The milk itself ought not to be heated over the fire, [Footnote: It now and then happens that if the milk be not boiled, the motions of an infant are offensive; _when such is the case_, let the milk be boiled, but not otherwise.] but should, as above directed, be warmed by the water; it must, morning and evening, be had fresh and fresh. The milk and water should be of the same temperature as the mother's milk, that is to say, at about ninety degrees Fahrenheit. It ought to be given by means of either Morgan's, or Maw's, or Mather's feeding-bottle, [Footnote: See answer to Question 24, page 24.] and care must be taken to _scald_ the bottle out twice a day, for if attention be not paid to this point, the delicate stomach of an infant is soon disordered. The milk should, as he grows older, be gradually increased and the water decreased, until two-thirds of milk and one-third of water be used; but remember, that either _much_ or _little_ water must _always_ be given with the milk. The above is my old form, and which I have for many years used with great success. Where the above food does not agree (and no food except a healthy mother's own milk does _invariably_ agree) I occasionally substitute sugar-of milt for the lump sugar, in the proportion of a tea spoonful of sugar-of milk to every half pint of food. If your child bring up his food, and if the ejected matter be sour-smelling, I should advise you to leave out the sugar-of milk altogether, and simply to let the child live, for a few days, on milk and water alone, the milk being of _one_ cow, and in the proportion of two-thirds to one-third of _warm_ water--not _hot_ water, the milk should not be scalded with _hot_ water, as it injures its properties, besides, it is only necessary to give the child his food with the chill just off. The above food, where the stomach is disordered, is an admirable one, and will often set the child to rights without giving him any medicine whatever. Moreover, there is plenty of nourishment in it to make the babe thrive, for after all it is the milk that is the important ingredient in all the foods of infants, they can live on it, and on it alone, and thrive amazingly. Mothers sometimes say to me, that farinaceous food makes their babes flatulent, and that my food (_Pye Chavasse's Milk Food_) has not that effect. The reason of farinaceous food making babes, until they have _commenced_ cutting their teeth, "windy" is, that the starch of the farinaceous food (and all farinaceous foods contain more or less of starch) is not digested, and is not, as it ought to be, converted by the saliva into sugar [Footnote: See Pye Chavasse's _Counsel to a Mother_, 3d edition.] hence "wind" is generated, and pain and convulsions often follow in the train.
