The first half Year of a Child’s Life is far the least troublesome to a Mother or Nurse; for after that time Children begin to take Notice, shew they love Action, and where they are well nursed, never are so happy as when they are exercised; and indeed it is scarcely possible to give them too much of it. There should be no Sluggards about a Child, no body that wants either Will or Power to toss it about continually; and from six Months, to a Year and half, or two Years old, it is really a great Fatigue to give it due Attendance. But Parents must remember it is an indispensable Duty; and their faithful Discharge of it will, generally speaking, be amply rewarded by a more solid Health in their Children than can be expected without it; and by having their future Trouble greatly lessened: for how often does it happen that Children for want of due Exercise grow ricketty, become Cripples, or are puny all their Childhood, perhaps their whole Lives; to their own great Sorrow, and to the inexpressible Trouble, Pain, and Expence of the Parents. Rickets is a Distemper extremely common in _London_; but if the Rules already laid down be observed, I dare affirm, it will very rarely be seen. It is not indeed the Design of this Treatise to cure Diseases, but to prevent them; yet as thousands of Children fall into the Rickets in a manner insensibly, often without it’s being once apprehended; I would here not only keep the Attention of Parents awake, but propose a Remedy. Let us then observe, that many Children have all the appearance imaginable of Health, Strength, and Vigor, till about nine Months old; after that Age they begin to dwindle, grow listless, heavy and inactive, which to account for, Parents find a thousand Causes, perhaps all wide of the real. One ascribes it to cutting the Teeth, another to a Fever, a third to loss of Appetite, and so on; when after a Time it proves the Rickets: the Cause whereof is, generally speaking, bad Nursing. But whether this, or any other Weakness produces the Distemper, I earnestly recommend, that it be not suffered to pass unregarded, since much depends upon our early Care. The great and noble Remedy for this Disorder is a Cold Bath; and tho’ the Tenderness of Mothers may make them shrink at the Proposal, yet neither their own Weakness, nor the Child’s Reluctance, must in this Case prevail, especially when I assure them that a very short Time will make the use of it not only easy but pleasant.
