A child of more than 2 months does not poop for a few days, it depends mainly on what the child’s feeding method is, for example, breastfeeding can be a few days without pooping, and the child is not crying, nor is he bloated, nor does he have other symptoms, it may be a saved belly. Generally speaking, if the child does not poop for 5 days, it is necessary to find out the cause, give him belly rub, give the child water, including some passive exercises, which can relieve the symptoms of not pooping. If you are eating formula milk and your stools are not very regular and dry, you should consider whether there is any indigestion or constipation, that is to say, the first formula feeding depends on the ratio of formula milk, the second formula feeding should give the baby water, and the third is to rule out any gastrointestinal malformations, such as the manifestation of megacolon, the progressive elongation of the interval between stools, accompanied by abdominal distension, and the abdominal ultrasound can be used for preliminary screening. If the child does not pull for 3-5 days, he can be observed. If he does not pull for more than 5 days, he may need to be treated with soap bars or paediatric open cork, and if the stool is dry, he should drink water and do passive exercises to promote gastrointestinal motility and digestion. If it is thin, it may be related to the imperfect development of gastrointestinal function.
