The daily outing secures them better appetites, quiet sleep, and
calmer nerves. Let them be properly clothed and protected in their
carriages, and all weathers are good for them.

Children who take their naps in their baby-carriages may with
advantage be wheeled into a sheltered spot, covered warmly, and left
to sleep in the outer air. They are likely to sleep longer than in the
house, and find more refreshment in their sleep.




SUFFICIENT SLEEP.


Few children in America get as much sleep as they really need. Preyer
gives the record of his own child, and the hours which this child
found necessary for his sleep and growth may be taken for a standard.
In the first month, sixteen, in full, out of twenty-four hours were
spent in sleep. The sleep rarely lasted beyond two hours at a time.
In the second month about the same amount was spent in sleep, which
lasted from three to six hours at a time. In the sixth month, it
lasted from six to eight hours at a time, and began to diminish to
fifteen hours in the twenty-four. In the thirteenth month, fourteen
hours' sleep daily; it the seventeenth, prolonged sleep began, ten
hours without interruption; in the twentieth, prolonged sleep became
habitual, and sleep in the day-time was reduced to two hours. In the
third year, the night sleep lasted regularly from eleven to twelve
hours, and sleep in the daytime was no longer required.
