It is working for potty training, right?
So here is the plan, I make a chart with labeled slots that she can read on her own, for example:
Chocolate milk (Pediasure)
And send her over to check it several times a day and ask her if she wants to have one and earn a sticker. If she eats and drinks it all, she'll be doing pretty well nutritionally from what I estimate, although I'm still waiting on the exact numbers.
I hope it will give her a bit of control, which she seems to crave, and a bit of incentive, which she seems to like. We can handle it as casually as this potty training thing, hopefully taking a bit of the underlying struggle away.
Maybe. Maybe not.
But it can't hurt to try, can it?
