In terms of getting her to eat over that 6 year period - no power struggles ever. Especually at the beginning we passed no comment on how much she ate beyond "Wow you were hungry today!" if she ate well. As she got older and more reasonable we made progress to enforcing having a taste of new things (and earned her trust that we never made her eat more if she didn't like it) or eating at least a few bites if foods we knew to be acceptable to her (yes you MUST eat some carrot today). We offered primarily foods that there was some hope in hell she might eat and always had something on offer she WOULD eat. We rarely offered food that was clearly never going to be eaten (except in addition to safe foods).
