Go to a doctor now if: Coughing fits that end in a whoop, gasp, going blue or vomiting, a cough lasting more than 2-3 weeks, any breathing difficulty, a young baby coughing or turning blue/pausing breathing, or exhaustion after bouts - seek medical care urgently (a baby who goes blue is an EMERGENCY).
Food-first comfort
Supportive comfort only, alongside a doctor's assessment: warm fluids and clear soups to loosen mucus; small, frequent meals so a coughing fit doesn't bring food back up; warm water with a little honey (1y+) to soothe the throat; steam from a warm bath; keep the air smoke-free and the room comfortably moist; upright, calm rest after meals.
What to nourish
Warm soups, dal water, soft khichdi, curd, fruit and fluids in small frequent amounts; keep hydration steady between bouts.
Never
Never rely on kitchen remedies for a whooping-type or weeks-long cough - it needs a medical diagnosis. Don't give over-the-counter cough suppressants to young children, no honey under 1 year, and keep the child away from anyone with a known whooping cough infection.
Care at home
A persistent or spasmodic cough can signal something that needs proper treatment and protects other babies from spread. Home care only keeps the child comfortable and hydrated - the diagnosis and any medicine come from the doctor.
