Caring for your child with gastroenteritis
Sections in this document
What is it?
Gastroenteritis is an upset tummy that can cause diarrhoea and/or vomiting. It is caused by viruses, is often mild and can usually be managed at home.
- Your child may first have tummy ache and fever
- Most children with diarrhoea and vomiting get better very quickly, but some children can get worse.
- Diarrhoea usually lasts five to seven days but may continue for up to two weeks.
- Vomiting usually does not last for more than three to four days.
Caring for your child at home
Reducing fever and pain relief for tummy aches
- Liquid paracetamol and ibuprofen can be given according the instructions on the bottle (Ibuprofen is not recommended if your child has asthma unless you have discussed with the doctor)
Keep a record
- It is useful to keep a record of the number of drinks and
- the number of wees/ wet nappies that your child/baby has had each day. The Children’s Nurses (CCN) will ask you about this when they call.
It is very important to follow the advice below to prevent dehydration in your baby/child;
One of the main risks of gastroenteritis in children, especially babies, is that they may become dehydrated
- It is important to replace fluid your child will be losing due to vomiting and/or diarrhoea.
- It is OK if they do not want to eat. Drinks are most important, and most will start eating when they feel better.
- Continue to breast/bottle feed your baby.
- For a child under one, give small sips every few minutes (using a teaspoon or a plastic syringe and aim fluids into side of mouth to ease swallowing) Your CCN/Doctor will advise you how much and how often
- For all children, give drinks little and often e.g. every 10 mins (or as advised by the CCN/Doctor). If they are thirsty and take too much at a time, it may cause them to vomit.
- For older children, try using ice lollies or encourage drinking through a straw.
- Unwell children will often refuse fluids, but can be persuaded if you persevere
- Oral rehydration solution such as Diaorlyte or Electrolade should not be used in infants under three months without agreement from the doctor
Type of fluids
- Good fluids Oral rehydration sachets, water, squash (not sugar free), milk
- Bad Fluids Juice, fizzy drinks which make diarrhoea worse
