Breastfeeding your child when you have a fever of 38.5℃ is basically not a problem. As long as the fever is 38.5℃ caused by common cold, cough or abdominal pain or diarrhea, breastfeeding basically does not affect the child too much. At this time, although there are viruses and bacteria in the mother’s body that can cause infection in the child, breast milk contains a large number of antibodies, which can help the baby to strengthen its resistance and resist foreign viruses or bacteria, instead of getting sick, breastfeeding has no effect. However, if the mother has a fever caused by viral flu, she needs to stop breastfeeding her child, which may aggravate the child’s infection. It is best to isolate the child because the influenza virus is particularly pathogenic and may cause infection in the child. In addition, you can give your child more water or juice, which can effectively prevent the occurrence of flu or cold, which is very beneficial to prevent the disease.
