How To Help Toddler With Runny Nose: Saline First, Then Suction — In That Exact Order

One of the best ways to help your toddler is by using saline nasal drops or a saline solution. These drops help moisten the inside of the nose and loosen excess mucus, making it easier to remove.
- Using saline nasal drops or sprays is a safe and effective way to clear your child’s nasal passages and help them breathe easier.
Apply 2 to 3 drops into each nostril, wait one minute, then suction gently with a bulb syringe or nasal aspirator. This is safe at any age. 1
You can also make saline at home. Mix half a teaspoon of salt into 8 ounces of warm water. Make a fresh batch each day. Do not reuse yesterday’s solution.
- You can gently suction the mucus with a nasal aspirator or bulb syringe, especially for younger children who can’t blow their noses yet. This simple remedy can reduce nasal congestion and help your child breathe easier, helping your child’s body feel more comfortable and function better during illness.
Do not suction more than 2 to 3 times per day. Overuse causes the nasal lining to swell and makes congestion worse.
- Using a cool mist humidifier in your child’s room adds moisture to the dry air, which can prevent irritation of the nasal passages and soothe a stuffy or runny nose.
- Elevating your child’s head slightly while they sleep with an extra pillow can help drain mucus and reduce nasal congestion, making it easier for them to breathe at night and rest.
- Simple home remedies like a warm shower or steam inhalation can loosen mucus and ease nasal congestion. Just sitting with your toddler in a steamy bathroom for 10 to 15 minutes can provide relief. 2
- Additionally, natural cold remedies for kids include maintaining a balanced diet rich in vitamin C, which can support your child’s immune system during cold and flu season.
Other steps that help:
- Keep your toddler away from cigarette smoke and strong odors. Both dry out and irritate the nasal lining.
- Try a warm damp cloth on your toddler’s nose and cheeks for a few minutes. It soothes irritated skin and loosens surface mucus.
A large 2024 clinical trial from the European Respiratory Society found that hypertonic saline nasal drops reduced the duration of cold symptoms in young children by 2 full days and reduced household spread of the virus. 3
How to teach your toddler to blow their nose?

Most toddlers learn to blow their nose between ages 2 and 3. Blow your own nose in front of them and ask them to copy. Place a tissue under their nostril and ask them to “push air out like you’re blowing out a candle.” Praise every attempt. Keep one nostril covered while they blow, then switch. It takes practice but saves you from suctioning once they get it.
Does A Runny Nose Turn Into A Cough?

Excess mucus from a runny nose drains down the back of your toddler’s throat when they lie flat. This is called postnasal drip. It irritates the airway and triggers the cough reflex. 4
The cough is usually worse at night because your toddler spends more time lying flat. Clearing the nose with saline and suction before bed reduces how much mucus drains and how much your toddler coughs. For a full guide on managing this, read our article on what to give a toddler for a cough at night.
What Does The Mucus Color Tell You?
Mucus color does not tell you whether your toddler needs antibiotics. Clear mucus usually appears at the start of a cold. Yellow or green mucus appears later as the immune system clears the virus. This is normal. 5
One exception matters: if the runny nose is coming from only one nostril and has a foul smell, do not wait. This can mean your toddler has pushed a small object into their nose. The infected discharge from a nasal foreign object can drain into the throat and cause bad breath in toddlers as well. If you notice both a one-sided foul-smelling runny nose and unusual breath odor together, that combination is a strong signal to see your pediatrician the same day.

How To Fix Redness From Wiping Nose?

To help with redness from wiping your toddler’s nose, use very soft tissues or a damp, soft cloth and gently clean the skin with warm water, avoiding harsh soaps. After patting dry, apply a thin layer of plain petroleum jelly or a gentle, fragrance‑free moisturizer to the skin around (not inside) the nostrils to act as a protective barrier and reduce chapping.

What Can I Give My Toddler For A Cough And Runny Nose?
When your toddler has a cough and runny nose, it’s important to focus on safe and effective ways to ease their symptoms. The American Academy of Pediatrics specifically recommends avoiding cold medicines in children younger than six due to safety concerns.6
- Saline nasal drops or sprays: These help clear mucus from your child’s nose, easing both runny and stuffy nose symptoms.
- Humidifiers: Using a cool-mist humidifier in your toddler’s room adds moisture to the air, which can soothe irritated nasal passages and ease coughing caused by dryness.
- Honey: For toddlers over one year old, a small amount of honey can soothe the throat and reduce coughing. However, honey should never be given to children under 12 months due to the risk of botulism.
- Hydration: Encourage your child to drink plenty of fluids like water, warm broths, or diluted fruit juices to thin mucus and keep the child comfortable.
- Rest and comfort: Make sure your child gets plenty of rest and feels comfortable, which helps their body fight off illness.
What Causes Runny Nose In Toddlers?

A runny nose in toddlers can be caused by several factors, ranging from common infections to environmental triggers. Monitoring your child’s symptoms, such as the presence of a runny nose, congestion, or other symptoms, can help determine the cause and best treatment for your child’s nasal congestion.
Main causes:
- Common cold (rhinovirus): The most frequent. Starts with clear mucus, then thickens.
- RSV (respiratory syncytial virus): Looks like a cold but can be more severe in young children. 7 RSV is the leading cause of respiratory hospitalization in children under 2. Watch for fast breathing or labored breathing alongside a runny nose.
- Allergies: Triggered by dust mites, pollen, pet dander, or mold. Allergy runny noses are clear and watery with no fever.
- Cold air (vasomotor rhinitis): Breathing cold air triggers a nerve reflex that causes the nose to run within minutes. It stops 15 minutes after coming indoors. No treatment needed.
- Teething: Can cause mild clear discharge temporarily.
- Foreign object: One-sided runny nose with a foul smell. See your pediatrician immediately.
- Sinusitis: Thick colored mucus lasting more than 10 days with facial pain and fever. Needs a doctor visit.
Can A Runny Nose Lead To An Ear Infection?
Yes. This is one of the most important complications parents miss. When mucus blocks the eustachian tube (the small passage connecting the nose and middle ear), bacteria can become trapped and cause an ear infection. 8 The AAP notes that 5 to 10% of toddler colds lead to an ear or sinus infection.
Can Cold Weather Cause A Runny Nose In A Toddler?
Cold weather can cause a runny nose in toddlers. When your child is exposed to cold air, their nasal passages may become irritated and produce extra mucus as a natural defense. This mucus helps to warm and humidify the air they breathe in, protecting the delicate tissues inside the nose.
Sudden changes in temperature, such as going from a warm indoor environment to the cold outdoors, can also trigger a runny nose. This is because the body tries to keep the nasal passages moist and prevent them from drying out in the chilly, dry air.
How To Stop A Runny Nose From A Weather Change?
To stop a toddler’s runny nose caused by weather changes, use a saline nasal spray to moisten the nasal passages and a suction bulb or aspirator to remove mucus, particularly before feeding or sleeping. Use a cool-mist humidifier in their room to keep the air moist, and ensure they stay hydrated with water or warm broths.
- Dress Your Child Appropriately: Make sure your toddler wears layers to stay warm during cold weather. Covering their head with a hat and protecting their face with a scarf can reduce exposure to chilly air that irritates nasal passages.
- Use a Humidifier Indoors: Cold weather often means dry indoor air due to heating systems, which can worsen nasal irritation. Placing a cool-mist humidifier in your child’s room helps maintain optimal air moisture and supports respiratory health by keeping your child’s nasal passages moist and reducing the runny nose.
- Limit Outdoor Exposure in Extreme Weather: When temperatures drop significantly or the air is very dry, try to limit the time your toddler spends outside. If going outdoors is necessary, keep outings short and ensure your child is well protected against the cold.
- Keep Nasal Passages Moisturized: Applying saline nasal drops regularly can help maintain moisture inside the nose and loosen mucus, making it easier for your child to breathe comfortably despite the weather changes.
- Create Warm, Steamy Environments: Running a hot shower to create steam in the bathroom and spending time there with your toddler can loosen mucus and relieve nasal congestion caused by cold air.
- Avoid Irritants: Keep your child away from smoke, strong perfumes, or other irritants that can worsen nasal symptoms, especially when the weather is already irritating their nose.
Should I Take My Child To The Doctor For A Runny Nose?
Most runny noses in kids are caused by common colds or minor allergies and usually improve on their own with home care. However, there are times when you should consult your pediatrician to ensure your child receives the right care.9
You should take your child to the doctor if:
- The runny nose lasts longer than 10 days without improvement, which may indicate a bacterial infection or other persistent symptoms.
- Your child has a high fever, especially if it lasts more than 3 days.
- There are signs of difficulty breathing, such as wheezing, rapid breathing, or persistent coughing.
- Your child shows signs of dehydration, like dry mouth, no tears when crying, or fewer wet diapers.
- The nasal discharge is thick, yellow, or green and is accompanied by facial pain or swelling, which could signal a sinus infection.
- Your child has a history of asthma or other chronic respiratory conditions, which may require special attention.
- You notice a blue tint around your child’s lips or face, which is a medical emergency requiring immediate attention at the nearest emergency department.
Seek medical attention if your child experiences a high fever, signs of dehydration, or trouble breathing alongside nasal congestion.
Always trust your instincts as a parent. If you feel your child may need medical attention, it’s best to contact your pediatrician for guidance. Early evaluation can help prevent complications and provide peace of mind.

Frequently Asked Questions
How long does a toddler’s runny nose last?
Most runny noses caused by a viral cold last 7 to 10 days. The AAP notes symptoms can last up to 14 days in toddlers. If it lasts longer than 10 to 14 days or keeps getting worse, call your pediatrician.
Is yellow or green mucus a sign my toddler needs antibiotics?
No. Yellow or green mucus is a normal part of the immune response clearing a viral infection. The AAP confirms this is not a sign of bacterial infection on its own. Antibiotics only work against bacteria; they do not help with viral colds and should not be requested for a runny nose alone.
Can I use a nasal aspirator every day?
Yes, but do not overuse it. Suction 2 to 3 times per day, maximum. Too-frequent suctioning can cause the nasal lining to swell, which makes congestion worse. Always use saline drops first to loosen the mucus before suctioning.
What is the difference between a runny nose from allergies and a cold?
A cold-related runny nose usually comes with fever, sore throat, or cough and clears up in 7 to 10 days. An allergy-related runny nose is typically clear and watery, comes with sneezing or itchy eyes, does not include fever, and comes back around the same triggers or seasons. If symptoms last more than 2 weeks and match a pattern, see your pediatrician.
Should I keep my toddler home from daycare with a runny nose?
A mild runny nose with no fever does not require keeping your toddler home. The AAP recommends keeping children home if they have a fever above 38°C, or if they are too sick to participate in normal activities. A clear runny nose on its own, with your toddler acting and eating normally, is not a reason to miss daycare.
Should I Give My 2-Year-Old Tylenol for a Runny Nose?
No. Tylenol (acetaminophen) treats fever and pain, not a runny nose. Do not give your toddler any pain reliever unless they also have a fever above 38°C (100.4°F) or are clearly uncomfortable from a sore throat or ear pain. The CDC is clear that a runny nose alone does not require medication in children.
Where Should a Humidifier Be Placed in a Room?
Place the humidifier near your toddler’s bed but out of reach. Put it on a flat, raised surface away from walls and electronics to allow good airflow and prevent moisture damage. Make sure it is close to an outlet to avoid using long cords that can cause tripping.
