Baby Cold: Symptoms, Care & When to Worry | Parenting Hub
Babies catch around 6–10 colds a year. How to ease symptoms safely, what NOT to give, and the red flags that mean more than just a cold.
Babies catch a lot of colds in their first two years — it's how their immune system learns. Most are mild, but a small baby with a cold needs careful watching.
What's normal
Babies typically catch 6–10 colds a year, more if in daycare or with older siblings. Symptoms include blocked or runny nose, mild cough, sneezing, slightly raised temperature, and unsettled feeding or sleep. Most colds last 7–10 days, with a peak around days 2–3.
What helps
You can't shorten a cold, but you can keep baby comfortable.
- Saline nose drops or spray, then a bulb suction or NoseFrida, before feeds and sleeps
- Smaller, more frequent feeds — congested babies tire easily
- Upright cuddles to help breathing
- A humidifier or steam from a hot shower in the bathroom
- Plenty of breast or formula milk; water for babies over 6 months
- Paracetamol over 1 month or ibuprofen over 3 months for discomfort or fever
What to avoid
Several products marketed for colds aren't safe for babies.
- Cough and cold medicines — not recommended under 6 years
- Vapour rubs containing camphor or menthol — not safe under 2 years
- Honey — never under 12 months (botulism risk)
- Antibiotics — colds are viral, antibiotics won't help
When to see a doctor
See your GP if symptoms last more than 10 days, get worse rather than better, baby is feeding poorly, or you're worried.
When to seek urgent care
Difficulty breathing, fast breathing, ribs sucking in, blueness around lips, fever in a baby under 3 months, or baby is floppy or unresponsive — call 000 or go to ED.
When to seek help
- Fast breathing or working hard to breathe
- Ribs sucking in with each breath
- Bluish lips or skin
- Fever in a baby under 3 months
- Fewer than half normal wet nappies
- Cough getting worse after day 5–6
Common questions
How can I tell a cold from RSV?
RSV often starts like a cold but worsens after a few days with wheezing, fast or laboured breathing. Any breathing difficulty needs urgent review.
When should I worry?
Any breathing difficulty, signs of dehydration, fever in a baby under 3 months, or a baby who is unusually drowsy or unresponsive needs urgent assessment.
