Mary needs sugar

The fine print in the Note to Mothers -

"Exhaustion may be dangerous - especially to children who haven't learned to avoid it by pacing themselves. Exhaustion opens the door a little wider to the bugs and ailments that are always lying in wait. Sugar puts back energy fast - offsets exhaustion. Synthetic sweeteners put back nothing. Energy is the first requirement of life. Play safe with your young ones - make sure they get sugar every day."
