Go to a doctor now if: A high-pitched or squeaky sound breathing IN (stridor) at rest, struggling to breathe, sucking-in at the ribs/neck, blue or grey lips, drooling or unable to swallow, or a child who is very distressed or floppy - call emergency help immediately.
Food-first comfort
Keep the child calm - crying makes it worse - and upright; offer sips of warm or cool fluids to soothe the throat; a calm, comfortably humid room (sitting in a steamy bathroom with the hot tap running, child never left alone) can ease a mild bout; small light meals if the child wants them. This is comfort care while you judge the breathing.
What to nourish
Warm or cool fluids, soups and soft foods in small amounts; keep hydration up between coughing spells.
Never
Never ignore noisy or laboured breathing. Don't put anything in the throat, don't use adult cough medicine, and don't leave a child alone in a steamy bathroom. Barking cough with breathing struggle is not a wait-and-see situation.
Care at home
Croup is common in little ones and mild cases settle with calm and moist air. But the airway is small, so any noisy breathing at rest or breathing struggle is a genuine emergency - trust that instinct and get help fast.
