Can anyone recommend a good paediatrician in KK hospital?

I just thought that since KK hospital is a government hospital, they are more professional and cheaper (subsidised).

I am currently bringing my baby to a private paediatrician (who is quite popular) who is attached to Thomson hospital. But i just feel his advice always half-half (neither her or there) and if there's anything, he will refer to Thomson and the bills are freaking expensive!!
