小儿吐泻，有身温者，有身热者，有身凉者，有吐泻成惊风者，有夏秋伤暑吐泻者，有初生三日内吐泻者。仲阳云∶
小儿初生三日内，吐泻壮热不思乳食，大便青白，乳食不消，或白色，是伤乳，当下之，后和胃，下用白饼子，和胃用
益黄散主之。三日以后至十日，吐泻，身温凉，不思乳食，大便青白色，乳食不消，此上实下虚也，用益黄散加减治之。
又伤风吐泻身温，乍凉乍热，气粗，大便黄白色，呕吐乳食不消，时时咳嗽，更有五脏兼见症，当服入脏君臣药，先大
青膏，后益黄散主之。又吐泻身热多睡能食乳，饮水不止，吐痰，大便黄水，皆为胃虚热渴吐泻也，当生胃中津液以止
其渴，止后用发散药，止渴多服白术散，发散大青膏、钩藤饮主之。又吐泻身凉吐沫，泻青白色，闷乱不渴，哽气长出
气，睡露睛，此伤风荏苒轻怯，因成吐泻，当补脾后发散，补脾益黄散，发散大青膏、钩藤饮。夏至后吐泻身壮热，热
症也，或因伤热，乳食呕吐不消，泻深黄色，玉露散主之，五苓散亦佳，香薷散、车前子散、可选而用之。若面色青黄，

Pediatric vomiting and diarrhea may present with a warm body, a hot body, or a cold body; some cases develop into convulsions (Jing Feng) due to vomiting and diarrhea; some occur in summer and autumn due to heatstroke (Shang Shu); and some occur within the first three days after birth.
Qian Yi (courtesy name Zhongyang) stated:
Within the first three days after birth, if an infant presents with vomiting, diarrhea, high fever, anorexia, greenish-white stools, indigestion of milk and food, or white vomitus, this is caused by milk injury. It should be treated with purgation, followed by harmonizing the stomach. For purgation, use Baibing Zi (White Pill), and for harmonizing the stomach, use Yihuang San (Golden Yellow Powder).
From the third day to the tenth day after birth, if vomiting and diarrhea occur with a normal or cool body temperature, anorexia, greenish-white stools, and indigestion of milk and food, this indicates excess in the upper jiao and deficiency in the lower jiao. It should be treated with modified Yihuang San (Golden Yellow Powder).
If vomiting and diarrhea are caused by wind-cold invasion, presenting with a warm body, alternating chills and fever, coarse breathing, yellowish-white stools, vomiting of undigested milk/food, frequent coughing, and concurrent symptoms of the five zang organs, one should administer herbs targeting the zang organs. First use Daqing Gao (Green Paste), followed by Yihuang San (Golden Yellow Powder).
Furthermore, if vomiting and diarrhea are accompanied by fever, lethargy yet ability to suckle, excessive thirst, vomiting of phlegm, and yellow watery stools, these are signs of stomach deficiency-heat leading to thirst and vomiting/diarrhea. One should generate fluids in the stomach to quench thirst, and subsequently use dispersing herbs. For quenching thirst, take Baizhu San (Atractylodes Macrocephala Powder); for dispersing, use Daqing Gao (Green Paste) and Gouteng Yin (Uncaria Decoction).
If vomiting and diarrhea present with a cold body, salivation, greenish-white stools, restlessness without thirst, belching with long sighs, and sleeping with eyes partially open, this is mild weakness resulting from prolonged wind-cold invasion causing vomiting and diarrhea. One should tonify the spleen first, then disperse pathogens. Use Yihuang San (Golden Yellow Powder) to tonify the spleen, and Daqing Gao (Green Paste) with Gouteng Yin (Uncaria Decoction) to disperse.
Vomiting and diarrhea occurring after the Summer Solstice with high fever belong to heat syndromes, possibly due to heat injury. If milk and food are vomited undigested and stools are deep yellow, use Yulu San (Jade Dew Powder). Wuling San (Five-Ling Powder) is also excellent; Xiangru San (Elsholtzia Powder) and Cheqianzi San (Plantago Seed Powder) can be selected as appropriate.
If the complexion is greenish-yellow, it indicates wind-heat in the spleen. Straightened hair, fear of people, and eyes failing to close suggest toxic fluid in the heart, compounded by stomach rebellion and wind convulsions. Dingming Dan (Life-Stabilizing Pill) can be administered.

After lying down for a short while, she may then breastfeed the infant.
