I live in Taikoo my whole life except 4 years in the states for college. Taikoo is a lovely place for families. You can certainly get organic food in the supermarket in Apita or take a 5 min walk to International (more western food) and Justco (greater variety and bigger). There's a huge park that stretches from quarry bay to shau kei wan. You kids can run and play all they want there. Rent is reasonable. Concerning about air quality, itabuse ether than business districts like central and causeway bay, but not as good as Sai Kung/Stanley/any outlying islands for sure. Kornhill (located near Taikoo) is pretty good too. However, the apartments there are smaller and it takes like 10mins (or longer for kids and women with short legs like me :P) to walk to Taikoo MTR station. There are two bilingual kindergartens in Taikoo and more in Kornhill. But as a language teacher myself, I don't see the point of you sending your kid to a local kindergarten. Once you go back to the states, your kid doesn't get to interact with people in Cantonese anymore, she/he will forget the language eventually no matter how fluent she/he is by the time you guys leave. Just my two cents Hope you and your family will enjoy your stay in Hk!
