Most babies vomit small amounts from time to time and bring up some milk when they burp. This is normal and usually nothing to worry about.
Posseting (spitting up) happens in small babies because the muscle at the top of their stomach is very soft and cannot hold the feed in.
How to reduce vomiting
Keep your baby upright for 30 minutes after a feed. Avoid putting your baby on your shoulder in a way that may squeeze their stomach.
If your baby is not too anxious to feed, try changing their nappy beforehand. Lifting your baby's legs immediately after a feed may cause them to spit up.
If you are bottle-feeding and having problems with vomiting, try using a smaller teat. Larger teats have a fast flow and can stimulate your baby’s gag reflex.
Do not force your baby to finish feeds. Wind and burp your baby often. Wait for at least 30 minutes to practice tummy time or play time.
Some babies bring up more milk than others after a feed. It can be upsetting when this happens and you may be worried that something is wrong. As long as your baby is happy and gaining weight there is usually no need to worry.
Urgent advice: Talk to your public health nurse or GP if:
- your baby seems to be in pain
- the vomiting is forceful
- you are concerned about your baby

After your baby vomits
Many babies are happy and comfortable even after vomiting or spitting up. They do not need to be fed again until they show signs that they are hungry.
