If shooting indoors in a room with a white ceiling, think about using flash with one of these attached:

I get excellent results with it in those circumstances. The flash essentially becomes part bounce and part forward radiating, with very soft modeling.

It works best with a flash with auto setting or TTL. Otherwise you have to guesstimate the correct setting or use a flash meter.
