Christmas lunch, you eat what you like. Nye had his normal lunch of croissant with nutella, carrot, cucumber, apple and celery, I had salad with bonus cheese because it's Christmas. We had pasta for dinner. We all ate lots of chocolate. There is little benefit to insisting that a child eats a large portion before pudding, beyond teaching them to eat more than they want. Give small portions and reward. they are more likely to eat a variety that way.
