Then every day will defecate, sometimes newborns may not defecate a day, this phenomenon, parents should not be anxious, this is basically a normal phenomenon. The newborn baby is either breast-fed or breast-fed, that is to say, fluid, so 2 to 3 days stool once, or 3 to 5 times a day stool, this is normal, this and the child’s intestinal absorption function is related. It is often seen that some newborns, soon after birth, defecate a large amount of fetal stool, and then for a day or two the child will appear no stool phenomenon, and then the child will discharge yellow normal stool, these are normal, parents do not need to worry. The reason for this phenomenon in newborns is that the child’s defecation mechanism is not yet mature, and often requires more stool to stimulate the nerves of the rectal wall, feel the pressure of expansion, causing the defecation reflex, so a day without stool does not necessarily mean that it is constipation, as long as the nature of the newborn’s stool is normal, this means that there is no problem. Generally speaking, newborns will defecate every day, occasionally a day without poop, the main evaluation of newborns have no problems is to see whether the general condition of the child, whether there is no bloating, there is no crying, if not, the child can eat, can sleep, can play, this is normal, parents do not need to worry, no special treatment.
