Most children with low fever and diarrhea are suffering from diseases caused by gastroenteritis. It is necessary to bring down the body temperature of the child, because the child is relatively small and the temperature is not high, you can use physical cooling first to restore the child’s body temperature to normal, and then use Mamma’s Aid, Similac or Montelukast to help the baby stop diarrhea. You must pay attention to hygiene and let your child wash his hands before meals to avoid bacterial infections that can cause low fever and diarrhea. If your child does not keep his abdomen warm at night, it can also lead to low fever and diarrhea due to a cold abdomen. If your child’s fever and diarrhea do not improve in a long time, you should go to the hospital for routine blood and stool tests and abdominal ultrasound to rule out other diseases. During the treatment period, it is important to eat more light food, which is easier to promote digestion of the stomach and intestines.
