Living near or on MTR stations is convenient, and also near large shopping malls convenient too, since I assume it'll be a while before you venture to local foods. Hong Kong Island is out of the question due to distance. Kowloon Tong is a nice neighborhood with a good amount of expats etc. Especially the quiet low density neighborhood. If I was your husband I would choose to live closer to work to avoid the commute. Daughter at least can avoid the traffic when she is getting off school. Gold Coast is not very convenient though and you might have to consider driving. If it was your choice I would say a central point like Kowloon Tong is good since it's convenient for all parties and is close to a lot of things.
