Question

My child's cough has lasted two weeks—what are the signs of walking pneumonia? Real household: caregiver juggling school week and one elder or sibling nearby. Schedule: Tue after-school 16:30; pediatrician Thu. Kitchen/home right now: cough diary, humidifier, honey (kid is 7). Already tried: waited it out thinking it was a cold. Please answer as a practical family-care guide: what to do next tonight/today, what to avoid, and a clear decision tree. Constraints: respect «No diagnosis, no medication changes»; no dosing kids/pets/elders yourself; no mystery powders or buying prescription meds online; keep steps screenshot-friendly under ~25 minutes where cooking/care applies. Structure your help as (1) what I already tried vs better alternatives, (2) constraints/avoid list, (3) red flags—when to stop DIY and get clinical/urgent help. Keep the voice concrete and kind for a tired caregiver; stay inside kitchen/home-care/communication levers only. Name what success looks like in 24 hours without promising cures. Avoid brand shopping lists; focus on routines, food already at home, and communication scripts caregivers can screenshot.

Answer

I'll work through this step by step. Let me first check the family profile and open the relevant cards for a child with a 2-week cough.

I have the cards. This is a B-level case — a 2-week cough in a 7-year-old needs clinician review (Thursday appointment is appropriate), but there's a clear red-flag tree for when to escalate sooner. Let me draft the answer.

The validator returned PASS. The WARNs are about historical box files from prior turns — they're hints only and not blocking. I'll ship the draft as-is.

7-year-old, cough for two weeks — what to watch, what to bring Thursday

Boundary (the paediatrician's lane). This note is family-side observation and prep, not a diagnosis. "Walking pneumonia" (Mycoplasma pneumoniae is one of the usual causes, but only a clinician with the exam and, sometimes, a chest x-ray or a swab can name it) can only be named by the clinician. I don't diagnose and I don't pick a medicine, a dose, or a course. Thursday's appointment is the official door for this cough.

The honest read on where you are right now: two weeks is on the edge — most short coughs in children are viral and settle in 1–3 weeks, but a cough that has not improved by week 2 in a school-age child is exactly when the paediatrician's office wants to see the child, not later. You are not late, and you are not panicking too early. The job this week is to keep watching with structure so that, if anything changes, you catch it on Tuesday or Wednesday — not at 02:00 Thursday.

1. What you already tried → what to add this week

You already have / tried	What that's missing	This week, in order
"Waited it out, thought it was a cold"	A short viral cough usually improves by day 7–10 and is mostly gone by week 3. A cough that holds steady or worsens at the two-week mark is no longer the "wait it out" picture — it's the "eyes on it, with a clinician booked" picture	You already booked Thursday. Good. Between now and then, the cough diary is your main instrument — not stronger medicine
Cough diary	A diary is only useful if the columns are simple enough to fill at 22:00 when you're tired. The minimum useful columns: date / time block (morning, afternoon, evening, night) / cough type (dry vs wet) / how hard a coughing bout was (mild, medium, stopped-the-child-talking) / temperature if taken / what the child was doing when it started (running, lying down, eating, just woke up)	Use one page per day. Don't analyse it. Bring the whole stack to Thursday. The paediatrician reads patterns in 30 seconds that take you 30 minutes to notice
Humidifier	A cool-mist humidifier in the bedroom is fine and helps some children sleep with a dry cough. A warm-mist humidifier is a scald risk around a curious 7-year-old — check the model	Keep the humidifier on cool-mist only, clean it every 2–3 days (a dirty one grows mould and makes coughs worse), and put it where the child can't reach the cord or tip it over
Honey	Honey for cough is fine for a child over 1 year old — your 7-year-old is well past the infant botulism risk. The cough source finds only modest evidence for honey as a cough soother, and it's not a treatment. Use it as a small spoonful before bed if the child wants it; not as medicine	One level teaspoon at bedtime if the cough is interrupting sleep. Don't give honey to chase a cough down during the day — it doesn't work that way
"It's probably walking pneumonia"	Walking pneumonia is one of several things that fit a 2-week cough in a 7-year-old. Others: post-viral cough (most common — the original virus is gone but the airways are still twitchy), pertussis/whooping cough (worsening cough with vomiting after coughing fits, especially if immunisation is not up to date), an inhaled object (if there was a choking episode weeks ago that was brushed off), asthma (night cough, cough with running), early typical pneumonia, or just a slower-to-clear virus. The paediatrician's job on Thursday is to tell these apart	Don't try to pick one yourself before the visit. The diary helps them pick; your guessing doesn't. If walking pneumonia is what they settle on, the antibiotic that works for it is different from the one for typical pneumonia — that's exactly why it has to be them choosing, not you

What to bring to Thursday's appointment

The cough diary — every day since the cough started, even the rough early days
Any temperature readings with the time of day
A one-line list of other symptoms you noticed but didn't write down: sore throat, ear tugging, runny nose, rash, vomiting after cough, fewer wet nappies / less pee, more tired than usual
Any choking episode in the last 2 months — even one the child barely mentioned
Immunisation record if you have it (pertussis booster timing matters)
Any medicines you've given — name, how much, how often, how many days (even things you bought over the counter)
Three questions you want answered:

- "What should bring us back before Thursday follow-up?"
- "Over what time should this cough be getting better, and what's the next checkpoint?"
- "Could this be walking pneumonia / pertussis / something we should test for?"

2. What not to do (avoid list)

Don't give over-the-counter cough syrup or cough-and-cold medicine to a 7-year-old "to help". The paediatric source finds no good evidence they help children and names risks. A cough is the airway clearing itself — suppressing it doesn't treat the cause. If the cough is waking the child every night, the right conversation is with the paediatrician on Thursday, not the pharmacy tonight
Don't give aspirin for fever or discomfort in a child — it's linked to Reye syndrome in kids with viral infections
Don't start leftover antibiotics "just in case it's bacterial." Leftover antibiotics are usually the wrong drug, the wrong dose, and the wrong length — and they muddy what the paediatrician sees on Thursday
Don't alternate two fever medicines "to keep the fever down." One medicine, by the label, is the rule. If fever is the worry, the cough is the worry, and breathing is the worry — bring the child in, don't escalate doses at home
Don't smoke or vape in the house (or let anyone else) while the cough is going on. Smoke is the single biggest avoidable irritant on a healing airway
Don't warm-mist the room. Cool-mist only. Warm-mist humidifiers are a scald and a burn risk around a child
Don't restrict the child to bed "to rest the cough." A short easy walk outside is fine if the child wants to go. Forced rest makes everyone more tired and doesn't shorten the cough
Don't send the child to school with a fever or with a cough that won't stop during class — most schools want a child home until the fever is gone for 24 hours without medicine, and a cough that interrupts the day is a reason to keep them home one more day, not a reason to push through
Don't chase the cough with multiple remedies at once (honey + OTC syrup + steam + menthol rub + vitamins). Pick one soother (the honey, or the humidifier, or a warm drink) and let the rest of the work happen on Thursday
Don't delay calling sooner than Thursday if any red flag below appears tonight or tomorrow

3. Red flags — when to stop "wait for Thursday" and get help today

> A 2-week cough in a school-age child who is otherwise well, drinking, playing, peeing normally, and not working hard to breathe is a B (clinician review, Thursday is appropriate). The list below is what moves it up to C (contact local emergency services now) or to call sooner than Thursday.

Call local emergency services now — C

Working hard to breathe: sucking in below the ribs or at the neck, grunting, nostrils flaring, can't speak in full sentences because they're out of breath, lips or fingertips turning blue or grey, or they've gone quiet and drowsy after a bout of struggling
Can't drink or won't swallow for several hours, or is too out of breath to take a sip
A coughing fit that turns the child blue, or a fit that ends in vomiting and the child can't catch their breath afterwards
A barking cough with a harsh noise on breathing in, or a hoarse voice with drooling and refusal to swallow — this is upper-airway, not a chest cold, and is treated as an emergency
Sudden severe chest pain that came on with the breathing trouble (a stabbing pain on breathing in)
Becomes limp, floppy, hard to wake, or is acting confused — these are "looks seriously unwell" signs regardless of the temperature
Stops breathing for a moment, or a coughing fit that the child can't seem to come out of

Call the paediatrician's office today (or your local after-hours line) — B / sooner than Thursday

Fever comes back after a few days of no fever, or new fever at the two-week mark
Breathing is faster than usual at rest, even if the child can still speak and isn't blue
Cough is now producing coloured spit (yellow / green / brown) and the child is more tired than last week
A coughing bout ends in vomiting more than once, or ends in a gasping "whoop" — this is the pertussis pattern and is worth a sooner call, especially if immunisation isn't current
Child says "my chest hurts" when they cough, or refuses to lie down because coughing is worse lying flat
Wet cough that's been there every day for >4 weeks — that's the threshold for chronic cough and a different workup
Ear tugging, severe sore throat, or a new rash — these can travel with the same viral cause and may not be "just the cough"

Tonight care — A (only after the B/C rows are excluded)

Cool-mist humidifier running in the bedroom; clean it every 2–3 days
Honey, one level teaspoon at bedtime if the child wants it (over 1 year old — your child is fine)
Warm clear drinks — water, weak warm tea with a little honey, or warm apple juice — small sips through the day, especially before bed
Let the child sleep in whichever position they choose; if they want to be propped up on an extra pillow, let them
Check on them once during the night: are they breathing comfortably, can they speak in a sentence if you wake them, are they pink, are they peeing normally in the morning?

Decision tree (one glance)

```
Cough 2 weeks in a 7-year-old
│
├── Working hard to breathe / blue / can't speak / won't drink?
│ → CALL LOCAL EMERGENCY SERVICES NOW. Don't drive; follow the dispatcher.
│
├── Barking cough + drooling + hoarse voice?
│ → CALL LOCAL EMERGENCY SERVICES NOW.
│
├── Cough is getting worse at week 2 / fever returned / vomiting after cough / new chest pain?
│ → CALL PAEDIATRICIAN TODAY (or after-hours line). Don't wait for Thursday.
│
└── Otherwise well: drinking, peeing, playing, not working hard to breathe
→ Keep the Thursday appointment. Use the diary. Cool-mist + honey at night.
Watch for any of the above appearing — that's when Thursday moves up.
```

What "good" looks like in the next 24 hours (without promising a cure)

The child sleeps more comfortably tonight because the room air is moist and there's a small honey-and-warm-drink routine before bed
You have one page of the cough diary filled in by tomorrow morning — even a rough one
You have the Thursday list of medicines-given, choking-episode notes, and three questions ready in your phone, not in your head
You have not started any new medicine, antibiotic, OTC syrup, or "natural" remedy tonight
You know which red flag would make you pick up the phone tonight or tomorrow morning instead of waiting for Thursday
By Thursday you are answering the paediatrician's first three questions in 30 seconds, not 30 minutes

The cough may still be there on Thursday. That's fine. The job of the next two days is to arrive at that appointment with eyes open, not to make the cough go away before then.
