A toddler is an endless fount of unsteady, stumbling energy.

Since they tend to stumble around, toddlers grab onto all sorts of surfaces to swipe up all the dust and grime before putting their hands in their mouth.

You most likely won’t even notice all the surfaces the toddler has swiped and tasted until a couple days later.

You’ll be tucking in your ball of love, only to hear hoarse coughing like they’re about to cough up a fur-ball.

The hoarse cough keeps going and soon enough, your precious toddler is producing green snot and phlegm from the nostrils and the mouth.

You turn around to the worried spouse peeking around the door jamb and say, “I will need a young priest and an old priest”.

Hold off on the exorcism for now; first, let’s take a look at the best humidifier for toddlers cough.


At a Glance: Our Top Picks of Humidifiers for Toddlers Cough

What causes a toddlers cough?

What causes a toddlers cough?

Toddlers cough for the same reason adults do – dry, dust-filled air that clogs the sinuses and lets bacteria seep into the lungs.

As bacteria grows unchecked, the lungs start to produce a lot of mucus that’s meant to trap and push them all out through coughing; the same thing happens in sinuses but with sneezing.

If you too are weary of your toddler’s cough, read on to see what causes it and check out our best humidifier for toddlers cough.

How does dry air cause cough?

Dry room

Toddlers and adults typically breathe the same air year-round, which often contains enough moisture for the gentle mucous membrane around and inside the face.

It’s during the winter that the air dries up and we start feeling itchy and scratchy inside the throat, mouth and nose, right where there’s a gentle mucous membrane.

As the dry air chafes against everything, including our skin, it shaves off flakes of dust that accumulate all around the house to get kicked up and breathed in.

Once inside the airways, the dust triggers coughing and sneezing that kick up even more dust.

For toddlers, the itchiness and scratchiness is much worse.

It forces them to pick their nose and rub their face to spread the bacteria all around.

By the time you notice the symptoms, they had already become a chronic cough.

Don’t expect any help from the doctor regarding the symptoms right away – children's' cough is treated with antibiotics when it becomes chronic.

This is when it’s been going on between 3 and 12 weeks (and at least 8 weeks for adults).

The doctor’s trick is to listen to the cough and hear if it’s:

  • Chronic
  • Moist

If both are true, then there’s some phlegm inside bursting to get out but if the cough intensifies during night, there’s a 30% chance asthma might be involved.

How to resolve your toddler's cough

How to resolve cough

Trying to humidify the air during the winter can feel like a game of cat and mouse, with your efforts constantly being thwarted by the relentless exchange of cold and warm air.

A single gust of cold air that enters your home is enough to sap the moisture and warmth, and since the cold air sinks, also hitting the poor toddler right on the face.

Unless you have a reliable way to moisturize and warm up the air, you’ll constantly battle the cough and other symptoms of airway irritation.

By adding moisture to the air, you make it less harsh to breathe and if it’s also warm moisture, you’ll get a bit extra heat to lessen the impact of the cold gust of air.

Now that you’ve been informed of the basics of coughing, let’s move on to the qualities of the best humidifier for toddlers cough.

Key Considerations When Buying the Best Humidifier for Toddlers Cough

Small dimensions

Having the ability to quickly move the humidifier where needed means a lot to busy parents who have to juggle so many duties and gadgets; the last thing you need is a bulky humidifier.

Small dimensions will be favored in this buying guide.

8+ hour runtime

For bouts of nighttime coughing, an 8+ hour runtime humidifier is a must.

Otherwise, you’ll have to take turns with your spouse refilling it, which is not a pleasant argument to have in the middle of the night.

Keep in mind that the figure listed in the comparison table represents maximum runtime.


If you know the volume, you can estimate how long the tank will last.

Instead of getting up in the middle of the night and possibly waking your coughing toddler, you can schedule a refill when it suits you.


If you can get through the night without turning on the light fixture, you’ll get much more melatonin in your brain and a much more relaxing sleep for wrestling with your toddler the next day.

Any humidifier that has rich nightlight features gets extra kudos.
