Children’s health: Tummy bugs

If your child seems to be catching every bug that’s going around, it may be distressing but it’s also normal. After all, children are particularly prone to getting sick when they’re young because their bodies are still building immunity to all those germs they encounter regularly in the school playground.
As a parent, it’s natural for you to want to stop your child ever getting sick. But not only is that very difficult – perhaps even impossible – to achieve, it’s also not advisable. That’s because being exposed to a variety of bugs will make your child’s immune system stronger, which can help them resist a range of illnesses as they get older.
It’s thought most children will catch at least one or more infectious illnesses at some stage. According to the National Institute for Health and Care Excellence (NICE), children experience an average of five to eight colds – which are common causes of ear infections – every year (compared with two to three colds a year in adults) (i).

Routine vaccines are available to protect children against more serious diseases. Many important childhood vaccines are available free on the NHS, with the first ones given when a baby is just two months old (or even earlier, as pregnant women can protect their unborn baby against whopping cough by getting a vaccine, typically when they are 28 - 32 weeks pregnant).
Besides making sure your child receives their vaccinations at the right times, you may want to be aware of the signs and symptoms of common childhood infections. It’s also a good idea to arm yourself with information on what you can do to make your little one feel better when they do bring a bug home from school.

How do infections spread in children?

Bugs that cause illness – or pathogens, to give them their scientific name – can spread easily in schools and nurseries because these are places where children play in close contact with one another. If one child is infected with a tummy bug they can easily infect others if the virus is still on their hands after they’ve been to the toilet, either through direct contact or by infecting surfaces or objects that other children touch.
This is why health experts recommend that parents teach their children good hygiene practices – including keeping their hands as clean as possible – early on, especially before they start nursery, day care or school. Other helpful hygiene practices you can pass on to your child include encouraging them not to share things like cups, cutlery, towels or flannels.

When should you take your child to a doctor?


While many common childhood infections can be treated easily at home, it’s important to get professional medical advice if you’re concerned in any way about your child. Also take them to see their GP if your child doesn’t start to improve after a day or two of being looked after at home, if their symptoms are getting worse, or if any of the following apply:

  • They have pain that doesn’t get better after taking children’s paracetamol or ibuprofen.

  • They have a high temperature that doesn’t improve within five days (see our guide to Children’s health: fever or high temperature for more essential details).

  • They’re having persistent vomiting and/or diarrhoea (that is, they have vomited three or more times or have had diarrhoea six or more times in 24 hours).

  • They refuse to drink anything or can’t keep liquids down.

  • They’re producing fewer than half their usual number of wet nappies.

  • They are aged three months or younger and have a fever or aren’t feeding as well as usual.

Take them to see their doctor straight away or call for an ambulance if…

  • They are having breathing difficulties.

  • They look very pale and are hard to wake.

  • They have a rash combined with a headache, stiff neck or back pain.

  • They have a rash or spots that don’t disappear when you place the side of a clear glass against them (read our guide to Septicaemia and meningitis in children to find out more details about the danger signs to look out for).

How do I know if my child has got Gastroenteritis?

This is very common, particularly among young children, with many having more than one episode in a year (ii).Gastroenteritis causes diarrhoea and vomiting, with other symptoms including stomach cramps, aches and pains, headache and a high temperature. It’s most often caused by a virus, with rotavirus and adenovirus being the types that usually cause stomach infections in children.
Viruses that cause gastroenteritis are easily spread in schools and other places where children are in close contact with one another. However the symptoms are often mild and usually improve within a few days without any medical treatment. But if a child’s symptoms don’t improve, if they are particularly unwell or if you’re concerned in any way, take them to see their GP. If they have recently been abroad and have since become unwell with gastroenteritis symptoms, it’s also important to get professional medical advice.

How can you treat gastroenteritis at home?

  • Make sure your child gets plenty of rest.

  • Try to give them frequent sips of water or diluted fruit juice to prevent dehydration. If they aren’t able to drink or can’t keep any fluids down, ask a doctor for advice (they may, for instance, recommend giving your child rehydration drinks made from special sachets that you can buy at pharmacies). 

  • If they have a headache, other aches and pains or a high temperature, you can give them paracetamol or ibuprofen to make them feel more comfortable. 

  • Disinfect their toilet after every use, as well as other surfaces in the bathroom such as taps and door handles using hot water and detergent. Also make sure they wash their hands thoroughly after using the toilet. 

  • Keep them off school for at least 48 hours after the last time they had diarrhoea or vomiting, and make sure they aren’t in contact with any other children while they’re at home. 

  • When they are ready to eat, give them plain foods such as soup, pasta, bread or boiled rice.

Natural support for children's immunity


You may not be able to stop your child going down with a bug, but there are things you can do to support their immune system while they’re sick and to help keep their immunity strong when they’re well.
Good nutrition is important for keeping your child as healthy as possible, which means keeping their immune system healthy too. So try to make sure they get at least five portions of fruit and vegetables every day, as this means their body will be getting a good range of nutrients.
You may also want to consider giving them a multivitamin and mineral supplement – especially if they are a fussy eater. Choose a good-quality supplement designed for children that will give them all the important vitamins and minerals their immune system needs. If they don’t like swallowing tablets there are other options, such as effervescent multivitamin and mineral tablets that dissolve in water to make a pleasant-tasting drink, as well as tasty chewable multivitamin and mineral tablets (look for one that’s kind to their teeth).
Not sure what to choose? Take a look at our guide to Multivitamins for children to help you decide.
High-strength fish oils   You may also want to consider giving your child a fish oil supplement, since the omega-3 fatty acids found in oily fish such as salmon, herring, mackerel and sardines are widely thought to be helpful for children’s general health (plus they’re ideal for kids who don’t like the taste of fish). Fish oil supplements often tend to be quite large, so look for one that comes in a small capsule size that a child can swallow easily.
Elderberry   Grown on the Sambucus tree, elderberries have a long traditional use for the relief of colds and flu. Look for a good-quality, naturally sweetened elderberry liquid that your child will love to take straight off the spoon.
Vitamin C   This is an important vitamin that’s needed for many body processes. Experts also believe that not getting enough vitamin C may weaken a child’s immune system (iii). You can find vitamin C in multivitamin and mineral supplements, but it’s also available as a single supplement.
Zinc   We all need zinc for a healthy immune system, but many of us – including children – may not be getting enough of it in our diets. Foods that contain good levels of zinc include meat, shellfish, legumes, nuts, seeds, dairy foods, eggs and whole grains. If your child doesn’t eat many zinc-rich foods, a supplement may be the answer. Most good-quality multivitamin and mineral supplements will contain a decent level of zinc, but you could also try giving them zinc lozenges (these not only taste nice but you can get them with added vitamin C too).
Vitamin D   Children need to get the right amount of vitamin D for their immune systems to function normally. These days, the government recommends that all children from birth to four years old take a daily vitamin D supplement throughout the year, while those who are four years and older should take it during the autumn and winter months (though there’s a good argument for giving children of any age vitamin D supplements all year round if they don’t spend much time outdoors in the spring and summer months or if they usually wear clothes that cover up most of their skin when they’re outdoors).
Again, you can give your child the vitamin D they need in a good multivitamin supplement. Alternatively there are vitamin D supplements available – and if your child doesn’t like taking tablets, you can give them vitamin D drops.
It’s never easy for parents when their children are sick, but having common mild infections like tummy bugs is normal and it even makes their immunity stronger and healthier. Knowing the difference between a mild infection you can treat at home and something that may be more serious is essential for all parents – plus it can also be helpful to know how to soothe their symptoms when you’re looking after them. There’s lots more information on children’s and adults’ health conditions in our pharmacy health library – why not take a look around?
