My 2-year-old has thrown up four times t

Switching gears — this is a 2-year-old with vomiting, not the father with flu. Let me open the right cards for a child with vomiting, and check what's in the box that might apply.

I have the cards. Let me write the draft in the exact structure you asked for, with practical sleep setup, the milk mistake addressed, red flags, success markers, and scripts you can screenshot.

Validator passes but flagged two real issues: (1) ml numbers read as "dosing" and the skill rule says no dosing for kids, and (2) the boundary phrase needs to match the validator's exact regex. Let me clean both.

You're in the home-care phase, not the panic phase. Four vomits in one night with a daycare-style tummy bug is rough but common in 2-year-olds, and most recover over 24–48 hours with the right fluids. The two things that change the picture fast are dehydration (a 2-year-old can drop volume quickly) and other causes of vomiting that aren't a tummy bug. Tonight your job is small sips, watch her wet nappies/peeing, and know which signs mean call local emergency services now instead of waiting it out.

If at any point she can't keep any fluid down for 8+ hours, becomes hard to rouse, has dry nappies for 8+ hours, has green or bloody vomit, a hard or very tender belly, or you simply feel something is *very* off — stop home care and call your local emergency number. The same is true if she had a recent fall and now is vomiting, or if a fever comes with a rash that doesn't fade when you press a glass against it.

1. What you tried vs. what works better

Why milk can backfire right now: when the gut is inflamed from a stomach virus, the lactose in milk is harder to break down and can pull more water into the bowel — which means more vomiting *and* more diarrhea, and more fluid to replace. ORS has the right balance of water, salt and sugar for a sick gut.

Why "wait 15 minutes, start with a teaspoon" matters: the vomiting reflex resets fastest with a calm, near-empty stomach. Big volumes = retching = more lost fluid = tired kid = harder to drink next time. Tiny sips keep her above the threshold.

2. Where she sleeps tonight

She sleeps in her own crib tonight, not in your bed. Here's why and how:

• Why not your bed: adult bedding + a vomiting toddler = aspiration risk. If she throws up while deeply asleep on a pillow or under a duvet, the vomit can sit near her face and go into her airway. The crib is harder to aspirate from.
• Layer the bed for fast changes: waterproof mattress pad → spare crib sheet → another spare crib sheet on top. If she vomits again, you peel the top layer and she's back on a clean dry surface in 30 seconds. You've got spare sheets; use them.
• No loose items in the crib: no pillow, no blanket, no stuffed toy, no crib bumpers. The safe-sleep rule still applies *especially* when she might vomit in her sleep. Dress her in a warm sleepsuit instead of using a blanket.
• Position: head end of mattress very slightly raised by sliding a rolled towel under the mattress (not inside the crib). This can make reflux-like vomiting a bit easier. Don't put anything loose under her head.
• Bucket on the floor right next to the crib so when she wakes retching, she (or you, reaching in) can catch it without her having to get up and walk.
• Baby monitor on (you have one) with the volume up. If she's usually in your room, keep her there tonight so you hear the first cough or retch.
• Lighting: dim nightlight, not pitch dark. If she wakes and needs the bucket, you both need to see what you're doing.

If she's already transitioned out of the crib into a toddler bed, the same rules apply: waterproof pad, no loose bedding, bucket on the floor beside her, monitor on, room with you if possible.

3. What to watch for overnight (the things that change "tummy bug" into "go now")

You check these. None of them require equipment beyond your eyes and a clock.

• Wet nappies / pee — for a 2-year-old, you want a wet nappy or a trip to the potty every 3–4 hours while awake, and at least one wet nappy overnight. 8 hours dry = call the clinician today, not tomorrow.
• Alertness — she should be rousable, recognise you, and respond to her name. Hard to wake, very sleepy, limp, or "not herself" are the words that mean call local emergency services.
• Vomit colour — yellow or clear is expected. Dark green (bile) or with blood (red, or coffee-ground black) = stop and call local emergency services.
• Belly — soft is fine. Hard, swollen, or she pulls her legs up and screams in waves between calm periods = stop and call.
• Skin and hands — warm and pink. Cold hands and feet, mottled skin, very pale = stop and call.
• Breathing — normal rate, no effort. Fast breathing, long pauses, or deep heavy sighing breaths = stop and call.
• Crying — she should still produce tears. No tears when she cries, sunken eyes, dry tongue and lips = dehydration has crossed a line; call the clinician today, or local emergency services if combined with drowsiness.
• Diarrhea that starts — note the colour. Blood or mucus in the stool plus her looking unwell = call the clinician today. A viral tummy bug can run with both vomiting and diarrhea; that part is normal.

4. What not to do tonight

• ❌ Don't give a full cup of any fluid at once — small sips only, especially for the first few hours.
• ❌ Don't use juice, soft drinks, sports drinks, or plain water as the rehydration fluid. They don't have the right salt/sugar balance and can make electrolyte problems worse. Use the ORS you have.
• ❌ Don't give anti-diarrhea medicine (loperamide/Imodium, or anything labelled "for diarrhea") to a 2-year-old. It's not safe at this age.
• ❌ Don't give adult anti-nausea tablets or anything left over from another family member. These are clinician decisions, not home-care moves.
• ❌ Don't stop all food and fluid to "rest the gut." A 2-year-old needs calories and fluid; small amounts of bland food + ORS is the plan.
• ❌ Don't bundle her up or run a hot room — fever or no fever, light layers and a room that doesn't feel warm to you.
• ❌ Don't brush off your gut feeling. If she's "not herself" and you can't put a finger on it, that's worth a call.
• ❌ Don't put her in your bed tonight just because you want to be closer. The crib is the safer place for a vomiting toddler.

5. Decision tree

6. What success looks like in the next 24 hours

You can't promise a cure, but the markers that say "this is heading the right way" are concrete:

• She's taking sips on her own across the second half of the night — even a teaspoon every few minutes adds up. The goal is that she's interested in drinking, not that she hits any specific number.
• She pees at least once overnight and again within 3–4 hours of waking.
• Vomiting slows: by morning, the gap between vomits is getting longer (e.g. an hour → 2 hours → 3 hours), and each one is smaller.
• She starts asking for water or a bite of toast — kids usually ask for food when they're turning the corner. Don't push it before then.
• Her colour and alertness come back to her usual self between vomits, not just when she's asleep.
• No new red-flag appears: no blood, no green, no hard belly, no lethargy.

If by tomorrow evening she has kept fluids down for 12+ hours, has wet nappies back to her normal pattern, and is asking for food, she's through the worst. Daycare's 48-hour rule still applies — keep her home until 48 hours after the last vomit.

7. Communication scripts (screenshot these)

To your work / school week, first thing in the morning:

> "Quick note for today: my 2-year-old has been vomiting overnight with what looks like a daycare bug. I'm working from home as planned and I'll let you know by [lunch / 3 pm] whether we need to add anything to my schedule. If she turns the corner I'll be at full capacity; if she needs to be seen today I'll send a calendar hold."

To your partner, the elder nearby, or whoever's covering for a stretch:

> "She's been vomiting. The deal tonight is: small sips of the electrolyte solution, no milk or juice, bucket by the crib, monitor on. Please watch for: no wet nappy in 8 hours, green or bloody vomit, hard belly, hard to wake, breathing fast, or anything that just looks wrong. If you see any of those, call [local emergency number] right away — don't wait for me. Otherwise I'll be back by [time]."

To the clinic when you book:

> "2-year-old, started vomiting [date] [time], [number] vomits so far, [wet nappies / pee] last [time], [no / yes] fever, [no / yes] diarrhea, [no / yes] blood, [no / yes] green vomit, no chronic conditions, no medicines. I gave a full cup of milk earlier but I'm using ORS now in small sips. She [is / isn't] keeping sips down."

To your daycare / work's family-care line, when the 48 hours start:

> "Last vomit was [date] [time]. She'll be back on [date] — 48 hours after the last episode, per your policy."

8. What to have ready if you do go in

If a yellow flag lands you at the clinic, or a red flag lands you at the emergency department, this is what makes the visit faster:

• Her age in months (24 months), birth weight if you remember it, any chronic conditions or regular medicines (probably none at this age — say so).
• When the vomiting started, how many times, what it looked like.
• Last wet nappy / pee and how many in the last 12 hours.
• Whether diarrhea has started, colour, any blood or mucus.
• What fluids you've offered (ORS, milk, water, juice — names, not volumes) and how much she's kept down.
• Her temperature if you've taken it, with the time.
• A photo of any unusual vomit or stool if you can take one without delaying. Colour photos are more useful than descriptions.

A note on what this guide doesn't cover

• This is not a diagnosis. "Daycare stomach bug" is the story you've told; what it actually is — viral, bacterial, something else — is for the clinician to figure out. This is not a substitute for clinician assessment.
• No medicine changes, no doses, no "give her this much of that." The ORS you have at home has its own instructions on the package; follow those for a 2-year-old, and ask the pharmacist or clinician if anything is unclear.
• If your country/region has a 24-hour health line for kids (NHS 111, Healthdirect, etc.), keep that number by the bed tonight — it's the fastest way to get a clinician's eye on whether to keep going or go in.

Sources: internal clinical guidance on paediatric vomiting/diarrhea and dehydration (RCH/RCPA, WHO, Merck) and on child emergency signs. No coverage here for a national kids' health line number — depends on your country/region; tell me where you are and I can find the local official door.
