Two-month-old babies have immature organ functions and low immunity, so once a high fever does not subside, the condition can easily worsen, forming risks such as pneumonia, sepsis, and even intracranial infections. Therefore, while taking active measures to reduce the fever, you should take your baby to the pediatric emergency room as soon as possible to assess the infection status, find the cause, and treat it for the cause. When the fever is high, the baby should be given fever-reducing medication in time, such as ibuprofen drops, etc. After taking the fever-reducing medication, the child can be properly hydrated. Because the high fever does not subside, physical cooling methods can be used at the same time, such as putting cooling patches on the forehead, neck and armpits to assist in reducing the fever, or using a warm water bath, or giving the baby a warm bath, which can also assist in reducing the fever. The baby’s diet should be managed with small and frequent meals, and he should wear relatively loose cotton clothes to facilitate sweating, heat dissipation and fever reduction.
