Let your Children Sleep Enough.
As sleep is the period for replenishing the system, for restoring the cells wasted by the nervous activity of the day, the period when the processes of digestion reach the final result, by identifying the new nutriment with the system in the place of the waste of the tissues, it follows that children need more sleep than grown persons. Many who might be plump, active, and happy, if given sleep sufficient, are flaccid and sallow, weary and fretful, because they do not get sleep enough to allow the demand of the system for nutrition to be supplied. Children often feel it very hard that they are sent to bed early, while the grown people sit up and enjoy themselves long after they are to bed. If any children chance to read this paragraph, to them we would say: "You need more sleep than your parents, because you have to grow and they do not. You need to use a good deal of the food you eat in growing larger and stronger; if you consume it all in activity, you will not have enough to grow with. Therefore you ought to sleep a good deal, and let the body rest from exercise, if you would grow strong and healthy."
