Digestive issues are common in infants and toddlers. If your baby is experiencing possets after every feed, here is what you need to know.
The short answer
Posseting (also called "spitting up") is when small amounts of milk effortlessly flow back up after feeding. It's incredibly common in healthy babies because the valve at the top of the stomach is still developing. Most babies posset occasionally or even after every feed, and it's completely harmless as long as baby is gaining weight well and seems comfortable.
Key takeaways
- Posseting (also called "spitting up") is when small amounts of milk effortlessly flow back up after feeding. It's incredibly common in healthy babies because the valve at the top of the stomach is still developing. Most babies posset occasionally or even after every feed, and it's completely harmless as long as baby is gaining weight well and seems comfortable.
- Usually normal when: Small amounts of milk dribbling or flowing out after feeds
- Call your doctor if: Posseting becomes forceful, projectile vomiting
- Varies by age — see the age-by-age breakdown below
“The biggest concern with vomiting is dehydration. Young children can become dehydrated quickly, so it's important to replace fluids. Offer small amounts of an oral rehydration solution frequently.”
This is one of the most common questions parents ask. Searching for answers means you care.
What Parents Should Know
According to American Academy of Pediatrics, La Leche League International, Mayo Clinic guidelines, posseting (also called "spitting up") is when small amounts of milk effortlessly flow back up after feeding. It's incredibly common in healthy babies because the valve at the top of the stomach is still developing. Most babies posset occasionally or even after every feed, and it's completely harmless as long as baby is gaining weight well and seems comfortable. At 0-3 months, posseting is very common in newborns and young babies. The lower esophageal sphincter (the valve between the esophagus and stomach) is immature, and baby's stomach is small and positioned horizontally. Small amounts of milk easily flow back up, especially if baby has eaten a lot, swallowed air, or is laid down too quickly after feeding. You might notice milk dribbling from baby's mouth even an hour after feeding - this is normal. It is generally considered normal when small amounts of milk dribbling or flowing out after feeds. However, you should contact your pediatrician promptly if posseting becomes forceful, projectile vomiting.
Normal vs. Concerning
By Age
What to expect by age
0-3 months
Posseting is very common in newborns and young babies. The lower esophageal sphincter (the valve between the esophagus and stomach) is immature, and baby's stomach is small and positioned horizontally. Small amounts of milk easily flow back up, especially if baby has eaten a lot, swallowed air, or is laid down too quickly after feeding. You might notice milk dribbling from baby's mouth even an hour after feeding - this is normal.
3-6 months
Posseting often continues or even peaks around 4 months. This doesn't mean something is wrong - it's just part of normal development. Some babies posset more during or after tummy time, when bounced or moved around, or when they're laughing or babbling. The amount may look like a lot but is usually just a tablespoon or two. As long as baby is gaining weight and seems happy, frequent posseting is not a concern.
6-12 months
Posseting typically decreases significantly as baby sits upright more, the esophageal valve matures, and baby starts solids. Some babies continue to posset occasionally, especially if they overeat or are very active after a feed. If your baby is still posseting frequently at this age but is growing well and happy, it's usually fine. If it seems to be getting worse or baby seems uncomfortable, mention it to your pediatrician.
12+ months
Most toddlers have outgrown frequent posseting by this age. Occasional spit-up might still happen if they eat too much, drink while lying down, or are very active right after eating. If your toddler suddenly starts posseting frequently after months without it, consider recent diet changes or illness.
What to Tell Your Pediatrician
- Describe when you first noticed possets after every feed and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if posseting seems excessive (soaking multiple bibs per day) but baby is growing well.
- Mention if baby seems to be posseting more than before.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Small amounts of milk dribbling or flowing out after feeds
- Baby seems completely unbothered and continues to feed eagerly
- Posseting that happens shortly after feeding or even an hour later
- Baby is gaining weight according to growth curve
- At least 6 wet diapers per day
- Posseting seems excessive (soaking multiple bibs per day) but baby is growing well
- Baby seems to be posseting more than before
- You're worried about the frequency or amount
- Baby occasionally seems uncomfortable but it's not a consistent pattern
- Posseting becomes forceful, projectile vomiting
- Baby isn't gaining weight or is losing weight

- Posset is green (bile-colored), yellow, or contains blood
- Baby has fewer than 6 wet diapers in 24 hours

What You Can Do at Home
- Keep track of when you notice possets after every feed — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that small amounts of milk dribbling or flowing out after feeds — this is generally within the range of normal.
- At 0-3 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Keep your baby upright for 20-30 minutes after feeding. Note any patterns between feeds and symptoms.
- While monitoring at home, seek immediate care if posseting becomes forceful, projectile vomiting.

Related Digestive Concerns
My Baby's Belly Looks Swollen
A rounded, slightly protruding belly is completely normal in babies and toddlers due to immature abdominal muscles and their proportionally larger organs. However, if the belly becomes suddenly swollen, feels hard and tight, or is accompanied by pain, vomiting, or changes in bowel movements, it needs medical evaluation as it could signal gas buildup, constipation, or rarely, something more serious.
My Baby Has an Anal Fissure (Blood When Pooping)
A small streak of bright red blood on the surface of your baby's stool or on the diaper is most commonly caused by an anal fissure, which is a tiny tear in the skin around the anus from passing hard stool. Anal fissures are very common in babies and toddlers and usually heal on their own with simple measures like keeping stools soft. While this is rarely serious, any blood in your baby's stool should be mentioned to your pediatrician.
Can Antibiotics Damage My Baby's Gut?
Antibiotics can temporarily disrupt your baby's gut microbiome, which may cause loose stools, fussiness, or diaper rash during and shortly after treatment. However, when antibiotics are medically necessary, the benefits of treating the infection far outweigh the temporary gut disruption. Most babies' microbiomes recover within weeks to months, especially with breastfeeding and a gradual return to normal feeding patterns.
Tummy Massage for Baby Gas
Gentle abdominal massage can help relieve gas and discomfort in babies by encouraging gas to move through the intestines. The technique involves gentle clockwise circular motions on the belly (following the direction of the digestive tract), the "I Love U" stroke pattern, and gentle knee-to-tummy movements. Massage also provides comforting touch that can soothe a fussy baby.
Silent Reflux in Baby
Silent reflux occurs when stomach acid rises into the esophagus and throat but is swallowed back down rather than spit up. Babies with silent reflux may be fussy during or after feeds, arch their back, have hoarse crying, or refuse to eat, but without visible spitting up. It can be harder to diagnose than typical reflux because there is no obvious spit-up.
Bicycle Legs Technique for Gas
Bicycle legs is a simple, effective technique for helping babies pass trapped gas. Gently moving your baby's legs in a cycling motion pushes against the abdomen and helps gas move through the intestines. Combined with gentle belly massage and tummy time, it is one of the best non-medical approaches to gas relief in infants.
