i gave birth at Yeung Wo and the 兒科 doc is very patient and detail to follow my son during the stay in hospital. so i feel quite comfortable to consult him. his clinic has a 打針套餐 too (up to 18 months, 打6合1, 智能測試 and some other assessment).... but the package is around 7000.
btw, my son did the hearing test in yeung wo as they have a equiptment to detect the nerves impluses rather to observe the response from the new born. the test costs 1000.
