My baby is vomiting
Most babies bring up small amounts of milk from time to time, especially when they burp. This is called posseting and is usually nothing to worry about. You’ll know your baby is vomiting instead of posseting because a lot more will come out.
Vomiting is also very common (it happens in up to half of all babies) and usually gets better with time. Even if it seems like your baby is vomiting a lot, most babies still grow normally and don’t seem too upset by it.
As long as your baby is healthy and gaining weight, there’s usually no need to worry or get extra help.
Please see Red-Amber-Green tables for advice on when and where to seek care for your child.
When should you worry?
If your child has any of the following:
- Has dark green or blood stained vomit
- Breathing very fast, too breathless to talk, eat or drink
- Working hard to breathe, drawing in of the muscles below the ribs, or noisy breathing (grunting)
- Breathing that stops or pauses
- Is pale, blue, mottled or feels unusually cold to touch
- Difficult to wake up or very sleepy
- Weak, high-pitched cry or can’t be settled
- Has a fit (seizure)
- Has a rash that does not disappear with pressure (the glass test)
- Has a temperature more than 38°C or under 36°C (unless fever in the 48 hours following vaccinations and no other red or amber features
You need urgent help.
Go to the nearest Hospital Emergency (A&E) Department or phone 999-consider using ‘What 3 words’ to best describe location to ambulance service
If your child has any of the following:
- Vomits forcefully (shoots across the cot or the room)

Conditions that can cause a baby to vomit:
It is normal for babies to have some reflux because the muscle at the end of their food pipe, which keeps food in their stomach, is still developing. Reflux might make your baby bring up milk after feeding and can also cause hiccups. As long as your baby is growing well and doesn’t seem very upset, there’s no need to worry.
However, more severe reflux can make your baby cry and vomit, especially after feeding. This more serious kind of reflux is called gastro-oesophageal reflux disease (GORD). It happens when your baby’s tummy is full, and food and stomach acid come back up the food pipe, causing pain and discomfort.
Do
- ask a health visitor for advice and support
- get advice about your baby's breastfeeding position or how to bottle feed your baby
- hold your baby upright during feeding and for as long as possible after feeding
- burp your baby regularly during feeds
- give formula-fed babies smaller feeds more often
- make sure your baby sleeps flat on their back (they should not sleep on their side or front)
Don’t
- do not change your diet if you're breastfeeding
- do not raise the head of their cot or Moses basket
If you’ve tried the suggestions above and your baby’s reflux hasn’t improved, you should contact your GP surgery. They will check your baby’s symptoms, ask about the formula you’re using (if your baby isn’t exclusively breastfed), and may prescribe medication.
Cow's milk proteins are found in many types of formula milk. They'll also make their way into your breastmilk if you eat or drink milk or other dairy products, such as cheese and yoghurt.
If your baby has a cow's milk allergy, they may vomit after feeding. It can be difficult to tell the difference between this and reflux. But if your baby has problems with cow's milk, they may also have:
- eczema
- colic
- diarrhoea or constipation
- trouble putting on enough weight
- history of allergies in your close family
If you're worried that your baby has problems with cow's milk, there are steps you can take. If you breastfeed your baby, you could try cutting cow's milk from your diet for 2 weeks. If your baby is formula-fed, trying a hypoallergenic formula may help.
Talk to your doctor before trying these, though. They will check your baby's symptoms first, so they can be sure of what's causing them.

- This is a rare condition that can cause your baby to vomit forcefully within half an hour of feeding.
- Pyloric stenosis is most likely to begin when your baby is about six weeks old, but could show up at any time before they reach four months of age. It can sometimes run in families, and boys are about four times more likely to get it than girls.
- It happens because the muscle controlling the valve leading from the stomach into the intestines has thickened, stopping enough food and milk to get through, so it stays in the stomach and then comes back up. The problem is easily corrected with minor surgery.
- If your baby's vomiting begins suddenly, or if they also have diarrhoea, they may have a tummy bug (gastroenteritis). Gastroenteritis is usually caused by a viral infection and needs no specific treatment. An attack of vomiting will generally subside six hours to 24 hours after it starts.
- Do not stop giving your baby milk. If you are breastfeeding, continue doing so. If your child is on formula, do not dilute it.
- Babies under 6 months of age are at more risk of becoming dehydrated than older children, which is why it is important to make ensure that they are drinking enough. Give your baby oral rehydration fluids in between feeds or after each watery stool. Your pharmacist will be able to advise you about which solution is best for your baby. Little and often tends to work best – in hospital, babies are given 1 or 2 tablespoons (5-10 mls) of fluid to drink every 5-10 minutes. You can try using a syringe to give fluids to your child.
Your baby may be vomiting because they have an infection. This is usually associated with a temperature above 38°C / 100.4°F. Although the most likely cause is a viral infection, other causes include urinary tract infections or very occasionally a more serious illness such as meningitis or sepsis. Signs of a serious infection include:
- becomes pale and floppy going blue around the lips
- is fretful or excessively miserable when touched
- becomes difficult to rouse
- is finding it hard to breathe
- develops a rash that does not disappear with pressure (the Glass Test)
Your child needs urgent help if any of these features are present - go to the nearest hospital emergency (A&E) department or phone 999.
What should you do?
If you are breastfeeding, seek advice from a breastfeeding specialist, either a specially trained health visitor or a breastfeeding counsellor. It is possible that your baby is not latching on properly. Click here for more information.
If you are bottle feeding, ensure your baby is in the right position (sitting almost upright) and that you use the recommended amount of powder (it is quite easy to use too much if you have changed product, or using a different scoop than the one provided in the tin).
It is also quite easy to give your baby too much milk when you are bottle feeding.Their stomach is only small and most babies need little and often: 6-7 feeds per day is the norm, including at night (click here for more information). Your health visitor can help review how much milk you baby should need and the timing of the feeds.
However, if after 2 weeks you are still concerned, seek advice from your health visitor or GP.

School nurses care for children and young people, aged 5-19, and their families, to ensure their health needs are supported within their school and community. They work closely with education staff and other agencies to support parents, carers and the children and young people, with physical and/or emotional health needs.
Contacting the School Nurse
Primary and secondary schools have an allocated school nurse – telephone your child’s school to ask for the contact details of your named school nurse.
There is also a specialist nurse who works with families who choose to educate their children at home.
Sound Advice
Before your child starts school your health visitor will meet with the school nursing team to transfer their care to the school nursing service. The school nursing team consists of a school nursing lead, specialist public health practitioners and school health staff nurses.
They all have a role in preventing disease and promoting health and wellbeing, by:-
- encouraging healthier lifestyles
- offering immunisations
- giving information, advice and support to children, young people and their families
- supporting children with complex health needs
Each member of the team has links with many other professionals who also work with children including community paediatricians, child and adolescent mental health teams, health visitors and speech and language therapists. The school health nursing service also forms part of the multi-agency services for children, young people and families where there are child protection or safeguarding issues.
