Infants who are overfed may experience digestive discomfort, bouts of crying, changes in stool shape, loss of appetite, and excessive obesity. Overfeeding can cause nausea, vomiting, bloating and other indigestion symptoms in infants, which need to reduce the amount of food, along with medication to promote digestion and absorption, such as Bacillus subtilis bacillus granules and other probiotics. Bloating due to overfeeding can trigger paroxysms of pain, induce crying, and in severe cases can lead to gastrointestinal reactions such as vomiting and diarrhea. Overfeeding can lead to weakened digestion of food metabolism, which may result in foamy stools thin stools or yellow-green stools. And it will affect the time of the second feeding, which may cause the infant to be reluctant to eat. The baby may also gain weight beyond the normal standard within a short period of time. It is recommended to consult the pediatrician or nutritionist as soon as possible, and feed the baby reasonably under the doctor’s guidance, so as not to affect the normal growth and development of the baby.
