Since so many people were interested in this idea, I thought I would give another follow-up now that's be in place for a while.
We still have not had to introduce the Learning Plate, but Morgan is definitely testing the concept. She isn't eating as many foods anymore, I think, in an attempt to see if we really won't press the issue. It's hard to bite your tongue, especially when you see her leave food she usually tries untouched on her plate. As we stay quiet and continue to disengage, I'm hoping that she starts to try things again. I'm 99% sure this is the strong-willed child testing the boundaries to see if we go back to our previous battles.
I'll keep you posted.
