It is very common for children to come down with different illnesses that could lead to a fever since they are typically near many other children daily, but it can be tricky to decide when a fever is something to be of concern. It is recommended that you seek medical attention for your child that has a fever if they are under 3 months of age if they are struggling to breathe properly if they continue to be lethargic and not themselves even after medication is provided if they are very dehydrated if they are experiencing other sores or aches anywhere on their body, and if they have a rash that appears like a bruise on their body. Most fevers during infection are normal and while they should be closely monitored, are rarely of significant concern.
