she can convince him that his conduct is a matter of
indifference to her, the victory is won. It is because the child knows
so well that his mother does care that he so often has the upper hand.
It is not difficult to distinguish between a true emotional storm and
the tyrannous cry of a wilful child who demands his own way.

Light and broken sleep is a common accompaniment of a too excitable
and overstimulated brain. The placid child, who eats well, plays
quietly, and does not cry more than is usual, as a rule sleeps so
soundly that no ordinary sounds, such as conversation carried on in
quiet tones in his neighbourhood, have the power to waken him. When he
wakes, he does so gradually, perhaps yawning and stretching himself.
The nervous child may move at the slightest sound, or with a sudden
start or cry is wide awake at once. A hard mattress should be chosen
without a bolster, and with only a low pillow. Flannel pyjamas, which
cannot be thrown off in the restless movements of the child, should be
worn. The temperature of the room should be cool, and the air from the
open window should circulate freely, while draughts may be kept from
striking on the child by a screen. All the sensations of the nervous
child are abnormally acute. Thus, for example, an itching eruption, or
tight clothing, will produce an altogether disproportionate reaction,
and may result in a frenzy of opposition. Especially such a child is
sensitive to a stuffy atmosphere or to an excess of bedclothes. Cool
rooms and warm but light and porous clothing are essential. An
electric torch, which can be flashed on the child for an instant, will
assist the mother or nurse to make sure that the child has not thrown
off all the bedclothing.

Sometimes want of sleep is accounted for by a real want of physical
exercise. Town children especially are apt to suffer from their
limited opportunities of running freely in the open. It is often
considered enough that the child seated in his perambulator should
take the air for three or four hours daily, while much of his time
indoors as well is devoted to sitting. It is necessary for his proper
development that he should have opportunities of daily exercise in the
open. If for any reason this is not always practicable, a large room,
as free as possible from furniture, should be chosen, with windows
thrown wide open, in which the child may romp until he is tired.

It is rare for children of two or of three years of age,
