小儿惊啼者，是于眠睡里忽然而惊觉也。由风热邪气乘于心，则心脏生热，精神不定，
故卧不安，则惊而啼也。
小儿夜啼者，脏冷故也。夜阴气盛，与冷相搏则冷动，冷动与脏气相并，或烦或痛，故
令小儿夜啼也。然亦有犯触禁忌，亦令儿夜啼，则可法术断之。
小儿在胎时，其母将养伤于风冷，邪气入胞，伤儿脏腑。故儿生之后，邪犹在儿腹内，
邪动与正气相搏则腹痛，故儿 张蹙气而啼。
小儿在胎时，其母将养取冷过度，冷气入胞，伤儿肠胃。故儿生之后，冷气犹在肠胃之
间。其状，儿肠胃冷，不能消乳哺，或腹胀，或时谷痢，令儿颜色素 、时啼者，是
胎寒故也。
小儿腹痛，多由冷热不调，冷热之气，与脏腑相击，故痛也。其热而痛者，则面赤，或
壮热，四肢烦，手足心热是也；冷而痛者，面色或青或白，甚者乃至面黑，唇口、爪皆青是
小儿心腹痛者，肠胃宿挟冷，又暴为寒气所加，前后冷气重沓，与脏气相搏，随气上下
，冲击心腹之间，故令心腹痛也。
解颅者，其状小儿年大，囟应合而不合，头缝开解是也。由肾气不成故也。肾主骨髓，
而脑为髓海；肾气不成，则髓脑不足，不能结成，故头颅开解也。
小儿囟填，由乳哺不时，饥饱不节，或热或寒，乘于脾胃，致腑脏不调，其气上冲所为
也。其状，囟张如物填其上，汗出，毛发黄而短者是也。若寒气上冲，即牢硬；热气上
冲，即柔软。
又，小儿胁下有积，又气满而体热，热气乘于脏，脏气上冲于脑囟，亦致囟填。又，咳
且啼，而气乘脏上冲，亦病之。啼甚久，其气未定，因而乳之，亦令囟填。所以然者，方啼
之时，阴阳气逆上冲故也。
Infantile startled crying refers to the sudden awakening from sleep due to fright. This occurs when wind-heat pathogenic factors invade the Heart, generating heat in the Heart organ and causing mental instability. Consequently, sleep is restless, leading to startled crying.
Infantile nocturnal crying is caused by coldness in the viscera. Nighttime is characterized by abundant Yin qi; when this interacts with internal cold, the cold stirs and combines with the Qi of the viscera, causing irritability or pain, thus resulting in nocturnal crying. However, some cases are caused by violating taboos, which can be stopped through magical methods.
During gestation, if the mother's care was compromised by wind-cold, pathogenic factors entered the uterus and damaged the fetus's viscera. After birth, these pathogens remain in the infant's abdomen. When the pathogens stir and contend with the healthy Qi, abdominal pain ensues, causing the infant to cry while stretching limbs and frowning.
If the mother excessively consumed cold substances during gestation, cold qi entered the uterus and damaged the fetus's intestines and stomach. After birth, the cold qi remains between the intestines and stomach. The presentation includes: cold intestines and stomach unable to digest milk and food, abdominal distension, or intermittent grain dysentery, leading to a pale complexion and frequent crying. This is termed fetal cold.
Infantile abdominal pain is mostly due to imbalance of cold and heat. The conflicting cold and heat Qi strike the viscera, causing pain. In heat-type pain, the face is red, possibly with high fever, restlessness in the four limbs, and heat in the palms and soles. In cold-type pain, the face may be cyanotic or pale; in severe cases, the face turns black, and the lips, mouth corners, and nails become cyanotic.
Infantile epigastric and abdominal pain occurs when chronic cold lingers in the intestines and stomach, compounded by an acute attack of cold Qi. The overlapping cold Qi contends with the visceral Qi, moving up and down with the Qi mechanism, striking the heart and abdomen, thus causing pain.
Craniolysis (splitting of the skull sutures) presents as delayed closure of fontanelles and splitting of cranial sutures in older infants. This is due to insufficient Kidney Qi. The Kidneys govern bone marrow, and the brain is the sea of marrow; insufficient Kidney Qi leads to inadequate marrow and brain development, failing to fuse properly, resulting in split cranial sutures.
Infantile bulging fontanelle is caused by irregular feeding, unregulated hunger and satiety, or exposure to heat or cold invading the Spleen and Stomach. This disrupts visceral harmony, causing Qi to rush upward. The presentation includes a bulging fontanelle filled with material, sweating, and yellow, short hair. If cold Qi rushes upward, the fontanelle feels hard; if heat Qi rushes upward, it feels soft. Additionally, subcostal accumulation with abdominal fullness and fever allows heat Qi to invade the viscera and rush upward to the brain and fontanelle, also causing bulging fontanelle. Coughing and prolonged crying cause Qi to invade the viscera and rush upward, also causing this condition. Feeding immediately after prolonged crying, when Qi has not yet settled, also causes bulging fontanelle. This is because during crying, Yin and Yang Qi rebel and rush upward.
