《葛氏肘后》∶小儿新生三日，应开腹助谷神。碎米浓作汁，饮如乳酪，与儿大豆许数令咽之，频与三豆许，
三、七日可与哺，慎不得取。次与杂药红雪少少得也。（《千金》亦有此说。又云∶止日三与之，满七日，可与哺也。）
《千金》云∶儿生十日始哺如枣核，二十日倍之，五十日如弹丸，（《圣惠》云∶二十日。）百日如枣，若乳汁少，
不得从此法，当用意小增之。若二十日而哺者，令儿无疾。儿哺早者，儿不胜谷气，令生病，头面身体喜生疮，愈
而复发，令儿 弱难养。三十日后，虽哺勿多。若不嗜食，勿强与之。强与之不消，复生疾病。哺乳不进者，
腹中皆有痰癖也。当以四物紫丸微下之。（方见变蒸门。）节哺乳，数日便自愈。小儿微寒热，亦当尔利之，要当下
之，然后乃瘥。
《千金翼》∶凡小儿不能哺乳，当服紫丸下之。
《千金翼》∶小儿生满三十日，乃当哺之。若早哺之，儿不胜谷气，令儿多肉耗。
姚和众云∶小儿初生七日，助谷神以导达肠胃，研粟米煮粥饮，浓薄如乳，每日研与半粟谷。
《婴孺》论云∶婴儿二十日乃哺，令儿无病。儿早哺而多头面身体生疮，愈则复发，令儿 弱难养也。又孙
氏《翼》云∶生满三日，乃当哺。若不胜谷气，令儿病。若不嗜食，勿强与之。与之则不消，成病而乳不进，
令腹中有痰癖也。当以四物双丸微下之即乳。数日自愈。
《婴童宝鉴》云∶小儿五十日可哺，哺如枣核许。百日加之如弹丸，早晚二哺，其后莫抱于檐下，澡浴当风
解衣，哭未断而乳，胃冷而哺。又不可在神佛前及驴马之畔，各房异户之亲，诸色物器并不可触犯，切宜慎之。
犯之即害子性命，乃为惊痫。经云∶未三岁勿食鸡肉，子腹中生虫。
钱乙云∶小儿多因爱惜过当，往三两岁犹未与饮食，致脾胃虚弱，平生多病。自半年以后，宜煎陈米稀粥，
取粥面时时与之。十月以后，渐与稠粥烂饭，以助中气，自然易养少病。惟忌生冷、油腻、甜物等。
*Ge Shi Zhou Hou* records: After three days of birth, a newborn should begin to assist the "Gu Shen" (a concept referring to introducing grain-based diet to aid spleen and stomach transformation). Crushed rice is boiled into a thick liquid with a consistency like yogurt or cream. It is given to the infant to swallow, in amounts equivalent to three soybeans per dose, administered frequently. By the third or seventh day, complementary feeding may begin; caution must be exercised to avoid premature or excessive feeding. Subsequently, a small amount of mixed medicine "Hong Xue" (Red Snow) may be given. (*Qian Jin Fang* also mentions this. It further states: Feed only three times a day; after seven full days, formal feeding may commence.)
*Qian Jin Fang* states: At ten days old, an infant should begin eating food the size of a jujube pit; at twenty days, double that amount; at fifty days, the size of a bullet; and at one hundred days, the size of a jujube. If breast milk is insufficient, one cannot rely solely on this method; one should carefully and appropriately increase the feeding volume slightly. Feeding at twenty days allows the infant to remain disease-free. Premature feeding causes the infant's body to be unable to handle the "Grain Qi" (digestive energy from grains), leading to illness. The head, face, and body are prone to sores, which recur after healing, resulting in a weak infant who is difficult to nurture. After thirty days, even if feeding, do not overfeed. If the infant refuses food, do not force it. Forced feeding leads to indigestion and subsequent illness. Failure to take breast milk indicates "Tan Pi" (phlegm-fluid accumulation forming masses) in the abdomen. One should use *Si Wu Zi Wan* (Four-Ingredient Purple Pill) for mild purgation. (Formula see section on Bian Zheng/Transformation Fever). Regulate breastfeeding; self-healing will occur within a few days. For infants with slight chills and fever, treatment should follow this approach; purgation is necessary before recovery can be achieved.
*Qian Jin Yi Fang* states: For any infant unable to take breast milk, *Zi Wan* (Purple Pill) should be administered for purgation.
*Qian Jin Yi Fang* further states: An infant should only begin solid feeding after thirty full days of life. Premature feeding causes the infant to be unable to handle Grain Qi, leading to emaciation and muscle wasting.
Yao Hezhong says: Seven days after birth, assist Gu Shen to guide and unblock the intestines and stomach. Grind millet and cook into porridge for drinking, with a consistency thin like milk. Grind half a millet grain's worth daily to feed the infant.
*Ling Ru Lun* states: Infants should begin feeding at twenty days to prevent disease. Premature feeding leads to sores on the head, face, and body, which recur after healing, causing weakness and difficulty in nurturing. Additionally, Sun's *Yi* states: Feeding should only begin after three full days of life. Inability to handle Grain Qi causes illness. Refusal to eat should not be forced. Forced feeding results in indigestion, illness, failure to take milk, and abdominal Tan Pi. *Si Wu Shuang Wan* (Four-Ingredient Double Pill) should be used for mild purgation to restore lactation. Self-healing occurs within a few days.
*Tong Bao Bao Jian* states: Infants may begin feeding at fifty days, with portions the size of a jujube pit. At one hundred days, increase to the size of a bullet. Feed twice daily, morning and evening. Thereafter, do not bathe the child under eaves where wind blows while undressed. Do not breastfeed while the infant is still crying, as this causes cold stomach and improper feeding. Avoid locations near deities, Buddhas, donkeys, or horses. Relatives from different households or rooms, and various objects, must not be offended; strict caution is required. Offending these taboos harms the child's life, leading to Jing Xian (startle epilepsy). Classics state: Do not eat chicken meat before age three, as it causes worms to grow in the child's abdomen.
Qian Yi states: Children often suffer from excessive parental affection, resulting in no solid food being given until two or three years old. This leads to spleen and stomach deficiency and lifelong illness. From six months onward, boil aged rice into thin porridge and feed the surface layer (rice oil) frequently. After ten months, gradually introduce thick porridge and soft rice to support Middle Qi (Spleen/Stomach energy). Naturally, the child becomes easier to raise and falls ill less. Only raw/cold foods, greasy foods, and sweet substances are taboo.
