Newborns are not fully developed in all aspects of their physiological functions and are very weak. If the child catches a cold, abdominal pain, diarrhea, belching, vomiting and other symptoms will occur. Pay special attention to keep the abdomen warm, give the child timely diarrhea, take Mamie’s or Similac. Also, give your child warm food and be careful not to drink cold water. Breast-fed children are okay, especially formula-fed children, the water temperature can be slightly hotter, but not more than 40 degrees Celsius.
