Usually by the second month if training is begun early.

_What is the best method of training?_

A small chamber, about the size of a pint bowl, is placed between the
nurse's knees, and upon this the infant is held, its back being
against the nurse's chest and its body firmly supported. This should
be done twice a day, after the morning and afternoon feedings, and
always at the same hour. At first there may be necessary some local
irritation, like that produced by tickling the anus or introducing
just inside the rectum a small cone of oiled paper or a piece of soap,
as a suggestion of the purpose for which the baby is placed upon the
chamber; but in a surprisingly short time the position is all that is
required. With most infants, after a few weeks the bowels will move as
soon as the infant is placed on the chamber.

_What advantage has such training?_

It forms the habit of having the bowels move regularly at the same
hour, which is a matter of great importance in infancy and makes
regularity in childhood much easier. It also saves the nurse much
trouble and labour.

_Should a child sleep in the same bed with its mother or nurse?_

Under no circumstances, if this can possibly be avoided. Very young
