How does darling often have a fever to return a responsibility after weaning

The baby often has a fever after weaning, which needs to be considered due to changes in diet, resulting in a decline in the baby's body immunity; in addition, it may also be caused by an infection in the upper respiratory tract. Parents need to use antipyretic stickers to cool the baby when the baby has a low fever. If the baby has a high fever, they need to use antipyretic drugs to treat the baby.
