**Yes—explaining his asthma and asking the teacher to get help if symptoms appear is appropriate.** A brief message with specific signs and a clear next step gives her something practical to act on.

You can reasonably ask her to:

- Take his report of breathing trouble seriously and arrange prompt help from the nurse or designated staff member.
- Act if she notices worsening coughing, wheezing, difficulty breathing, or difficulty participating in normal activities.
- Have the school contact you if he becomes unwell or needs to come home.

The boundary is the level of care involved. Constant observation, scheduled breathing assessments, and treatment decisions need an agreed school health plan and appropriately trained staff. Medication administration should follow that plan and school policy.

Because his attacks can become severe, **contact the school nurse or office as well as the teacher**. Ask who handles asthma symptoms, who covers when the nurse is absent, and what paperwork is needed for his prescribed reliever inhaler and spacer. These are questions the [CDC specifically recommends parents ask schools](https://www.cdc.gov/healthy-schools/media/pdfs/P4HS_Asthma_1.pdf).

Arrange a written **asthma action plan** with his clinician and give the school a copy. It should specify his warning signs, prescribed treatment, and when to call you or emergency services. [NHLBI’s school guidance](https://www.nhlbi.nih.gov/files/docs/resources/lung/NACI_ManagingAsthma-508%20FINAL.pdf) recommends keeping this plan on file and making sure relevant staff know it.

You could email:

> Hi [Teacher],
>
> [Name] has asthma that is usually triggered by colds. He has a cough and cold today, and these illnesses can sometimes cause significant breathing problems for him.
>
> If you notice his cough worsening, wheezing, difficulty breathing, or that he seems increasingly unwell—or if he tells you his breathing feels difficult—please arrange prompt help through the school’s health procedure. Please have the school contact us if he needs assessment or collection; we’re available at [numbers].
>
> I’ll also contact the nurse/office to confirm his asthma plan and medication arrangements. Thank you for helping us look after him.

Teach your son to tell an adult immediately when breathing feels difficult. At six, he will still need adults to recognize and respond to symptoms.

One important safety detail: **a child struggling to breathe should have an adult stay with him while help is summoned**. Severe breathlessness, trouble speaking or walking because of it, or blue/gray lips warrant emergency help immediately; staff should not wait for a parent’s reply. The [CDC asthma action plan](https://www.cdc.gov/asthma/action-plan/documents/asthma-action-plan-508.pdf) identifies these as emergency signs.

If he already has breathing difficulty, follow his action plan and seek medical advice promptly. His clinician’s guidance and the school’s illness policy should guide attendance during future colds.
