Bronchiolitis in Babies

Stay for the one thing that helps most when your baby can't feed.

What is bronchiolitis?

Here's the thing, bronchiolitis isn't just a bad cold. It's a virus, usually RSV, that hits the tiniest airways in a baby's lungs. Those tubes are thinner than a strand of cooked vermicelli, so when they swell and fill with mucus, breathing becomes hard work. In an adult, the same virus is just a cold. In a small baby, it's a different story. It peaks in winter, when families crowd indoors and RSV travels on hands.

Each age looks different

Now, the part most people miss, bronchiolitis looks different by age. Under three months, it's the highest-risk group, and the signs can be sneaky: feeding less, sleepier, even pauses in breathing. Between three months and a year, you get the classic picture, runny nose, then cough, fast breathing, slower feeds. One to two years, it's usually milder, like a heavy cold with a wheezy cough. Over two? Same virus, but mostly just a cold.

Cold or bronchiolitis?

So how do you tell a plain cold from bronchiolitis? At first you can't. Both start with a runny nose and a slight cough. What separates them is what happens next. A cold leaves your baby feeding normally and breathing comfortably between sneezes. With bronchiolitis, breathing gets faster and more effortful, and the baby keeps coming off the breast or bottle to catch their breath. Counting breaths is the most reliable way to judge speed, and if you're unsure, ask your doctor.

Worst days: day 3 to 5

What surprised me is that bronchiolitis doesn't hit its worst right away. It starts like a cold, and then around day three to five, the cough deepens, breathing gets noisier, and feeding gets harder. That's the window when you need to watch most closely. The good news? Most babies turn the corner after that. But the cough can hang around for about three weeks, which feels like forever when you're listening to it every night.

Feeding is your best gauge

Think about it. If your baby can't breathe through a blocked nose, they can't feed well. And if they're not feeding, they're getting dehydrated. That's why doctors ask about feeds before anything else, always. You don't need to count breaths or measure oxygen at home. You just need to watch whether your baby is drinking and how many wet nappies you're changing. That's the single most practical thing you can track.

Keep a nappy tally

Here's a trick that sounds too simple, but it works. Take a piece of paper, stick it on the fridge, and tick every wet nappy and every feed with the time. Compare it with a normal day. If your baby is taking much less than usual, or you've got a dry nappy for twelve hours, call your doctor the same day. The tally also gives the doctor exact facts instead of 'she's not eating much', and that makes the whole conversation easier.

Home care that helps

Now, what actually helps at home? Offer smaller feeds more often, breast or formula only, and under six months, nothing else. No water, no gripe water, no ghutti, no herbal bits. Clear the nose just before a feed using saline drops, half a level teaspoon of salt in two hundred fifty mils of boiled and cooled water. Keep your baby upright while awake, like on your lap while you sip your chai. And for sleep, flat on their back in a bare cot, never propped up.

Suck the nose, then feed

There's one line from the post that stuck with me: 'Suck the nose, then feed. Not the other way round.' It sounds obvious, but when you're tired and the baby is crying, it's so tempting to just shove the bottle in. The problem is, a blocked nose means they can't breathe and swallow at the same time. Clear the nose first, give it a moment, then feed. That tiny change in order can make a world of difference.

Do those treatments help?

So what about nebulisers, antibiotics, and cough syrups? Here's the honest answer. Bronchiolitis is caused by a virus, so antibiotics don't help unless a doctor finds a separate bacterial infection. The nebulisers that work for asthma usually don't make much difference in typical bronchiolitis, which is why many doctors don't use them routinely, that decision belongs to your doctor. And over-the-counter cough and cold medicines are not for children under six.

When to go now

Now, the part nobody wants to think about, but everyone needs to know. Go to emergency if your baby is grunting, or their tummy or chest sucks in under the ribs with each breath, or there are pauses in their breathing, or their lips, tongue, or skin look blue or grey. On darker skin, check the lips, gums, palms, and inside the eyelids. If your baby is floppy and won't wake, or feeding far less than usual, see a doctor the same day.

The one order that matters

So here's the one thing to take away from all of this. When your baby has bronchiolitis, the single most useful habit is to clear their nose before every feed, not after. Suck the nose, then feed. It sounds small, but it's the difference between a baby who can actually drink and one who gives up after two sips. Try it tonight, and you'll see what I mean.
