how old is this kid. I offer breakfast. My rule is that if you come after breakfast then its the parents responsiblity to feed them and the child will have to wait for the next meal. I don't charge extra but I also don't make anything big or expensive. Right now my group is really into dry cereal, I have no idea why but thats what they want (they are all 2 or 2.5 yrs old). I would just let the parents know that you will not be providing breakfast no more if you find its too hard.
