小儿哕，由哺乳冷，冷气入胃，与胃气相逆，冷折胃气不通，则令哕也。
小儿吐血者，是有热气盛而血虚，热乘于血，血性得热则流散妄行，气逆即血随气上，
凡小儿初生，看产人见儿出，急以手料拭儿口，无令恶血得入儿口，则儿腹内调和，无
有疾病；若料拭不及时，则恶血秽露儿咽入腹，令心腹痞满短气，儿不能饮乳，谓之难乳。
又云∶儿在胎之时，母取冷过度，冷气入胞，令儿着冷，至儿生出，则喜腹痛，不肯饮
乳，此则胎寒，亦名难乳也。
小儿吐 者，由乳哺冷热不调故也。儿乳哺不调，则停积胸膈，因更饮乳哺，前后
相触，气不得宣流，故吐 出。诊其脉浮者，无苦也。
小儿百病者，由将养乖节，或犯寒温，乳哺失时，乍伤饥饱，致令血气不理，肠胃不调
，或欲发惊痫，或欲成伏热。小儿气血脆弱，病易动变，证候百端，故谓之百病也。若见其
微证，即便治之，使不成众病；治之若晚，其病则成。
凡诸病，至于困者，汗出如珠，着身不流者，死也。病如胸陷者，其口唇干，目上反，
口中气出冷，足与头相柱卧，不举手足，四肢垂，其卧正直如缚得，其掌中冷，至十日必死
小儿呃逆，是由于哺乳时乳汁过冷，冷气进入胃中，与胃气相互冲逆，寒气遏制了胃气的通畅运行，从而导致呃逆。
小儿吐血，是因为体内热气亢盛而血液亏虚，热邪侵袭血液，血液受热后性质变得流动散乱而妄行，气机上逆则血液随气上涌而出。
凡是新生儿刚出生时，接生的人看到婴儿娩出，应立即用手擦拭婴儿的口腔，不要让恶血进入婴儿口中，这样婴儿腹内就能调和，不会发生疾病；如果擦拭不及时，导致恶血和污秽的胎脂进入咽喉并吞入腹中，引起心腹部痞闷胀满、呼吸短促，婴儿不能吸吮乳汁，这称为“难乳”。又说：婴儿在母体胎儿时期，母亲过度贪凉，冷气侵入胞宫，使胎儿受寒，等到婴儿出生后，就喜欢腹痛，不肯吃奶，这属于“胎寒”，也称为“难乳”。
小儿呕吐，是由于哺乳喂养冷热不调所致。婴儿哺乳不当，导致乳汁停滞积聚在胸膈之间，如果再继续喂奶，新旧乳汁相互触碰，气机无法宣通流畅，因此发生呕吐。诊察其脉象浮的，说明没有大碍。
小儿百病，是由于调养失当，或者触犯寒温失调，哺乳时间不规律，时而饥饿时而过饱，导致气血运行紊乱，肠胃功能不调，或者想要发作惊痫，或者形成伏热。小儿气血脆弱，病情容易变动，证候种类繁多，所以称为“百病”。如果见到轻微的证候，就立即治疗，使其不发展成多种疾病；如果治疗太晚，病情就会加重。
各种疾病，到了危重阶段，出汗像珍珠一样，沾在身上不流动的，是死症。病症表现为胸部凹陷的，口唇干燥，眼睛向上翻，口中呼出冷气，双脚顶着头部仰卧，手脚不能抬起，四肢下垂，身体躺得笔直像被捆绑住一样，手掌冰冷，到第十天必定死亡。
小儿有气血尚未充实的，皮肤腠理就比较疏松。如果穿得太厚、睡得太暖，脏腑产生内热，蒸发腠理，津液外泄流失，所以导致头部……
盗汗，是指在睡眠中汗水自行流出。小儿阴阳之气稚嫩虚弱，腠理容易开泄，如果调养过于温热，因此在睡卧时阴阳之气相交，津液发泄，从而汗水自行流出。
Infantile hiccups are caused by cold milk during breastfeeding; the cold qi enters the stomach, conflicts with the stomach qi, and the cold restricts the smooth flow of stomach qi, resulting in hiccups.
Infantile hematemesis occurs when internal heat is excessive while blood is deficient. Heat invades the blood; since blood becomes fluid and scatters when heated, it flows recklessly. When qi rebels upward, blood follows qi to the upper body and is vomited out.
Whenever a newborn is delivered, the midwife should immediately wipe the infant's mouth upon seeing the baby emerge, preventing foul blood from entering the infant's mouth. This ensures harmony within the abdomen and prevents disease. If wiping is delayed, foul blood and impure lochia enter the pharynx and are swallowed into the abdomen, causing epigastric and abdominal fullness, shortness of breath, and an inability to suckle milk; this condition is called "Nanru" (Difficult Suckling). It is also said that if the mother excessively exposed herself to cold during pregnancy, cold qi entered the uterus, causing the fetus to become cold. After birth, the infant suffers from abdominal pain and refuses to suckle; this is known as "Taihan" (Fetal Cold), which is also termed "Nanru".
Infantile vomiting is caused by improper temperature regulation of breast milk or supplementary foods. Improper feeding leads to stagnation and accumulation in the chest and diaphragm. Subsequent feeding causes interaction between old and new milk, obstructing the free flow of qi, thus leading to vomiting. If the pulse is floating, there is no serious concern.
The myriad diseases of infants arise from improper care, exposure to extreme cold or heat, irregular feeding times, and alternating states of hunger and overeating. These factors disrupt the regulation of blood and qi and impair gastrointestinal function, potentially leading to convulsions and epilepsy or latent heat. Because infants have fragile blood and qi, their conditions change easily, presenting diverse symptoms; hence they are referred to as "Bai Bing" (Hundred Diseases). If mild symptoms are treated promptly, the development of multiple diseases can be prevented; if treatment is delayed, the disease will progress.
In all diseases, when the condition becomes critical, sweat resembling pearls that adheres to the body without flowing indicates death. Symptoms such as sunken chest, dry lips, eyes rolling upward, cold breath exhaled from the mouth, lying supine with feet touching the head, inability to move limbs, hanging limbs, rigid posture as if bound, and cold palms indicate death within ten days.
Infants whose blood and qi are not yet solid have loose skin and interstices (Cou Li). If dressed too warmly or bedded too hotly, internal heat generates in the viscera, evaporating through the interstices, causing fluids to leak and escape, thereby leading to sweating on the head...
Night sweats refer to spontaneous sweating during sleep. Infants have tender and weak yin and yang qi, making their interstices prone to opening. If cared for with excessive warmth, during sleep when yin and yang qi interact, fluids are released, resulting in spontaneous sweating.
