巢氏曰∶小儿在胎受母热毒，生下遍身面目俱壮热，大便秘，小便黄色，多啼不乳。
《千金》论云∶小儿生下，遍身面目皆黄如金色，身上壮热，大便不通，小便浊赤，
不思乳食，啼叫不止，此胎黄之候也。皆因母受热而传于胎也。有此证者，乳母服地黄汤。
胎黄胎疸证，母子俱宜服地黄汤及地黄饮子。小儿百日内及半周，不因病后身微黄者，
胃热也。若自生而身黄者，胎疸也。经云∶诸疸皆热，色深黄者是也，犀角散主之。若淡黄兼
白者，胃怯也，白术散主之。（方见泻门。）

小儿生后有脐风证者，多因断脐带后为风湿所伤而成也。风入脐者，令脐肿腹胀，口
撮多啼，不能乳饮，谓
之脐风。若入经络，多变为痫，当作痫证治之。
脐风致于四肢柔直，日夜多啼，不能吮乳，甚则发为风搐。若脐边青黑，撮口不开，
是为内搐，不治。爪甲黑者则死。
巢元方说：胎儿在母体内受到母亲热毒的影响，出生后全身及面目都出现高热，大便秘结，小便颜色发黄，经常啼哭且不愿吃奶。
《千金方》论述说：小儿出生后，全身及面目都呈现如金色般的黄色，身体高热，大便不通畅，小便浑浊赤红，不想吃奶，啼叫不止，这就是胎黄的证候。这都是因为母亲受热后传给胎儿所致。有此证候的，乳母应服用地黄汤。
胎黄和胎疸证候，母子双方都适宜服用地黄汤及地黄饮子。小儿在百日内及半周岁时，如果不是因病后导致身体微黄，则是胃热所致。如果是出生即身体发黄，则是胎疸。医经说：各种黄疸都属于热证，颜色深黄的就是此类，用犀角散主治。如果颜色淡黄兼带白色，则是胃气虚弱，用白术散主治。（方剂见泻门章节。）

小儿出生后患有脐风证候的，多是因为断脐带后受到风湿邪气侵袭而形成的。风邪侵入脐部，会导致脐部肿胀、腹部胀满，口唇收缩、经常啼哭，不能喝奶吃食，这称为脐风。如果风邪侵入经络，多会转变为痫病，应当作为痫证来治疗。
脐风导致四肢僵硬挺直，日夜啼哭不止，不能吮吸乳汁，严重时发展为风搐。如果脐边颜色青黑，口唇紧闭不开，这是内搐，属于不治之症。指甲发黑的则预后不良，主死。
Chao Yuanfang stated: If a fetus is affected by maternal heat-toxin during gestation, after birth the entire body and face will exhibit high fever, constipation, yellow urine, frequent crying, and refusal to nurse.
The *Qianjin Fang* (Essential Prescriptions Worth a Thousand Gold) discusses: After birth, if an infant's entire body and face appear golden-yellow, accompanied by high fever, constipation, turbid red urine, loss of appetite for milk, and incessant crying, this is the manifestation of fetal jaundice (Taihuang). This is caused by maternal heat transmitted to the fetus. For those with these symptoms, the nursing mother should administer Dihuang Tang (Rehmannia Decoction).
For fetal jaundice (Taihuang) and fetal icterus (Taidan), both mother and child are suitable for taking Dihuang Tang (Rehmannia Decoction) and Dihuang Yinzi (Rehmannia Drink). If an infant under one hundred days old or half a year old has slight yellowing not due to post-illness recovery, it is due to stomach heat. If the yellowing is present from birth, it is fetal icterus (Taidan). The classics state: All types of icterus are heat-related; those with deep yellow color fall into this category, primarily treated with Xijiao San (Rhinoceros Horn Powder). If the color is pale yellow mixed with white, it indicates weak stomach qi, primarily treated with Baizhu San (Atractylodes Macrocephala Powder). (See formula in the Purging section.)

Infants who develop umbilical convulsion (Qifeng) after birth are mostly injured by wind-dampness after the umbilical cord is cut. When wind enters the umbilicus, it causes umbilical swelling and abdominal distension, mouth puckering, frequent crying, and inability to suckle, known as umbilical convulsion (Qifeng). If the pathogen enters the meridians, it often transforms into epilepsy (Xianbing) and should be treated as such.
Umbilical convulsion causing rigid limbs, incessant crying day and night, inability to suckle, and potentially developing into wind-tremors (Fengchu). If the area around the umbilicus turns cyan-black and the mouth cannot open, this is internal tremor (Neichu), which is incurable. Black fingernails indicate death.
