what is a high temperature for a baby

According to the search results, a high temperature for a baby is generally considered to be a temperature of 38°C (100.4°F) or above. However, for infants younger than 3 months old, any fever, which is defined as a rectal temperature of 100.4°F (38°C) or higher, should be reported to a doctor or taken to the emergency department right away. If a baby is between 3 and 6 months old and has a temperature up to 102°F (38.9°C) and seems sick, or has a temperature higher than 102°F (38.9°C), parents should contact their healthcare provider. It is important to note that a fever itself is not harmful and can even be helpful as it can help the immune system fight infections. However, if a baby has a fever along with other symptoms such as a rash or is unusually irritable, parents should contact their healthcare provider.
