Learning to blow their nose means a child has to breathe out through the nose while keeping the mouth closed, then do it one nostril at a time. No health authority sets a precise age: the skill comes gradually, often after the age of 2, as the child learns to control their breath. Blowing games lay the groundwork well before that.
Geneva’s child health service sums it up: children should be taught to blow their nose “as soon as possible” and encouraged to do so. Until then, it is the adult who clears the nose, especially before meals and naps.
Why blowing their nose is hard for a toddler
Blowing your nose seems simple to an adult. For a 2-year-old, it is a brand-new kind of coordination. They have to close their mouth, breathe in, then push the air out through the nose only. Many children start by blowing through the mouth, or by sniffing instead of blowing.
It relies on three skills that develop over time:
- feeling the difference between blowing through the mouth and blowing through the nose;
- controlling the strength of the breath, neither too weak nor too forceful;
- holding the tissue without pinching both nostrils at once.
As with other everyday skills, children mostly learn by imitation. They watch the adult, then have a go themselves. This is the principle of learning through imitation, at work from the very first months.
Teaching a toddler to blow their nose: what age to start?
There is no official age. The hygiene guides we consulted, from Quebec and Geneva alike, describe it as something to teach as soon as the child is able, without giving a threshold. Quebec’s Ministry of Health specifies that the adult carries out the steps for the child or helps them, depending on their age.
In practice, you can keep three rough phases in mind:
- Before 2 years: the adult wipes and clears the child’s nose. You can already name what you are doing and show how to blow.
- Between 2 and 3 years: the child discovers blowing through the nose through games. They hold the tissue with help.
- From around 3 years: many children blow their nose with a reminder, then on their own. The result is often still far from perfect.
These stages are guidelines, not rules. A 4-year-old who still sniffs is nothing to worry about. A permanently blocked nose, snoring or constant mouth breathing, however, are worth mentioning to your doctor.
Blowing games to prepare the skill
Before blowing their nose, a child needs to discover that they can breathe out through it. Play is the most effective way, because it takes away all the pressure. A few simple ideas:
- The feather or cotton wool: put a small piece of cotton wool on the table. Your child moves it along by blowing through their nose, mouth closed.
- The mirror: hold a small mirror under their nose. It mists up when they blow through their nose. That is instant visual feedback.
- The pinwheel: make a small pinwheel spin by blowing first through the mouth, then through the nose.
- One nostril closed: gently press on one nostril and let them blow through the other, onto a feather or a piece of paper.
Play these games when the nose is clear, not in the middle of a cold. They last a few minutes and stop as soon as your child loses interest.
How to teach your child to blow their nose, step by step
The respiratory hygiene guide from Quebec’s Ministry of Health, 2025 edition, describes a precise technique. You blow gently, one nostril at a time, pressing on the opposite nostril. The aim is to stop secretions travelling up into the Eustachian tubes, which connect the nose to the ears.
The steps to show
- Take a paper tissue and hold it in front of the nose.
- Close the mouth.
- Press on one nostril with a finger, over the tissue.
- Blow gently through the other nostril.
- Switch sides, then wipe the nose.
- Throw the tissue in the bin straight away.
- Wash hands.
Common mistakes
- Blowing very hard through both nostrils at once: it is uncomfortable and not much use.
- Keeping a used tissue in a pocket for later.
- Using just one tissue that is too small, leaving fingers in contact with secretions.
The Quebec guide recommends using enough tissues so that fingers do not touch the secretions. It also suggests a bin lined with a bag, ideally a no-touch one.
The tissue, then handwashing
Blowing your nose is part of a wider set of hygiene habits. After each nose-blow, washing hands limits the spread of winter viruses. The Quebec guide also expects this from the adult helping the child to blow their nose. This habit builds up at the same time as the child learns to wash their hands on their own.
The same guide reminds us what to do without a tissue. You cough or sneeze into the crook of your elbow or upper arm, rather than into your hand. Show it through play: children happily copy this slightly theatrical gesture.
When your child cannot blow their nose yet
Until your child can blow, it is up to the adult to clear their nose. Geneva’s child health service advises doing so before a meal and before a nap. A clear nose makes breastfeeding, bottle feeds and falling asleep easier.
For the youngest, rinsing the nose with saline solution is an option, but not as a routine. The Geneva leaflet mentions 3 ml per nostril up to 6 months, then 5 to 10 ml after that. It keeps this for very runny or very congested noses, and then encourages the child to blow their nose. Choosing a nasal aspirator is covered in our guide to the baby nasal aspirator.
Encouraging independence without making it a chore
Blowing their own nose joins the other small everyday achievements. Just like getting dressed on their own or tidying up their toys, children move forward in small steps, with an adult who shows them and praises them.
- Leave tissues within reach, in a small box they can open by themselves.
- Put an easy-to-reach bin next to it.
- Offer rather than insist: “Do you want to blow, or shall I help you?”
- Praise the effort, even when the result is only partial.
A child whose nose is wiped by surprise, roughly, often ends up running away from the tissue. Letting them know before you act makes a big difference.
Key takeaways
Learning to blow their nose happens without a set timetable. Blowing games through the nose prepare the skill. Next, you show one nostril at a time, throw away the tissue and wash hands. Until your child manages it, the adult takes over, especially before meals and naps.
