e of milk sugar, of ordinary brown
sugar, in half the quantity, is of assistance; or of some of the
malted foods (Mellin's food, malted milk, cereal milk) also in the
place of milk sugar.

The substitution of the milk of magnesia for the lime-water as
recommended on page 60 will often be found useful.

To infants over nine months old, orange juice may be given.

_What special modifications are required during very hot weather?_

During the warm season it is well to make the proportion of fat less
than during cold weather. During short periods of excessive heat it
should be much less. The fat is reduced by using 7-per-cent milk in
place of 10-per-cent (i.e., the Second instead of the First Series of
formulas, page 71), or plain milk in place of the 7-per-cent milk in
the Second and Third Series (page 90). At such times also the usual
food should be diluted, and water should be given freely between the
feedings.

_What changes should be made in the food of a child who, with all the
signs of good digestion, gains very little or not at all in weight?_

If the child seems hungry the quantity of food may be increased; but
if the child will not readily take any more in quantity the strength
may be increased by the use of the next higher formula. One should,
however, be extremely careful under these circumstances not to coax or
force a child; for this plan is almost certain to cause disturbance of
digestion and actual loss in weight. A better policy is that of
looking after the other factors in the child's life,--the care, sleep,
fresh air, etc., for with these rather than with the food the trouble
often lies.

_What should be done with infants who in spite of all variations in
the milk continue to have symptoms of indigestion and do not thrive?_

Except inmates of institutions who form a class by themselves, most
infants who receive proper care thrive upon milk if the proportions
suited to the digestion are given. Still there are some who do not.
The nutrition of such is always a matter of difficulty.

If a wet-nurse is available the employment of one is the thing most
likely to succeed, particularly if the infant is under four or five
months old.

If the infant is older, or if a wet-nurse cannot be obtained, some of
the substitutes for fresh cow's milk may be tried. One of the best is
condensed milk, Borden's Eagle brand, canned, being preferred. This is
more likely to agree if the symptoms are chiefly intestinal
