Irritable Child

It is normal for babies to act fussy when they are hungry or tired, or have a messy diaper. If your baby is still fussy after being fed, taking a nap, or getting a clean diaper, call your pediatrician for more advice. Fussiness in small babies can be a sign of illness.

If your baby has a fever (rectal temperature reading of 100.4 F/38 C or higher), call your pediatrician immediately! Fever in a young baby can be a sign of serious illness.
