Common Childhood Illnesses
Coughs, colds, ear infections, and fevers are part of childhood. Here's a calm overview of common illnesses and the signs that mean it's time to see a doctor.
Frequent illness is part of childhood
Most are mild and pass on their own
How your child behaves matters most
Know the warning signs to seek care
Children get sick — frequently, especially in the early years as their immune systems develop. Most common illnesses are mild and pass on their own, but knowing what's normal and what needs a doctor takes some of the worry out of it.
Everyday illnesses
Coughs, colds, sore throats, ear infections, tummy bugs, and fevers are all common in childhood. Most are caused by viruses, run their course in a few days to a week, and are managed with comfort, fluids, and rest. Not every illness needs medication.
Fevers
A fever is the body's natural response to infection and isn't dangerous in itself for most children. How your child is behaving often matters more than the exact number — a child who is drinking, alert at times, and settling is usually reassuring.
When to see a doctor
Seek care if your child is very young with a fever, is unusually drowsy or hard to wake, is breathing fast or with difficulty, isn't drinking or has far fewer wet diapers, has a rash that doesn't fade under pressure, or seems to be getting worse rather than better. Trust your instincts — if you're worried, get them seen.
This is general information, not medical advice. For serious symptoms — difficulty breathing, a non-fading rash, unresponsiveness — seek urgent care or call 911.
