Hi Miao - Our daughter who is now 4 months old, has seen Dr. Leung since her birth at the Adventist. We found him to be very positive, energetic, and great with crying and fussy babies! His clinic has a package available for all vaccinations which also includes a discounted consultation fee for each visit that is related to the vaccination. I think it works out to HK$510 for each visit plus the vaccination. The package we purchased cost about HK$11,700 but includes all her developmental checks and vaccinations up to 18 months of age. You must pre-pay the full package but you get 15% discount and 10% off on all consultations. It's hard to buy a package up-front, but we really liked Dr. Leung so for our first visit out of the hospital, we purchased it. His regular consultations for sickness are $600, if I recall correctly. BUT, he is always available to answer your questions by phone or email. He's very quick to answer either one, which is great. Saves you the consultation if you're just worried and don't think you really need to see him. I even called him once at midnight because my daughter was spitting up an unusual amount of milk and he was still very calm and helpful despite the fact that I woke him up. We highly recommend him!
