《产经》云∶凡小儿生三日后，应开腹助谷神。可研米作浓饮如乳酪状。抄如大豆粒大，
与儿咽之，咽三豆许止，日三与之，七日可与哺。十日始哺，如来核许。二十日倍之。五十
日如弹丸许，百日如枣许。若乳汁少者，不从此法，当用意少增之。
今按∶《本草》云∶以如梧子十六枚准。（弹丸一枚。）
一云∶二十日后可乃始哺，令儿无疾也。若早与哺者，儿头、面、体喜生疮。亦令儿虚
羸难长。若儿大小随宜哺增减之良。
凡小儿不嗜哺者，勿强与，强与哺不消，便致疾病也。
又云∶初哺小儿良日∶
五寅、五辰、五丑、五酉，皆大吉。
又云∶男以甲乙，女以壬癸，亦吉。
又云∶以成、收、开、定、满日，义日，保日，皆吉，哺儿，儿终身无病，大吉。（义
日∶壬申、癸酉；保日∶甲午、乙巳。）
又云∶哺小儿忌日∶
五戌、五巳、五亥、丁日，大凶。
又∶戊戌、戊辰、执、闭日，皆大凶。
《产经》云∶小儿初生时洗浴，以牛脂小置汤中，令儿至老无疾。一云∶香脂大如指，
投汤中浴之，大佳。香脂是半脂也。
又云∶小儿初生，以虎头骨渍汤中洗浴之，令儿不病。
又云∶小儿初生以洗浴，以金银珍宝珠玉等投汤中，儿必为贵尊，大吉。
又云∶小儿初浴汤法∶桃根、李根、梅根三物，以水煮取汁洗浴儿，却诸不祥，令儿身
无疮，大吉。（今按∶《千金方》云∶以猪胆一枚，投汤中浴儿，终身不患疮疥。）
又云∶凡小儿浴数，数者，令儿背冷，发痫。若久不洛者，令儿毛落，亦复令啼呼之。
间一二日浴之良。
又云∶浴小儿良日∶
丑、寅、卯、申、酉。
又∶甲寅、乙未、丙午、丁酉、癸酉，癸未、甲辰，皆吉。令儿终身无疾病，长寿，大
吉。
又云∶浴小儿忌日∶
庚戌、壬子、甲乙、庚辛、壬癸、辰巳、午未、亥，大凶。
又∶男忌戌日，女忌丁日，大凶。

The *Chan Jing* (Classic of Childbirth) states: For any infant three days after birth, one should begin auxiliary feeding to assist the "Gu Shen" (Grain Spirit, referring to postnatal Spleen-Stomach Qi). Rice can be ground into a thick drink resembling yogurt. Take an amount the size of a soybean, and allow the infant to swallow it. Stop after swallowing approximately three bean-sized portions. Administer this three times a day. After seven days, solid food (complementary feeding) may be introduced. At ten days old, introduce food in amounts the size of a walnut kernel. At twenty days old, double the amount. At fifty days old, the amount should be like a small pellet; at one hundred days old, like a date. If breast milk is insufficient, do not follow this method strictly; instead, use discretion to increase the amount slightly.
Current examination: The *Ben Cao* (Materia Medica) records: Use sixteen seeds of Sophora japonica (Wu Zi) as the standard measure. (One pellet is equivalent to one Sophora seed.)
Another opinion states: Complementary feeding should only begin after twenty days, so that the infant remains free from disease. If feeding is started too early, the infant's head, face, and body are prone to developing sores. It also causes the infant to become emaciated and difficult to grow. It is beneficial to adjust the amount of complementary feeding appropriately according to the infant's size.
If an infant does not desire complementary food, do not force it. Forcing food leads to indigestion, which subsequently causes illness.
It is further stated: Auspicious days for first introducing complementary food:
The Wu Yin days, Wu Chen days, Wu Chou days, and Wu You days are all highly auspicious.
It is also stated: For males, Jia and Yi days are used; for females, Ren and Gui days are used; these are also auspicious.
It is also stated: Cheng days, Shou days, Kai days, Ding days, and Man days, as well as Yi days and Bao days, are all auspicious. Feeding complementary food on these days ensures the infant remains disease-free throughout life, which is highly auspicious. (Yi days refer to Ren Shen and Gui You days; Bao days refer to Jia Wu and Yi Si days.)
It is also stated: Inauspicious days for feeding complementary food:
The Wu Xu days, Wu Si days, Wu Hai days, and Ding days are highly inauspicious.
It is also stated: Wu Xu days, Wu Chen days, Zhi days, and Bi days are all highly inauspicious.
The *Chan Jing* states: When bathing a newborn infant, adding a small amount of beef tallow (Niu Zhi) to the bathwater allows the infant to remain disease-free until old age. Another opinion suggests adding aromatic balm (Xiang Zhi) the size of a finger to the bathwater, which is very effective. Xiang Zhi refers to half-fat (Ban Zhi).
It is also stated: When bathing a newborn, soaking tiger skull bone (Hu Tou Gu) in the bathwater prevents illness.
It is also stated: When bathing a newborn, adding gold, silver, precious stones, pearls, and jade to the bathwater ensures the infant will become noble and respected, which is highly auspicious.
It is also stated: The method for bathing a newborn: Boil peach root (Tao Gen), plum root (Li Gen), and apricot root (Mei Gen) to extract the juice, and use it to bathe the infant. This dispels all misfortune and ensures the infant's body remains free from sores, which is highly auspicious. (Current examination: The *Qian Jin Fang* states: Adding one pig gallbladder (Zhu Dan) to the bathwater ensures the infant will never suffer from sores or scabies throughout life.)
It is also stated: Regarding the frequency of bathing infants: Bathing too frequently causes coldness in the back and may induce epilepsy (Xian). Bathing too infrequently causes hair loss and excessive crying. It is best to bathe the infant every one or two days.
It is also stated: Auspicious days for bathing infants:
Chou days, Yin days, Mao days, Shen days, and You days.
It is also stated: Jia Yin days, Yi Wei days, Bing Wu days, Ding You days, Gui You days, Gui Wei days, and Jia Chen days are all auspicious. They ensure the infant remains disease-free throughout life and enjoys longevity, which is highly auspicious.
It is also stated: Inauspicious days for bathing infants:
Geng Xu days, Ren Zi days, Jia and Yi days, Geng and Xin days, Ren and Gui days, Chen and Si days, Wu and Wei days, and Hai days are highly inauspicious.
It is also stated: Males should avoid Xu days, and females should avoid Ding days; these are highly inauspicious.
It is also stated: Pingdan (early morning), Rizhong (noon), Huanghun (dusk), and Ye Ban (midnight) are highly inauspicious times for bathing.
