In a bad case of thrush, change of air to the country is most
desirable; the effect is sometimes, in such cases, truly magical.

If the thrush be brought on either by too much or by improper food; in
the first case of course, a mother must lessen the quantity; and, in
the second, she should be more careful in her selection.

_What NOT to do_.--Do not use either a calf's teat or wash leather for
the feeding-bottle; fortunately, since the invention of India-rubber
teats, they are now nearly exploded; they were, in olden times,
fruitful causes of thrush. Do not mind the trouble of ascertaining
that the cooking-vessels connected with the baby's food are perfectly
clean and sweet. Do not leave the purity and the goodness of the cow's
milk (it being absolutely necessary to feed him on artificial food) to
be judged either by the milk-man, or by the nurse, but taste and prove
it yourself. Do not keep the milk in a warm place, but either in the
dairy or in the cellar; and, if it be summer time, let the jug holding
the milk be put in a crock containing lumps of ice. Do not use milk
that has been milked longer than twelve hours, but if practicable,
have it milked direct from the cow, and use it _immediately_--let it
be really and truly fresh and genuine milk.

When the disease is _severe_, it may require more active
treatment--such as a dose of calomel; _which medicine must never be
given unless it be either under the direction of a medical man, or
unless it be in an extreme case,--such as dysentery_; [Footnote: See
the Treatment of Dysentery.] therefore, the mother had better seek
advice.
