Snot, Sniffles & What It All Means

Your baby’s first cold can feel like a milestone — and not the fun kind like rolling over or that first gummy smile. Instead, it’s tissues everywhere, tiny sneezes, restless nights, and you wondering “Is this normal?”

The truth is: colds are part of growing up. They’re usually mild, but they can feel bigger because bub is still so little. And here’s the surprising part: that snot pouring out of their nose? It’s not just mess — it’s actually giving you clues about what’s going on.

So, What’s a Cold?

Colds are viral infections of the upper airways. In babies, common viruses like RSV and rhinovirus cause the classic blocked/runny nose, sneezes, mild fevers, watery eyes, and fussiness.

Because babies mostly breathe through their noses, even a little congestion can affect feeding and sleep. That’s why their first cold can feel like such a mountain.

Why Snot Matters

Snot is bub’s superhero sidekick. It:

Traps germs and dust
Keeps the nose moist
Flushes out invaders

As bub’s body fights back, the colour and texture of mucus changes. Instead of panicking at the sight of green slime, think of it as your baby’s immune system flexing its muscles.

The Colour Guide

Clear – Normal. Can be allergy-related or just the body’s daily housekeeping.
White – A viral infection slowing things down. Thick, milky mucus = immune system working.
Yellow / Green – White blood cells at work. The colour shift means bub’s immune system is doing its job.
Pink / Red – A little blood from irritation (dry air, suctioning, rubbing).
Brown – Usually dried blood or dust.
Black – Rare. Can mean fungal infection or pollution exposure. See a doctor promptly.

Remember: yellow or green doesn’t mean antibiotics. Look at the big picture — how bub is feeding, breathing, and acting.

Caring for Bub at Home

Cuddles & comfort – Sometimes the best medicine is you.
Fluids – Offer smaller, more frequent feeds. Wet nappies show hydration is on track.
Clear those noses – Saline drops or spray +/- a gentle suction can help bub breathe and feed easier.
Steam & moisture – Humidifiers or sitting in a steamy bathroom can often help loosen mucus.
Keep them comfortable –Help ease those body aches and discomfort that come with colds by using paracetamol or ibuprofen. Always follow the instructions on the packet for safe dosing, and use your Sick Sense Medication Tracker to stay on top of times and amounts.

When to Call the Doctor

Trust your Sick Sense, and watch for:

Bub under 3 months with any cold symptoms
Breathing that looks hard (fast, noisy, chest sucking in, flaring nostrils)
Bub not feeding or showing signs of dehydration (fewer wet nappies)
Persistent fever lasting more than 48 hours
Bub under 3 months with a fever
Rash that doesn’t fade when pressed
Extreme sleepiness, floppiness, or inconsolable crying
Black mucus, heavy bleeding, or worsening green/yellow snot with fever

Most colds come and go with rest, fluids, and comfort.

Trust your instincts, back yourself, and know that with your Sick Sense, you’re never flying blind.
