What is Asthma in Babies and Children?
Asthma is a common condition in childhood that causes the airways to become inflamed and narrowed, leading to wheezing, coughing, chest tightness, and breathlessness. Symptoms can be triggered by colds and other viral infections, allergens like dust or pet hair, cold air, exercise, or smoke.
While asthma can't be cured, it's usually well controlled with the right combination of preventer and reliever inhalers, along with identifying and managing individual triggers where possible.

Clinical context
A written asthma action plan helps enormously
An individualised asthma action plan from your child's doctor sets out exactly what to do day-to-day and during a flare-up, taking the guesswork out of managing symptoms.

Practical steps
Never Skip Prescribed Preventer Medication
Preventer inhalers work by reducing inflammation over time — they need to be used regularly as prescribed, even when your child feels well, not just during flare-ups.
- 1Follow the asthma action plan exactly.Use preventer and reliever inhalers as directed, and know the specific steps to take if symptoms worsen.
- 2Use a spacer device for inhalers.Spacers help ensure medication reaches the lungs effectively, especially in young children.
- 3Identify and reduce triggers.Common triggers include dust, pet dander, smoke, and cold air — reducing exposure where possible can help.
- 4Keep the reliever inhaler accessible.Make sure it's always available at home, school, and anywhere your child spends time.
- 5Attend regular asthma review appointments.Regular check-ins help keep the management plan up to date as your child grows.
