I had a girl in care who was the slowest eater on the planet. I tried everything to get her to hurry, going ahead and having circle time and leaving her at the table, she didn't care, putting everybody to bed, she was still there and didn't care. She kept eating, just very slowly and she wouldn't care if she sat in that seat all day and I just changed her plate from breakfast to lunch to snacktime I swear!

Then I tried just giving her tiny portions and taking it all away when all the other children were finished. She didn't care about that either. Oh well, you gotta do what you gotta do because we have to keep things on schedule! I think you should try a few different things like I did and figure out what is best for you. Of course, I always told the parents everything I was doing so they knew how much their child actually ate every day and why or why not.
