If your child has asthma, September is not an ordinary month.

Every year, asthma hospital stays climb after school starts, and the third week of September is the worst week of the entire year. Researchers have a name for it. They call it the September asthma epidemic, or Asthma Peak Week. It is not a rumor and it is not bad luck. It shows up in the data year after year, in the United States, Canada, the United Kingdom and other countries in the Northern Hemisphere.

Estimates suggest that somewhere between a fifth and a quarter of all childhood asthma hospitalizations happen in that one month.

Here is the part I want you to hold onto.

September is predictable. And predictable means you can get in front of it.

August is when you do that.

Why September hits so hard

Three things stack up at the same time.

Viruses. Kids return to school and child care and start trading colds within days. Rhinovirus, the ordinary common cold virus, peaks right around the return to school. Viral infections are behind the large majority of asthma flares in children. School-age kids average roughly eight colds a year, and for a child whose asthma is not well controlled, each one is an opportunity for a flare.

Ragweed. In Chicagoland, ragweed pollen starts climbing in August and peaks in early to mid September. It keeps going until the first hard frost, which in northern Illinois usually does not arrive until mid to late October. Ragweed does not just cause sneezing and itchy eyes. It triggers asthma.

Summer drift. This is the quiet one, and in my experience it is the one that catches good, attentive parents off guard. Over the summer, kids feel great. The controller inhaler gets skipped a few mornings. Then most mornings. The refill never gets picked up. Airway inflammation slowly returns underneath, while everything on the surface looks completely fine. Then the viruses and the pollen arrive at the same time, and there is no cushion left.

Any one of those three is manageable on its own.

All three landing in the same two weeks is how a child ends up in an emergency room.

Your August asthma check

Eight things. Most of them take five minutes.

1. Check expiration dates on every rescue inhaler and every nebulizer vial you own. Not just the one in the medicine cabinet. The one in the car. The one in the backpack. The one at Grandma's house. The spare in the sports bag.
2. Find out how many doses are actually left. Read the dose counter, the little number window built into the plastic part rather than the metal canister. Past the number of puffs it was built for, an inhaler keeps hissing and puffing while delivering less and less medicine. More on this below.
3. Confirm you have a spacer, and that your child uses it. A spacer, sometimes called a valved holding chamber, is not an optional accessory. It is the difference between medicine reaching the lungs and medicine landing on the back of the throat.
4. Ask for an updated written asthma action plan, dated for this school year. If the plan on file was signed two school years ago and lists a medication your child no longer takes, it is not a plan. It is a piece of paper.
5. Complete the medication authorization forms your school or child care center requires. In most settings, staff legally cannot give your child a rescue inhaler without a signed order and parent authorization on file, even if the inhaler is sitting right there in the child's cubby.
6. Restart the controller medicine now if it slipped over the summer. Controller inhalers work by reducing inflammation over time. Starting one on the first day of school does not protect your child on the first day of school.
7. Walk through the early warning signs with everyone who watches your child. The teacher. The after-school program. The grandparent doing Tuesday pickup. The coach. Ask yourself honestly whether each of them would recognize your child's first sign of trouble.
8. Plan for field trips, sports and after-school activities. This is where medication most often goes missing. A rescue inhaler that lives in the nurse's office does not help a child two hours away at a nature center.

What a written asthma action plan actually is

Parents ask me this all the time, usually a little embarrassed, as though they should already know.

An asthma action plan is a one-page document your child's provider fills out. Most versions use three color zones.

Green means your child is breathing well. It lists the daily controller medicine and the dose.

Yellow means symptoms are starting. It lists the rescue medicine, how much, how often, and what to watch next.

Red means get help now. It spells out exactly when to call the provider and when to call 911.

The plan also lists your child's known triggers, the early warning signs specific to your child, and current emergency contacts.

The Centers for Disease Control and Prevention and the American Academy of Pediatrics both recommend that children with asthma have a current written plan on file wherever they spend their days, and that it be reviewed and updated at least once a year. Your child's pediatrician or asthma specialist writes it.

If your child does not have one, or the one on file is out of date, that is the single most valuable phone call you can make this month.

The spacer thing almost nobody knows

Here is a small piece of clinical detail that even a lot of health professionals have never been taught.

A plastic spacer builds up static, the same way a balloon does when you rub it on a sweater. That static pulls the medicine onto the inside walls of the tube before your child can breathe it in. The puff went in. Some of it never came back out.

There is a fix, and it is almost silly.

Take a brand new plastic spacer apart. Wash it in warm water with a drop of ordinary dish soap. Then do not rinse the soap off. Stand the pieces up and let them air dry on their own.

The thin film of soap left behind kills the static. When researchers measured this, spacers treated that way delivered about a third more of the fine mist that reaches deep into the lungs, compared with spacers rinsed in plain water. Other work found the amount of medicine actually arriving in a child's lungs can differ by roughly twofold depending on how the spacer was handled.

Now the honest part, because I would rather you trust me than be impressed

That more medicine reaches the lungs is well established. Whether you would notice the difference during a rescue inhaler treatment is not.

Researchers tested exactly that question. In a study of 90 children with asthma, ages four to eight, removing the static from the spacer made no measurable difference to how much the airways opened after albuterol. A second study in preschoolers found the same.

The likely reason is not that the trick fails. It is that a standard dose of albuterol is already generous. You are past the point where a little more medicine buys a little more effect. Your child got plenty either way.

So where does it actually matter?

Most likely with the daily controller inhaler, the steroid one, where more medicine does translate into more benefit and you are not aiming for a maximum effect. And most likely in the youngest children, whose breaths are small enough that not much is getting through to begin with.

That is where I would spend the two minutes.

And what about drying it with a towel?

You will read in plenty of places that wiping builds static and steals the dose. Guidelines do say to air dry, and that is what I would do, because air drying is what the studies actually tested. But when researchers deliberately wiped spacers hard with a paper towel and measured what came out, they did not find a meaningful drop. So if you have been towel drying your child's spacer for two years, you have not been shortchanging them. Just switch to air drying from here.

One exception on the soap trick. Some newer spacers are made from material that does not hold static and will say antistatic on the box. Those do not need it, and the maker will tell you to rinse them normally. Read the paper that came with your device, and when in doubt, ask your pharmacist which kind you have.

The inhaler that looks full and is not

The old trick of floating the metal canister in a bowl of water does not work. Researchers have tested it directly. Inhalers float in their own unpredictable ways that have little to do with how full they are. In one study, water got into the spray hole and blocked it more than a quarter of the time. National asthma guidance and the FDA both say do not do it.

Here is why this matters so much.

An inhaler holds more spray than the number of puffs printed on the box. When the medicine runs out, the spraying does not stop. It keeps hissing and puffing on gas alone, for roughly half again as many puffs as the label promised.

It does not shut off cleanly, either. As it runs low, each puff carries a little less medicine than the one before it. There is no moment where you could hear or see the difference. And the fade is worst in rescue inhalers, which is the one you need working.

This is common, not rare. In one study, every single patient kept using their inhaler until they could no longer hear the medicine, and about three out of four had no idea how many puffs their inhaler was supposed to hold.

So read the little number window, called the dose counter. It sits on the plastic part, not on the metal canister. If it reads zero, replace the inhaler no matter how it sounds. Check the expiration date too, and go by whichever comes first.

If your inhaler has no number window, write the start date on it with a marker and keep a tally of every puff. That is the only method that actually works. Many rescue inhalers hold 200 puffs. Many daily controllers hold 120.

Two things this does not mean

Keep priming. Priming is different from testing whether an inhaler works. A brand new inhaler, one that has sat unused for two weeks, or one that got dropped needs a few sprays into the air before your child uses it. Four sprays for Ventolin, three for ProAir. Read the box for the one you have, and know that those practice sprays do count on the number window.

Keep the mouthpiece clean. If the plastic mouthpiece gets gummed up, the inhaler can stop delivering medicine altogether. Rinse it under warm water about once a week and let it air dry all the way through.

Then keep a backup. Peak Week is not the moment to find out the counter reads zero.

What to watch for, on every skin tone

Most asthma education tells parents to watch for blue lips. That advice is incomplete, and on brown and Black skin it can be actively misleading.

Color change from low oxygen is genuinely harder to see on deeper skin tones. If you are checking color, check the places where the skin is thinnest and least pigmented: the inside of the lower lip, the gums, the tongue and the nail beds. Compare against how your child normally looks, in good light.

But do not lead with color at all. Lead with effort.

Watch for skin pulling in above the collarbone, between the ribs, or under the ribcage with each breath. Nostrils flaring. The belly working visibly hard. Breathing noticeably faster than usual. A child who cannot finish a full sentence without stopping for air. A cough that will not settle, especially at night.

And one that surprises people: quiet is not always good news. If a child is wheezing loudly and then the wheeze fades while the child is working harder to breathe, that is not improvement. Air has to move to make sound.

Call 911 if your child is struggling to breathe and not improving after rescue medicine, cannot speak in short phrases, has lips or nail beds turning blue or gray, or is too sleepy or confused to respond normally.

The back-to-school health file

While you are gathering asthma paperwork, pull the rest of the file together. It is all the same trip to the filing cabinet.

• Current physical examination on the Illinois Department of Public Health Certificate of Child Health Examination form
• Immunization records meeting the 2026 to 2027 Illinois requirements
• Action plans for asthma, allergy, seizures or diabetes
• Medication authorization forms
• Updated emergency contacts
• Dietary restrictions and special health needs

Two Illinois details worth knowing.

The deadline is October 15, 2026. Under Illinois School Code, proof of the required health examination and immunizations has to be on file with the school by that date, and students who are missing required items can be excluded from school until they are submitted. Some districts set their own earlier deadlines, so check with your school.

A sports physical does not satisfy the Illinois school physical requirement. They are two different forms and two different requirements. If your child is entering preschool, kindergarten, sixth or ninth grade, or entering an Illinois school for the first time, they need the school physical on the IDPH form. If they also play a sport, that is a separate form.

Where Little Steps fits

I want to be clear about something, because it matters.

Little Steps does not replace your child's pediatrician, and I would not want to. Your pediatrician knows your child's history, writes the asthma action plan, and manages the controller medication. That relationship is the foundation.

What we do is cover the in-between.

If your child is coughing on a Saturday night and you cannot tell whether this is a cold or the start of a flare, that is a question a short telehealth visit can often answer without anyone getting in a car. If they need to be seen, I come to you, in the evenings and on weekends, after your pediatrician's office has closed. We offer in-home nebulizer treatments and rapid testing for strep, flu, RSV, COVID and mono, which helps sort out what is actually going on when a child with asthma catches something.

One specific thing for this month. If you go through the house tonight and find an expired rescue inhaler, that is often something I can take care of at a visit instead of sending you back into the phone tree. After I examine your child, I can send a refill or a new prescription when it is appropriate, and I let your pediatrician know so their records stay accurate. The same goes for a controller inhaler that ran out over the summer and never got picked back up.

Little Steps also works with child care centers on health documentation, helping directors identify missing or expiring records and prepare staff through practical health and safety education.

We serve families with children ages 3 to 19 across Oak Park, River Forest, Forest Park, Berwyn, Cicero, Maywood, Broadview and Elmwood Park, plus Austin, Garfield Park, West Loop, Humboldt Park, Logan Square, Pilsen and Little Village. If you are not sure whether we come to your street, there is a zip code checker on our FAQ page that will tell you in about three seconds.

We accept Blue Cross Blue Shield, UnitedHealthcare, Cigna and select Medicaid plans, along with self-pay, HSA and FSA.

A last thought

Nobody feels urgent about asthma in August. That is exactly the problem, and exactly the opportunity.

The work is small. Read four expiration dates. Look at a dose counter. Make one phone call about an action plan. Sign a form.

Twenty minutes in August is worth a great deal more than a Tuesday night in the emergency room in September.
