How to Clear Your Baby's Blocked Nose Safely

One of the biggest surprises for new parents is just how often babies get blocked noses.

In fact, it's perfectly normal for babies and toddlers to catch several colds each year, especially once they begin childcare or spend time around older siblings. Unlike adults, however, babies can't simply grab a tissue and blow their nose.

Because their nasal passages are tiny, even a small amount of mucus can make them sound incredibly congested. A blocked nose can also make feeding more difficult, disturb sleep and leave everyone feeling exhausted.

The good news? There are simple ways to help clear your baby's nose at home. One of the most effective approaches is a simple two-step routine:

1. Use saline to help loosen nasal mucus.
2. Gently remove the loosened mucus using a nasal aspirator.

It's straightforward, quick and can make a big difference when your little one is struggling with congestion.

Why do babies get blocked noses so easily?

Babies are obligate nose breathers for the first few months of life, meaning they naturally prefer breathing through their nose, particularly while feeding. Their nasal passages are also incredibly small. That means mucus from a common cold, dry air or mild irritation can quickly make them sound noisy or congested.

You may notice your baby:

• sounds snuffly or congested
• struggles to feed comfortably
• wakes more frequently overnight
• breathes noisily while sleeping
• has visible mucus around their nostrils
• seems unsettled despite otherwise being well.

While it can sound alarming, a blocked nose is usually a normal part of many viral illnesses.

Newborns vs Older Babies: Does It Make a Difference?

In the early weeks, newborns are obligate nasal breathers. That means they rely almost entirely on their nose for breathing, especially during feeds. They haven't yet learned to switch to mouth breathing when their nose is blocked, which is why even a small amount of congestion can feel like a big deal in those first weeks.

This is also why newborn snuffles and clogged noses can interfere with breastfeeding or bottle feeding so noticeably. If your newborn is pulling off the breast repeatedly or seems frustrated during feeds, a partially blocked nose could be contributing.

As babies get older, they become better at adapting, but congestion can still disturb feeds and sleep well into toddlerhood. The same two-step approach works across ages: saline first, then gentle suction.

If you're preparing for a new baby, it's worth adding saline drops and a nasal aspirator to your list of early essentials. Congestion in the newborn period is common, and having the right tools at home from day one can save a lot of stress.

Signs your baby's nose may need clearing

Not every sniffle needs intervention. However, clearing your baby's nose may help if congestion is making everyday activities difficult. Signs include:

• They're finding it difficult to breastfeed or bottle feed.
• They continually pull away from feeds to breathe.
• They seem frustrated or unsettled because of congestion.
• You can see mucus around the nostrils.
• Their sleep is being interrupted by a blocked nose.

If your baby seems comfortable, is feeding well and is breathing easily, they may not need any assistance.

How to Suction Your Baby's Nose: Step-by-Step

Here's the part many parents say nobody told them. Trying to suction thick mucus on its own isn't always the easiest approach. Instead, many health professionals recommend a simple two-step process.

Step 1: use saline first

Saline nasal drops or spray can help moisten and loosen mucus inside your baby's nose. Giving the saline a moment to work can make removing mucus much easier. Always follow the instructions supplied with the saline product.

Step 2: gently remove the loosened mucus

Once the mucus has loosened, a manual nasal aspirator such as the Frida Baby NoseFrida SnotSucker is designed to help remove nasal mucus. Unlike traditional bulb syringes, NoseFrida allows the parent to control the suction themselves.

Its disposable hygiene filter is designed to help stop mucus travelling through the tube, so parents can confidently clear their baby's nose without worrying about what they're imagining might happen.

The goal isn't to remove every tiny bit of mucus. It's simply to help clear enough mucus so your baby can feed, sleep and breathe more comfortably through their nose.

Common mistakes parents make

Do snot suckers actually work?

This is one of the most common questions parents ask. The answer is simple: a nasal aspirator is designed to help remove loosened nasal mucus from babies who can't blow their own nose. When used after saline, many parents find it much easier to clear congestion than relying on wiping the outside of the nose alone.

The key isn't the device on its own, it's using the right technique. Saline first. Then suction.

Is it safe to use a nasal aspirator?

When used according to the manufacturer's instructions, a nasal aspirator is designed for gentle removal of nasal mucus. Always:

• be gentle
• avoid forcing the tip into the nostril
• stop if your baby becomes distressed
• clean the device after each use.

If you're unsure whether your baby's congestion is normal, speak with your GP, maternal and child health nurse or another healthcare professional.

Nobody told me winter would sound so noisy

Blocked noses are one of the most common challenges parents face during winter. The noisy breathing, interrupted feeds and sleepless nights can feel overwhelming, particularly during your baby's first cold.

The reassuring news is that congestion is a normal part of growing up. Understanding how to gently suction your baby's nose, and knowing when to seek medical advice, can help you feel much more confident the next time the sniffles arrive.

Frequently asked questions

How do you clear a newborn's blocked nose?

The same two-step approach works for newborns: use saline drops first to moisten and loosen mucus, then gently suction with a nasal aspirator designed for babies. Because newborns are obligate nasal breathers and rely heavily on their nose during feeds, clearing even a small amount of mucus can make a noticeable difference. If you're uncertain about your newborn's symptoms, speak with your GP or maternal and child health nurse.

How do you unblock a baby's nose naturally?

Saline nasal drops or spray are a gentle first option. They help moisten and loosen mucus without any medication. Running a cool-mist humidifier in the room can also help keep the air from becoming too dry, which may contribute to congestion. Keeping your baby upright during feeds can also help. Always speak with your healthcare professional if you're unsure about the best approach for your baby.

What causes newborn nasal congestion?

Newborn nasal congestion is common and can be caused by a viral illness such as a cold, dry air, environmental irritants or simply the fact that their nasal passages are very small. Some newborns also have residual fluid in their nasal passages after birth, which usually clears on its own. If congestion seems severe, is accompanied by a fever or you're worried, check in with your GP or midwife.

Can I use a nasal aspirator on a newborn?

The NoseFrida is suitable from birth. Always follow the manufacturer's instructions and speak with your healthcare professional if you're unsure about your newborn's symptoms or care.

How often should I clear my baby's nose?

Only when congestion is making feeding, sleeping or breathing through the nose more difficult.

Why use saline first?

Saline helps loosen mucus, making it easier to remove with gentle suction.

My baby hates having their nose cleared. Is that normal?

Yes. Many babies dislike the process, but it is usually over quickly. Staying calm and working gently can help.

Can clearing my baby's nose cure their cold?

No. A nasal aspirator is designed to help remove nasal mucus. It does not treat or cure the underlying viral illness.
