Spit-up is one of the most normal things babies do. About half of healthy babies spit up regularly in the first months, because the muscle at the top of the stomach is still immature. As long as your baby is gaining weight, feeding well and seems comfortable, spit-up is usually just laundry — and it typically improves by 6–12 months.
Key takeaways
- “Happy spitters” who grow well don’t usually need treatment.
- Burp during and after feeds, and keep your baby upright for 20–30 minutes afterwards.
- Smaller, more frequent feeds and paced bottle feeding reduce spit-up.
- Back sleeping remains the rule, even for babies with reflux.
- Forceful, green or bloody vomiting, poor weight gain or dehydration need urgent attention.
Spit-up vs vomiting
| Spit-up (usually normal) | Vomiting (call your doctor if frequent) |
|---|---|
| Effortless dribble or small gush | Forceful, shoots out |
| Often right after a feed or burp | Can happen any time |
| Baby seems content | Baby is distressed, unwell or lethargic |
| Milky, curdled | Green (bile) or bloody needs urgent care |
Three burping positions
- Over the shoulder: hold your baby upright against your chest, chin on your shoulder, and pat or rub their back.
- Sitting on your lap: support their chest and chin with one hand (fingers on the jaw, not the throat) and pat with the other.
- Face-down on your lap: lay your baby across your knees with their head slightly higher than their tummy, and rub gently.
Burp halfway through a bottle and at the end, or when switching breasts. If nothing comes up after a minute or two, carry on — not every feed produces a burp.
Ways to reduce spit-up
- Smaller, more frequent feeds rather than large ones.
- Paced bottle feeding with a slow-flow nipple to cut down on gulping air.
- Keep your baby upright for 20–30 minutes after feeds; avoid bouncing and car rides straight after.
- Loosen tight waistbands and diapers.
- Calm feeds: feed before your baby is frantic, in a quiet place.
Reflux disease and allergy
When spit-up comes with poor weight gain, feeding refusal, persistent arching and crying, breathing problems or blood in stool, it may be gastroesophageal reflux disease (GERD) or cow’s milk protein allergy. These need a pediatrician’s assessment — don’t switch formulas or start medicines on your own.
- vomits forcefully or repeatedly, especially a baby under 3 months (projectile vomiting can signal pyloric stenosis);
- vomits green or yellow-green fluid, or blood;
- has fewer wet diapers, a sunken soft spot, or seems very sleepy;
- isn’t gaining weight, or has trouble breathing or choking episodes.
Sleep and positioning
Keep putting your baby to sleep on their back on a flat surface. Wedges, inclined sleepers and positioners aren’t safe and haven’t been shown to reduce reflux. Supervised tummy time while awake is great — just wait a little after feeds.
Frequently asked questions
My baby spits up a lot — are they getting enough?
It often looks like more than it is. Steady weight gain and plenty of wet diapers mean they’re getting enough.
Do anti-colic bottles help spit-up?
They may help some babies who swallow a lot of air. Paced feeding and smaller volumes usually matter more.
Should I re-feed after spit-up?
If your baby seems hungry, you can offer a little more. If they’re content, wait until the next feed.
