Wheezing in Babies & Toddler Asthma: Care Guide | Parenting Hub
Wheezing in babies is often viral. Repeated wheeze with colds can be early asthma. Here's how to recognise and act.
A first wheeze with a cold is often viral and not asthma. Repeated wheeze with colds — especially with a family history — can be early asthma. Either way, breathing changes need attention.
What is wheeze?
A high-pitched whistle on the OUT breath — best heard with an ear near the mouth, or by your GP with a stethoscope. Different from snuffle (nose), grunt (effort) and stridor (in-breath, usually croup).
Common causes by age
- Under 12 months: usually bronchiolitis (see RSV article)
- 1–5 years: viral-induced wheeze (with colds) — common, often outgrown
- Asthma: repeated episodes of wheeze, cough at night/early morning, with exercise or allergens
- Foreign body inhaled: sudden onset wheeze/cough out of nowhere — ED
Care and asthma action
- If your child has been prescribed a reliever (salbutamol/Ventolin), use through a spacer + mask, 4–6 puffs, one breath each, repeat after 4 hours
- If breathing not improving in 20 minutes after first dose — call ambulance
- Keep an Asthma Action Plan from your GP for any wheezy child
- Avoid smoke exposure, dust, strong perfumes
When to seek help
- Fast breathing (>60/min under 1; >40/min over 1)
- Ribs sucking in, nostrils flaring, head bobbing
- Can't speak in sentences or feed because of breathing
- Blue lips or grey skin — 000
- Not improving after 6 puffs of reliever — call ambulance
Common questions
Does wheeze mean my child will have asthma?
Not necessarily. Many toddlers wheeze with viruses and grow out of it. A persistent pattern with family history is more suggestive — your GP can guide assessment.
