Hi Jenny,
The Chengdu International Women’s Club should be able to help you further since most of them are mothers with (young) children.
The imported brands are available at the big supermarkets like Auchan, Carrefour, Ito Yokado… so no need to worry about that.
For vaccinations, you can go to Global Doctors or Parkway but there are also very good doctors at 2nd West China Hospital and Sichuan Provincial People’s Hospital who can speak English.
For housing, please take a look at http://www.myhouseinchina.com. We have a wide selection of apartments and (town)houses in the South of Chengdu in all price ranges. Don’t hesitate to contact our bilingual staff for more information.
Cheers!
