夜啼者，有阴阳二证。阴者脏冷也。夜则阴盛，与冷相搏，脏气交击，故作痛而啼。阳
者脏热，夜则阳衰，
与脏热交击，亦作痛而啼也。

夜啼，分为阴证和阳证两种。阴证是脏腑寒冷所致。夜间阴气旺盛，与体内的寒气相互搏结，脏腑之气相互冲击，因此产生疼痛而啼哭。阳证是脏腑有热，夜间阳气衰弱，（虚阳）与脏腑之热相互冲击，同样会产生疼痛而啼哭。

《幼幼新书》记载：钟声洪亮宏大，涧水流淌长远。胎儿处于胞胎之中，禀受的气血充足，水火既济，心肾不亏，所以发出的声音清脆响亮洪亮，这是根本深厚强壮、禀赋充实的自然道理。刚出生时的啼哭，如果声音发不出来，或者短促呃逆，上下之气不相顺承，这是由于胎气不足，根本不壮，何必用药呢？即使凭主观意图投药，最终也不是能健康长大的孩子，医生应当不可不仔细考察。
小儿客忤，是指外人带来的秽恶邪气冲犯婴儿。一旦中人，就称为客忤。即使是父母家人，如果是从远方来到，或者经过神庙、丧门方位，饮酒骑马突然到来，汗气、秽气靠近婴儿，一旦沾染上，都算是客忤。凡是婴儿中了客忤，面色变为五色变幻，症状像惊痫，但眼睛不上翻，或者口吐青白色泡沫，喘息腹痛，身体反侧抽搐，如同受惊一般。这是因为小儿心气虚弱，精神不足，容易受到客忤之气的侵犯，切不可当作惊风来治，应当补益心神，自然就不畏惧侵犯了。凡是中客忤引发抽搐，脉象弦急而数，面色改变，观察其口中悬雍垂左右有小水泡，立即用竹刺破溃它，或者用指甲掐破它，药用避邪正气散来安神，病自然会痊愈。
Night crying is divided into two syndromes: Yin and Yang. The Yin syndrome is due to coldness of the Zang organs. At night, Yin Qi (Yin energy) is abundant, clashing with the internal cold; the Qi of the Zang organs strikes each other, causing pain and crying. The Yang syndrome is due to heat in the Zang organs. At night, Yang Qi is weak; this deficiency interacts with the organ heat, also causing pain and crying.

The *Youyou Xinshu* (New Book for Infants and Children) states: "Bell sounds are loud and resonant; stream waters flow far and long." While in the womb, the fetus receives ample Qi, with Water and Fire mutually supporting, and Heart and Kidney unimpaired. Thus, the voice emitted is clear, loud, and resonant. This is because the root is deep and strong, and the innate constitution is full, which is the natural principle. If a newborn cries but produces no sound, or has short, hiccup-like sounds, indicating that upper and lower Qi do not support each other, this is due to insufficient fetal Qi and an unsteady root. Why use medicine? Even if one prescribes medicine based on speculation, such a child will likely not grow up healthy. Physicians must examine this carefully.
Pediatric Ke Wu (Guest Intrusion) refers to foul and evil pathogenic Qi brought by outsiders invading the infant. Once it affects the person, it is called Ke Wu. Even parents or family members can cause this if they come from afar, have visited temples or places associated with mourning, have been drinking or riding horses, or approach the infant with sweat or foul odors. Once infected, it constitutes Ke Wu. When a child suffers from Ke Wu, the face changes color through five hues, resembling Jing Xian (Startle Epilepsy), but the eyes do not roll upward. There may be vomiting of blue-white foam, panting, abdominal pain, and body twisting/trembling, similar to fright. This occurs because the child's Heart Qi is deficient and Spirit is lacking, making them susceptible to Ke Wu Qi. It must not be treated as Fright (Jing); instead, the Heart Spirit should be tonified, and fear/invasion will naturally subside. When Ke Wu triggers convulsions, the pulse is wiry, rapid, and tense, and the facial color changes. Observe the uvula area in the mouth; if there are small blisters on either side, puncture them immediately with a bamboo splinter or scratch them with fingernails. Prescribe Bixie Zhengqi San (Expel Evil and Rectify Qi Powder) to calm the Spirit, and the condition will resolve spontaneously.
