Key points about pre-school wheeze

  • pre-school wheeze often starts with a cough or a cold
  • in most cases, you can care for your child at home
  • if your child is having trouble breathing, take them to a health professional
  • smoking increases the risk of pre-school wheeze in tamariki - don't smoke in the house or car or anywhere around your child

What is wheeze?

Wheezing is a musical, whistly sound that young tamariki make, usually when breathing out. It can also happen when they breathe in. The sound comes from the chest, not from the nose or throat.

The wheeze often starts with a cough or a cold caused by a virus.

Cough and wheezing are common when young tamariki have colds and chest infections.

Who gets pre-school wheeze

  • pre-school wheeze is common - almost 1 in 3 tamariki have it at least once
  • tamariki who are around people who smoke are more likely to get pre-school wheeze
  • pre-school wheeze is more common in premature pēpi (babies), pēpi who have had bronchiolitis or tamariki who have siblings that wheeze

Why pre-school wheeze happens

A cold may cause a narrowing of the small airways or an increase in mucus production in your child's lungs. 

The wheeze may return each time your child has a cold and can last for several days.

Is pre-school wheeze the same as asthma?

Wheezing does not usually mean your child has asthma. It's often difficult to tell whether very young tamariki have asthma, as they have narrower airways and tend to get a lot of colds.

More than half of tamariki with pre-school wheeze will grow out of it as their airways grow and develop. Some tamariki with frequent pre-school wheeze may go on to develop asthma. This is more likely if:

  • there are allergic conditions such as asthma, hay fever or eczema in the whānau
  • a child has eczema, hay fever or allergies
  • a child is growing up around cigarette smoke

Signs and symptoms of pre-school wheeze

Pre-school wheeze often starts as a cold, with a runny nose. Your child might also have:

  • fast breathing
  • extra noises when breathing in or out or both
  • a cough
  • a fever

Managing pre-school wheeze

Most tamariki with pre-school wheeze get better by themselves without any treatment.

Antibiotics do not help with pre-school wheeze.

Health professionals may give a reliever inhaler to some tamariki with pre-school wheeze. The same medicine is used for asthma. It's sometimes called a reliever or a puffer. This medicine helps open the airways to allow air to move in and out of the lungs more easily.

How to use a reliever inhaler

You will need to use the reliever inhaler with a plastic tube called a spacer and a mask. Ask your health professional to show you how to use these properly.

If your health professional has given your child a reliever inhaler:

  • give 2 puffs of the reliever inhaler, one puff at a time, using the spacer and a mask, every 4 hours
  • for each puff of the reliever inhaler, your child will need to take 6 breaths through the spacer and mask

If your child is still not improving:

  • you can give up to 6 puffs of the reliever inhaler every 4 hours

Take your child to a health professional urgently:

  • if you need to give the reliever inhaler more often than every 4 hours
  • if there is no improvement 30 minutes after giving 6 puffs of the reliever inhaler

When to get medical help for pre-school wheeze

When to see a health professional urgently

See a health professional urgently if:

  • your child's chest muscles are sucking in when they breathe
  • they're using extra neck muscles to breathe
  • they can only speak a few words at a time
  • they have flaring of the nostrils - the nostrils move out as your child breathes
  • they look pale and unwell
  • you think they've choked on something

Even if you've already seen a health professional, if your child's breathing difficulties get worse or you are worried, take your child back to a health professional.

When to call 111

Call 111 within New Zealand (use the appropriate emergency number in other countries) and ask for urgent medical help if your child:

  • is blue around the mouth
  • is struggling to breathe
  • is becoming very sleepy and not easy to wake up
  • is floppy

Signs That Children Are Struggling To Breathe

Caring for your child with pre-school wheeze at home

Encourage plenty of fluids and let your child eat if they want to.

Tamariki with pre-school wheeze may not be able to drink as much as usual - offer smaller amounts more often.

Give your child as much rest as possible.

Keep your child's environment smoke-free and vape-free.

If your child is miserable and upset, you can give paracetamol - you must follow the dosage instructions on the bottle. It is dangerous to give more than the recommended dose.

Keep your child home from school or daycare until they have recovered.

Hospital care for pre-school wheeze

Help with breathing and getting enough fluids

Tamariki with more serious pre-school wheeze may need to go to hospital. Sometimes tamariki need help with their breathing. This might include extra oxygen through small soft plastic tubes that fit into your child's nose, or a breathing mask.

Other medicines

Your child may need other medicines that they breathe in, or sometimes medicines through an IV line (cannula).

IV Line (Cannula)

Preventing pre-school wheeze

Smoke-free environment

Keep your child's environment smoke-free. If you want to give up smoking:

A warm house

Keeping the house warm, dry and well-insulated will also decrease your child's risk of developing pre-school wheeze.

Keeping Your Home Warm & Dry
