Childhood Illnesses Parents Commonly Ask About

Published November 2026 · 6 min read

A mother sits on her son's bed and offers him a glass of juice while he rests under a blanket.

It is 2 a.m., your child is hot to the touch, and every worry you have ever had arrives at once. Nearly every parent has been there. Children get sick often, especially in the first years of daycare and school, and most illnesses are mild and pass on their own. Knowing what is typical, what helps, and what deserves a call can turn a frightening night into a manageable one.

Colds and coughs

Young children can catch six to ten colds a year. Colds are caused by viruses, so antibiotics do not help. Symptoms such as runny nose, sneezing, mild sore throat and cough usually peak around days three to five and fade within ten days, though a cough can linger a bit longer. Over-the-counter cough and cold medicines are generally not recommended for young children, because the risks outweigh the small benefit. Honey can soothe a cough in children older than one year, but should never be given to infants.

Fever: what the number really means

Fever is a sign that the body is fighting an infection; it is not an illness itself. How your child acts often matters more than the exact number. A child with a fever who drinks, plays between doses of medicine, and is alert is usually reassuring. Call right away for any fever in a baby under three months, for a fever lasting more than a few days, or if your child seems unusually drowsy, is hard to wake, has a stiff neck, or has trouble breathing.

Ear infections and sore throats

Ear infections often follow a cold and are most common between six months and three years of age. Signs include ear pulling, fussiness, poor sleep and fever. Many mild cases improve without antibiotics, and clinicians often use a watchful approach in selected children. Sore throats are usually viral, but strep throat is a bacterial cause that requires a test and treatment. Sudden throat pain with fever, swollen glands and no cough is a good reason to be seen. A strep test and a look inside the ears both need an in-person visit.

Stomach bugs and dehydration

Vomiting and diarrhea are usually caused by viruses and often resolve in a few days. The main risk is dehydration. Watch for fewer wet diapers or trips to the bathroom, no tears when crying, a dry mouth, sunken eyes, or unusual sleepiness. Oral rehydration solutions are designed for this situation. Offer small, frequent amounts rather than large gulps. Blood in the stool, severe belly pain, green vomit, or an inability to keep any fluids down means it is time to call.

Rashes and skin concerns

Rashes have many causes, from eczema and heat to viral illnesses such as hand, foot and mouth disease. Most are harmless, but a rash that comes with high fever, spreads quickly, looks like bruising that does not fade when pressed, or appears with swelling of the lips or face needs prompt attention.

Comfort care you can do at home

  • Offer fluids often, in small sips if your child is nauseated.
  • Let your child rest; appetite usually returns on its own.
  • Use a cool-mist humidifier or saline drops for stuffy noses.
  • Dose fever or pain medicine by weight and follow the label or your clinician’s guidance.
  • Keep a simple log of temperatures, fluids and symptoms to share with your child’s provider.

Trust your instincts

Pediatric guidance consistently emphasizes that parents know their children best. If something feels wrong, even when you cannot name it, reach out. Seek emergency care for trouble breathing, a seizure, blue or gray lips, severe dehydration, or a child who is difficult to wake.

If you have questions about a symptom or want help planning for the next cold season, contact the practice to talk about your family’s needs. You do not have to sort through it alone.
