in digesting cow's milk, it is advisable to begin the use of other
food at three or four months or even from the outset.

_What is the first thing to be used with milk?_

Farinaceous food in some form, usually as a gruel.

_How are these gruels made?_

They may be made directly from the grains or from some of the prepared
flours (page 149). The flours are usually to be preferred as being
more simple of preparation.

_How should they be used in making the food?_

They should be cooked separately, rather than with the milk; when the
food is mixed, they take the place of a portion of the water in the
formulas given on pages 70 and 71.

_How much of the gruel should be used?_

If it is prepared as recommended on page 149, it may make according to
circumstances from one sixth to one half the total quantity of food.

_Which of the farinaceous foods are to be preferred?_

Those most used are barley, oatmeal, arrowroot, and farina. There is
not much difference in their nutritive value; oatmeal gruel is
somewhat more laxative.
