How can it be obtained?  A young baby usually gets its exercise by screaming, waving its arms, kicking, etc.  It is a good plan to let baby lie in the center of a large bed, and with his long skirts drawn up, allow him to kick his little legs about for twenty or twenty-five minutes twice each day or one-half hour once a day.  His clothing ought to be loose for this exercise.  If the room is all right you can remove all clothing except his shirt, stockings and napkin; change his position sometimes and let him lie on his stomach for awhile.  Of course this exercise cannot be taken after a meal and before the fourth month.  Take a large clothes basket, put a blanket and some large pillows in it and prop baby up in a half sitting position for a little while each day, beginning with fifteen minutes, then one-half hour, and you can also at this time (fourth month) play with baby for a short time every day, but never just before bedtime, and the best time is just after his morning nap.  Do not toss him in the air to make him laugh or crow; he is too tender and delicate for that.  When baby is older and in short clothes, place a thick quilt upon the floor and allow him to tumble as he will; a fence two feet high which surrounds a mattress, makes an excellent place, or a box for this young animal to exercise his arms and legs without danger of injury.  Before you put baby to sleep at night give him a warm sponge bath with a fresh band and shirt and he will sleep.

When, if ever, is crying useful in a baby?  The cry expands the lungs of a new-born baby, and he should use his lungs a few minutes daily in order to keep them well expanded.

How much crying daily is necessary?  Twenty to thirty minutes is not too much.

What kind of a cry is it?  Loud and strong and infants get red in the face with it.  Some call it a scream.  It is exercise for baby and necessary for its health.

When is the cry abnormal?  When it is very long and too frequent.  It is not strong, but rather of a moaning or worrying nature or only a whine.

What causes such crying?  Habit, temper, pain, hunger, illness.

What is the indulgence or habit cry?  This is the cry of infants who cry to be rocked, or carried about, for a bottle to suck, etc.

Temper cry?  This is loud and strong and is usually accompanied by kicking, stiffening of the body, bending backward and is usually quite violent.

Pain cry?  This is generally strong, sharp and quick, but not usually continuous, the features contract, legs draw up and the baby plainly shows symptoms of distress,

Hunger cry?  This is a continuous fretful, pitiful cry, not strong and lusty,—­baby looks hungry.

The cry of illness?  This is moaning, fretful, easily aroused to crying.  This can be distinguished even from a little distance before seeing baby, if you have heard it once.  A baby who cries to get things stops when he gets them.
