A baby with a temperature of 37.3 degrees is considered to have a low fever. First of all, the baby should be put to bed and rest, and the indoor environment should be kept quiet, moderate in temperature and well ventilated. If your child is sweating a lot, you should change clean clothes and wipe the baby’s body with warm water in time. You can lower the body temperature through physical cooling methods by taking warm water and wiping the baby’s palms, feet, back and other parts that are easy to dissipate heat. You should pay attention to give your baby more water or breastfeeding, which can promote sweating and urination, which can take away some of the heat and germs, and is good for fever control. If the body temperature continues to rise above 38.5°C, consider taking medication to reduce the fever.
