I try to take a very hands-off approach to eating. I provide healthy options, and it's her job to eat it. If she chooses not to, I guess that's her choice. There will always be a next meal (or healthy snack) and with that comes another option to eat.
It is the parent's responsibility on WHAT, WHEN, and WHERE to feed.
It is the child's responsibility on HOW MUCH and WHETHER to eat.
I have to remember this constantly. I just tried it 100% fully today and it was SUCH a weight off my back.
