Try Dr. Rajeev Sathanandaraja, he is a Paediatric Neonatologist(very few are in the town), very nice and kind with babies and you can take as much time as possible to talk and clarify things with him. You can always reach him on his mobile and he won't ask you to visit him unless it's very much necessary. He goes to Nawaloka, Central, Lanka, Sulaimans & Royal Hospitals.
I highly recommend him, and I used to take my baby girl (1yr & 3 m) to him from the day one.
