I must not here omit, so far as relates to Health, to mention Sleeping, and the Circumstances attending it. “Of all (says Mr. _Locke_) which looks soft and effeminate, nothing is more to be indulged Children than Sleep. In this alone they are to be permitted to have their full Satisfaction, nothing contributing more to the Growth and Health of Children than Sleep.” I have already with regard to Infants shewn, that they ought not to be disturbed from their Rest; and even past that Age Sleep affords them great Nourishment. Nothing certainly is more injudicious and unnatural than the Custom many Parents have of keeping their Children up late. If they wish them to be healthy, temperate, or wise, they must create in them a Habit of early going to Bed and early rising. As the many Conditions in Life oblige, or at least lead People to act differently, so it is extremely hard to fix precise Rules herein; but in general, ’till Children approach nearly to Men and Women, they would do best not to sit up to see, much less to eat, a Family-supper at nine o’Clock. Lying on soft Beds is undoubtedly wrong; the _French_ have a good Custom of putting a Matrass above the Feather-bed, which prevents their sinking into a Softness very prejudicial to Health. Soft Beds absorb too much of our Juices, cause a greater Waste than we can spare, enfeeble our whole Frame, and have a remarkable Tendency to give a Pain of Weakness in the Small of the Back, by heating the Reins. Mr. _Locke_, amidst great good Sense, has some Notions a little rigorous, which probably are never followed, nor do they seem altogether needful. He proposes that a Child’s Bed be designedly ill made; that is, sometimes high, sometimes low, sometimes rough, sometimes smooth; for my part, I am desirous to banish every ill-judged Tenderness, every false Fondness; but as I write for the Use of both Sexes, and all Conditions, I cannot confine my Ideas to a Tent or a Cabin. Let Children by all Means lie on Matrasses instead of Beds, for the Reasons already given; let them lie with a Bolster only, and no Pillow, for it is not good for them to have the Head high; let them lie either on one Side or the other, and not on the Back; and let them lie pretty straight in the Bed, yet not fully stretched out, for that would impede the due Action of the animal Functions, and render Sleep less profitable to them. With regard to the Form of their Beds, I think, Decency requires that they be orderly and regular; nor is there any Fear that a Change of Bed will affect them, for most young People sleep sound wherever they are laid.
