In babies, 'spilling' or 'spitting up' stomach contents is a normal process that helps to relieve an uncomfortably full stomach. While spilling is generally not considered a concern and doesn't need medical treatment, there are a few things you can do to cope with your baby's spilling.

- Tips for being prepared for spills
- Up to 70% of health babies spill regularly with a peak around age 4 months. This is because their digestive system (gut) is not yet fully developed.
- Most children outgrow spilling between 6 and 12 months. It generally improves as your baby becomes more upright, their diet becomes more solid and their gut function matures.
- As long as your baby is healthy and growing normally, spilling should not be a cause for concern.
- A more-severe form of reflux, known as gastro-oesophageal reflux disease (GORD), is rare. Symptoms of GORD include poor weight gain, feeding difficulties, severe restlessness and, sometimes, frequent spilling.
- f you are concerned your baby may have GORD, see your doctor for diagnosis and treatment.
Reflux happens when stomach contents are released back up into the swallowing pipe (oesophagus).
- There is a ring of muscle at the top of your stomach that should close when feeding stops.
- In babies and young children this valve is underdeveloped and may not close properly. This causes food and digestive acids to leak back up from their stomach into the oesophagus.
- Sometimes, but not always, milk spills out their mouth.
- Reflux usually happens after feeding, but it can also occur when your baby cries, coughs or strains.
In some cases, reflux can be caused by something different:
- Allergic reaction – an immune response to a food ingredient, most commonly cows' milk protein.
- Reflux oesophagitis – inflammation of the oesophagus lining due to stomach acid leaking up (refluxing) from the stomach.
- Eosinophilic oesophagitis – inflammation of the oesophagus lining due to build-up of white blood cells (eosinophils). This is usually caused by allergy to cows' milk protein.
- Gut obstruction – a narrowing or blockage of the oesophagus or of the area between the small intestine and stomach (pyloric stenosis).
As long as your baby is healthy and growing normally, reflux should not be a cause for concern. It is different to vomiting because reflux or spilling is effortless, while vomiting is forceful. Read more about vomiting in children.
Contact your family doctor if your baby:
- brings up a large amount of milk after most feeds
- spits up forcefully (projectile vomiting)
- spits up green or yellow fluid
- is fussy and unhappy between feeds
- arches their back or seems to be in pain after most feeds
- is not gaining much or any weight
- has breathing problems
- starts vomiting at age 6 months or older.
Reflux is commonly blamed for causing irritability in babies. However, it is very normal for babies to wake frequently and cry lots, especially between about 2 to 8 weeks of age. Read more about how to cope with a crying baby.
- Reflux usually begins before babies are 8 weeks old and may continue until about 4 months of age.
- Most babies get better before they are 12 months old, as their digestive system matures, they become more upright and their diet becomes more solid.
- A few children still experience reflux after 12 months old.
- If your toddler or older child has reflux and it is causing them distress, take them to see your family doctor.
Reflux does not usually need any special tests or treatment. However, while your baby’s digestive system is still developing, there some things you can do to help with it.

If you have tried the suggestions above and nothing seems to be working, talk to your lead maternity carer, local well child provider or doctor. They may suggest other strategies.
They may also discuss the use of feed thickeners and other medicines to reduce the spilling, particularly if your baby also has significant pain or growth problems.
- Feed thickener is added to baby formula with the idea that it makes the formula heavier and less likely to rise back up the oesophagus.
- Medicine such as Infant Gaviscon works as an antacid (to neutralise stomach acids) and a thickener.
- It can be given to breast-fed infants in place of thickened formula.
- Medicine such as omeprazole may be considered for the small number of babies that have GORD.
Looking after a baby who's constantly spilling can be frustrating. Being prepared can help you manage the situation.
- Place a towel or flannel over your shoulder when you are carrying your baby upright.
- Dress your baby in vests and sleepsuits, as they're easy to wash.
- Pick a special sofa or chair for when you're sitting with your baby, and cover it with a throw or sheet. Have a spare cover so you can wash one while using another.
- Use a washable cover on your baby's car seat or pushchair. Again, have a spare so you can wash one and use one.
- Pack extra sets of clothes for you and your baby. Also carry a a bag for soiled clothing.
If you are coping with a baby who cries constantly and won't sleep, it's easy to feel overcome and exhausted. It can be helpful to get support for yourself and talk to others about managing your baby’s reflux from day to day.
