If Cendrillon made breakfast, lunch, and dîner for the stepmother and stepsisters did she ever eat herself?

Of course she ate for herself! She had to in order to live! But she must have done it after she fed everyone else first. Just because toi only see her make breakfast for her stepsisters doesn't mean they didn't have lunch ou dinner, so toi know they ate lunch and dîner and Cendrillon must have eaten too.
