Your baby's first cold: what helps and when to see the GP
Most first colds are miserable but harmless. Here's what helps at home and the short list of signs that mean pick up the phone.
The first time your baby gets a cold, it's frightening. The snuffling, the rattly little cough, the disturbed feeds. So let's start with the reassuring bit: colds are extremely common, small children catch several a year, and once creche or older siblings are in the picture it can feel like one long cold from October to March.
A first cold usually looks worse than it is. Snuffles, sneezing, a mild cough, a mild temperature, a baby who's a bit off form. That's the normal shape of it, and it passes on its own in around a week or two.
Why a blocked nose is such a big deal for babies
Babies are nose-breathers. When your nose is blocked you switch to breathing through your mouth without thinking about it. A small baby mostly can't, so a stuffed-up nose bothers the two things you care about most: feeding and sleep.
That's why so much of managing a baby's cold is really just managing the nose.
What actually helps at home
- Saline drops or spray before feeds. A few drops of saline in each nostril loosens the congestion just when it matters most.
- A nasal aspirator. The snot sucker feels ridiculous the first time. It works. Clearing the nose before feeds and sleep makes a real difference.
- Smaller, more frequent feeds. A snuffly baby tires quickly at the breast or bottle. Little and often keeps the fluids going in.
- Keep baby upright for feeds. Gravity is on your side.
- A normal-temperature room. Not overheated. Warm and stuffy doesn't help a congested baby.
- Extra cuddles and patience. Genuinely part of the treatment.
One thing that doesn't help: antibiotics. Colds are viruses and antibiotics don't work on viruses, so don't be surprised or disappointed if the GP doesn't prescribe any.
A word on medicines
Do not use over-the-counter cough and cold medicines for young children. They're not suitable at this age.
For pain or fever relief, whether and what to give depends on your baby's age and weight. Rather than guessing, ask your pharmacist, GP or PHN, and follow the label exactly. This post deliberately gives no doses because the right answer is different for every baby.
The temperature rule that matters most
A fever is 38°C or above. And here is the one line worth memorising: in a baby under 3 months, any temperature of 38°C or above needs same-day medical advice. Not tomorrow, not "we'll see how she is in the morning". Same day. In an older baby a mild temperature with a cold is usually just part of the cold, but under 3 months the rules are stricter and that's on purpose.
Home care or help now
| You can usually ride it out | Get medical advice |
|---|---|
| Snuffles, sneezing and a mild cough | Baby under 3 months with a temperature of 38°C or above (same day) |
| Feeding okay, even if slower and grumpier than usual | Feeding much less than half the normal amount |
| Normal number of wet nappies | Fewer wet nappies than usual |
| Baby alert and rousable, having good spells between the misery | Temperature that persists, or baby getting worse rather than better |
| A mild temperature in an older baby that settles | Ear pulling with distress, or a cough lasting more than a few weeks |
If anything in the right-hand column is happening, ring the GP. That's what they're there for.
When it's an emergency
These signs mean 112 or 999, or straight to the emergency department:
- Difficulty breathing: grunting, ribs sucking in, nostrils flaring or pauses in breathing
- Blue or grey lips or skin
- A rash that does not fade when pressed with a glass
- Baby unusually floppy, or drowsy and hard to wake
- A seizure
And trust your instincts. If you're frightened, seek help. Nobody sensible will ever criticise a parent for getting a sick baby checked.
How we handle it in the app
Notice how many of the "get advice" signs are really questions about numbers. Is she feeding less? Fewer wet nappies than usual? When a baby is off form, Lullagram's feed and nappy logs give you real answers to those questions instead of a 3am guess. You can see exactly what a normal day looks like and exactly how today compares.
Which happens to be exactly what the GP will ask you.
The HSE has full guidance on colds and coughs in children if you want the official version alongside the practical.
