but a friend of mine brought her child to KKH and mentioned that the doctors there are generally quite thorough and patient with parents' questions. That said, experiences can vary depending on the specific doctor and even the day, so it might be worth posting again to see if anyone has seen him directly. If you are keen, you could also call KKH to ask a bit more about his specialty focus before booking, just so you go in feeling prepared.
