Tummy Sucking Under Ribcage: A Worrying Sign of Croup in Children
9 Sep
Summary
- NHS warns of severe croup symptoms requiring immediate medical attention
- Tummy sucking under ribcage while breathing is a concerning sign
- Croup mainly affects babies and young children, causing barking cough and breathing difficulties

As of September 9th, 2025, the National Health Service (NHS) has urged parents to seek immediate medical help if they notice their child's tummy sucking under their ribcage while breathing. This could be a sign of croup, a common but potentially serious condition affecting the upper airways of babies and young children.
Croup typically begins with cold-like symptoms, such as a runny nose and cough, but can quickly escalate into a distinctive barking cough, hoarse voice, and difficulty breathing. In most cases, croup is mild and resolves within 48 hours. However, the NHS stresses that certain severe symptoms warrant a 999 call or trip to the Accident and Emergency (A&E) department.
According to the health body, croup is caused by a viral infection, often the parainfluenza virus, which narrows the child's airways and makes it harder for them to breathe. Parents are advised to seek urgent medical attention if their child exhibits signs of distress, such as the tummy sucking under the ribcage, as this could indicate a more serious case requiring immediate treatment.
The NHS recommends that if a child is diagnosed with mild croup, parents can help alleviate their symptoms by keeping them calm and hydrated. However, they should avoid putting the child in a steamy room or having them inhale steam, as this can sometimes worsen the condition.
