DATE LAST REVIEWED: 05/11/2026
When to seek further review
- Call NHS 111 or ask for an urgent GP appointment if you think your child has croup, particularly if they have not been assessed.
- Mild croup often improves within 48 hours. Get urgent advice if your child is getting worse or is not improving after assessment or treatment.
- Seek advice sooner for poor drinking, fewer wet nappies, new noisy breathing while resting, or concern about a baby under 3 months.
- Keep your child calm and check regularly, including at night. Do not use steam or a steamy room.
- Do not wait for the suggested review time if symptoms become worse, new symptoms appear, or you are worried.
- Contact your GP when the surgery is open. If it is closed, you cannot get the help you need, or you are unsure what to do, call NHS 111. You can call even if you are not sure whether the symptoms are serious.

How to spot sepsis
Sepsis is a life-threatening reaction to an infection. It can get worse quickly. If someone is seriously unwell and may have sepsis, call 999 or go to your nearest Emergency Department. Do not wait for every sign, a high temperature or a rash.
An unwell child under 5 who has not had a pee or wet nappy for 12 hours needs emergency assessment. If you are unsure and there are no emergency signs, call NHS 111 for advice.
