It's normal for babies to vomit a small amount after feeding.
Call your GP immediately if your child has:
- vomited more than 3 times in the past 24 hours
- been vomiting for more than 3 days
- shown signs of dehydration
- recently returned from travelling abroad and is vomiting more than usual
- a high temperature - 38°C for babies under 3 months, or 39°C for babies over 3 months
- severe tummy pain
- bloody or green vomit
Call 999 for an ambulance immediately if your child has a headache, stiff neck, rash and is vomiting
Caring for a child who is vomiting
In most cases you can care for your child at home. You can give them liquid paracetamol if they have a high temperature or stomach pains.
Do not worry if your child doesn't want to eat. It's more important that they drink plenty of fluids, such as water or broth. Don't give them fruit juice and fizzy drinks until they're feeling better.
If your child is still breastfeeding or formula fed, continue giving them their normal feeds.
It's not safe to dilute baby formula - make up the bottles as normal and give your baby extra water or drinks in addition to their milk feeds
Vomiting can cause your child to become dehydrated. It's important that they drink plenty of fluids.
Ask your pharmacist about an oral rehydration solution. Take your child to your GP if you're worried that they're becoming dehydrated.
Signs of severe dehydration in babies and children include:
- fewer wet nappies
- drowsiness or being hard to wake
- pale or blotchy skin
- cold hands and feet
Take your child to the nearest hospital emergency department immediately if they show any signs of severe dehydration
Vomiting can be caused by common infections like gastroenteritis (infectious diarrhoea).
More serious causes include:
- infections like meningitis, pneumonia and urinary tract infections
- gastro-oesophageal reflux
- milk intolerance or food allergies
- conditions that affect the intestines, such as pyloric stenosis or intussusception
- strangulated hernia
Call 999 for an ambulance if your child has pain that gets worse quickly and spreads across their tummy
Call your GP or go to a hospital immediately if you think your child’s vomiting could be caused by something serious.

Stop vomiting from spreading
Vomiting infections are highly contagious.
Wash your and your child's hands in soap and warm water, and dry them thoroughly:
- before and after taking care of anyone who's unwell
- after cleaning up when someone has been sick or had diarrhoea
- after going to the toilet or helping your child to go
- after changing your baby's nappy
- after handling raw meat, rubbish, an animal or their poo
- before eating
- whenever your hands look dirty
You can also:
- clean surfaces well using detergent and hot water
- wash soiled bedding and clothes at a high temperature
- wash or throw away any cleaning equipment used
- never let sick people prepare food
- make sure your sick child never shares towels with others
Keep your child at home and don't send them back to crèche or school until at least 48 hours have passed since they last vomited
