You will probably not have any problem from your CW if you tell the children "this is dinner. You don't have to eat it if you don't want it. However, there's nothing else for dinner." You're not withholding food. You've made a reasonable meal and the child has choosen to not eat. Skipping a meal or two will not hurt the child and they will quickly learn that there's a long time between dinner and breakfast.
