凡乳母气血为乳汁也。五情善恶，悉气血所生，宜戒喜怒，一切禁忌。不用狐臭瘿
嗽病者，及身体疥癣头疮，发少唇紧，音哑耳聋， 鼻痫病等，方可乳儿。夏天盛热时
母浴后，或儿啼，不可与奶，使儿胃有热毒，秋成赤白痢。浴后可令定息良久乳之，可
也。聂氏曰∶盛啼不可食乳，恐气逆不顺，聚而为 ，亦能成疾。千金论曰∶凡乳儿不
饱，饱则溢而成呕吐。若乳来多猛，取出捏后再乳。切须乳时合先令捏去宿热乳，然后
如乳母欲卧寐，当以臂枕之，令乳与儿头平。母欲睡着时，即夺其乳，恐其不知饱足
呕吐。父母交合之间，儿卧于侧，或惊起，不可乳儿。盖气乱未定，必能杀儿也。（
云∶醉淫喘乳，能杀小儿。圣济经论∶乳者夏不欲热，热则致吐逆。冬不欲寒，寒则
母不欲怒，怒则令上气癫狂，母不欲醉，醉则令身热腹满。母方吐下而乳，则致虚
积热而乳，则变黄不能食。新房而乳，则瘦悴交胫不能行。）
钱乙云∶儿多因爱惜过当，两三岁犹未饮食，致脾胃虚弱，平生多病。半年后宜煎
稀粥，时时与之，十月后渐与稠粥烂饭，以助中气，自然易养少病。惟忌生冷油腻甜物
（宝鉴云∶儿五十日可哺如枣核，百日弹丸，早晚二哺。三岁未满，勿食鸡肉及子，恐

乳汁是由乳母的气血化生而成的。人的七情（喜、怒、忧、思、悲、恐、惊）的善恶表现，完全取决于气血的状态，因此乳母应当戒除喜怒等情绪波动，遵守一切禁忌。不应让患有狐臭、瘿病（甲状腺肿大）、咳嗽病的人，以及身体患有疥癣、头疮，头发稀少嘴唇紧绷，声音嘶哑耳聋，或患有鼻部癫痫等疾病的人哺乳婴儿，这样才可以哺乳。在盛夏炎热之时，母亲沐浴后，或者婴儿啼哭时，不可立即喂奶，否则会使婴儿胃中产生热毒，到了秋天就会形成赤白痢疾。沐浴后应让母亲平复气息良久后再哺乳，这是可以的。聂氏说：婴儿剧烈啼哭时不可进食乳汁，恐怕气机逆乱不顺，积聚而成疳积（小儿慢性营养障碍性疾病），也能导致疾病。《千金方》论述说：凡是哺乳婴儿，不能喂得太饱，太饱了就会溢出而导致呕吐。如果乳汁来得又多又急，应挤出一些再让婴儿吸吮。切须注意，哺乳前应先令母亲挤出一些陈旧的乳汁（宿热乳），然后再进行哺乳。如果乳母想要躺下睡觉，应当用胳膊垫着枕头，使乳房与婴儿头部保持水平。当乳母快要睡着时，应立即停止哺乳，恐怕婴儿不知道饱足而继续吃导致呕吐。父母行房事期间，婴儿睡在旁边，或者受惊坐起，不可给婴儿哺乳。因为此时气机混乱尚未安定，必定会伤害婴儿。（《云笈七签》说：醉酒行房后哺乳，能杀死小儿。《圣济总录》论述：哺乳方面，夏天不希望乳汁过热，过热会导致呕吐逆乱。冬天不希望过寒，过寒则……母亲不应当发怒，发怒会导致上气癫狂；母亲不应当醉酒，醉酒会导致身体发热腹部胀满。母亲刚经历吐泻就哺乳，会导致虚证；积聚热邪就哺乳，会变成黄疸且不能进食。刚经过新房事就哺乳，会导致消瘦憔悴、小腿交叉无法行走。）
钱乙说：婴儿大多因为家长爱惜过度，到了两三岁还没有正常饮食，导致脾胃虚弱，一生多病。半年后的婴儿适宜煎煮稀粥，时常给予食用，十个月后的婴儿逐渐给予稠粥和烂饭，以辅助中气（脾胃之气），自然容易抚养且少生病。只忌讳生冷、油腻、甜食。（《幼幼新书》引《宝鉴》说：婴儿五十天可以喂食如枣核大小的食物，一百天如弹丸大小，早晚各哺喂两次。三岁未满，不要食用鸡肉及蛋类，恐怕生虫。）
Breast milk is transformed from the Qi and Blood of the nursing mother. The moral or immoral states of the Seven Emotions (Joy, Anger, Worry, Thought, Sadness, Fear, Fright) are entirely generated by Qi and Blood; therefore, the mother should abstain from joy and anger, and observe all taboos. One shall not nurse an infant if the person has fox odor, goiter (enlargement of the thyroid gland), or coughing diseases, nor if they have body tinea and scabies, head sores, sparse hair, tight lips, hoarseness, deafness, or nasal epilepsy, etc., before it is safe to nurse. During the intense heat of summer, after the mother takes a bath, or when the infant is crying, one must not provide milk, as this will cause heat-toxin in the infant's stomach, leading to dysentery with red and white discharge in autumn. After bathing, one should allow the mother to calm her breathing for a long time before nursing, which is acceptable. Nie said: Do not feed breast milk while the infant is crying violently, for fear that Qi will reverse and become unsmooth, accumulating to form malnutrition syndrome (chronic nutritional disorder in children), which can also cause disease. The *Qianjin Fang* discusses: When nursing an infant, do not overfeed; overfeeding causes overflow and vomiting. If the milk flow is abundant and forceful, express some out first before letting the infant suckle. It is crucial that before nursing, the mother should first express and discard some old milk (retained hot milk). If the nursing mother wishes to lie down and sleep, she should use her arm as a pillow to keep the breast level with the infant's head. When the mother feels sleepy, immediately remove the breast, for fear the infant does not know satiety and continues to eat, causing vomiting. During sexual intercourse between parents, if the infant is lying nearby or starts up in fright, do not nurse the infant. Because the Qi is chaotic and unsettled, it will surely harm the infant. (*Yunji Qiqian* states: Nursing after drunken intercourse can kill the infant. *Shengji Zonglu* discusses: Regarding nursing, in summer, heat is undesirable; heat leads to vomiting and reversal. In winter, cold is undesirable; cold then... The mother should not be angry, for anger causes upward Qi and mania; the mother should not be drunk, for drunkenness causes body heat and abdominal fullness. Nursing after recent vomiting or purging leads to deficiency; nursing with accumulated heat transforms into jaundice and inability to eat. Nursing after recent coitus leads to emaciation, wasting, and inability to walk with crossed legs.)
Qian Yi stated: Infants often suffer from excessive care; if they are not eating solid foods at two or three years of age, it results in Spleen and Stomach weakness and frequent illness throughout life. For infants after six months, thin rice gruel should be decocted and given occasionally. After ten months, thicker gruel and soft rice should be gradually introduced to assist Middle Qi (Spleen and Stomach Qi), making them naturally easier to raise and less prone to illness. Only raw/cold, greasy, and sweet foods are taboo. (*Youyou Xinshu* citing *Baojian* states: At fifty days, food like a date pit can be offered; at one hundred days, like a small ball, twice morning and evening. Under three years old, chicken meat and eggs should not be eaten, for fear of generating parasites.)
