Doc,
very interesting story!

I have 3 kids, 5,3 and 1yo. The 3 of them love meat so far, no questions asked and the older 2 know that meat in their plate, whether chicken, beef, venison, pork, was a living animal. No problems with it.
Although not quite like your daughter, they did go through a no milk drinking phase a few months ago. Mom and I did not fight it, we would offer it, and that's it. They went through gallons of yogurt and cheese during that time so no problem. Recently they went back to their milk drinking ways.
Hopefully I can get go out hunting this year and get some venison for the table.
