Flu in Children: Symptoms, Treatment and Trusted Guidance. Flu season can be a stressful time for any parent, especially when young children start showing signs of illness. Unlike a common cold, influenza can hit harder and faster, and the uncertainty many parents feel is completely understandable. The good news is that with the right information and professional support, you can recognise warning signs early, take safe steps at home, and know when it’s time to seek help. At Hollowood Chemists , we understand how important children’s health is, and this guide explains flu in children in straightforward, relatable terms. What Is Flu and How It Affects Children Influenza, commonly called the flu, is a viral infection that affects the nose, throat and lungs. It spreads easily, especially in close-contact settings like schools and nurseries. Children’s immune systems are still developing, so they can catch flu more often than adults and sometimes feel symptoms more strongly. Flu is different from a cold. While both are respiratory illnesses, flu comes on more suddenly and often with more severe symptoms. Knowing the difference helps you respond quickly and appropriately. Common Flu Symptoms in Children Symptoms of flu in kids usually develop 1–3 days after exposure. They may include: High temperature (fever) – often above 38°C Chills and shivering Headache or muscle aches Runny or blocked nose Cough – typically dry at first Sore throat or loss of appetite Fatigue and irritability Vomiting or diarrhoea (more common in younger children) Every child’s response can differ. Some may feel very tired and quiet, while others may complain more about aches or tummy troubles. If your child suddenly seems “not themselves” or unusually lethargic, flu could be the cause. When to Be More Alert Most children with flu get better in about a week with rest and simple care. However, certain signs suggest that professional help should be sought, including: Difficulty breathing or rapid breathing Bluish lips or face Persistent high fever not improved with usual measures Dehydration signs (dry mouth, fewer wet nappies) Very drowsy, difficult to wake, or unusual behaviour Severe or continuous vomiting In such cases, contact your GP, NHS 111, or local urgent care without delay. These symptoms could indicate complications like chest infection or dehydration. First-Line Support You Can Give at Home When your child has typical flu symptoms, there are effective steps you can take straight away to ease discomfort: 1. Keep Them Rested and Hydrated Rest helps the body recover. Offer plenty of fluids like water, diluted juice or breast/formula milk for younger infants. 2. Manage the Fever Safely If your child has a high temperature and seems uncomfortable, a pharmacist can advise on appropriate doses of children’s paracetamol or ibuprofen (based on age and weight). Always follow label instructions or professional advice. 3. Ease Congestion A cool-mist humidifier in the room can help with breathing. Saline nose drops and gentle suction for babies may offer relief. 4. Encourage Light, Regular Eating If they feel like eating, small meals or snacks are fine. Don’t force food if they’re not interested — hydration is more important. How Pharmacists Can Help You If you’re unsure about symptoms or what to give at home, qualified pharmacists at Hollowood Chemists are a great first port of call. They can: Explain symptom management clearly Suggest appropriate over-the-counter medications Check medicines for interactions with existing treatments Advise when it’s necessary to see a GP or urgent care team Pharmacists provide local, easy-to-access support without an appointment. This is particularly helpful when you don’t want to wait for a GP slot or when symptoms are mild yet concerning. The Role of Flu Vaccination in Children One of the most effective ways to reduce the risk and severity of flu vaccination UK . Many children in the UK are eligible for the annual flu vaccine on the NHS, especially those with long-term health conditions or under certain age thresholds. The flu vaccine helps prime the immune system before the virus becomes widespread. It doesn’t guarantee complete protection, but it significantly reduces the chance of serious illness and complications. Speak to a pharmacist or GP about flu vaccination schedules and eligibility. When is Fever a Serious Concern? A fever is a common response to flu, but it should always be watched carefully, especially in young children: Babies under 3 months with a temperature of 38°C or more should be assessed by a clinician promptly. If your child seems unusually drowsy, irritable or non-responsive even after fever management, seek healthcare advice. Repeated or prolonged high temperatures that don’t improve with recommended care may need a professional assessment. Routine fever in the context of known flu can be expected, but always trust your instincts — if something feels off, it’s worth checking. Useful Practical Strategies for Parents Wash hands regularly — flu spreads easily by touch. Teach older children to cover coughs and sneezes. Keep tissues handy and dispose of them safely. Avoid crowded places when flu is circulating widely. Encourage daily hydration. These habits support recovery and reduce the spread of infection within your household. Key Takeaways for Families Flu in children can be worrying, but early recognition and good supportive care go a long way. Know the typical symptoms, keep an eye on hydration and fever, and don’t hesitate to reach out to professionals when needed.
