Digestive issues are common in infants and toddlers. If your baby is experiencing i see undigested food in my baby's poop, here is what you need to know.
The short answer
Seeing undigested food in your baby's poop is completely normal, especially when they are first learning to eat solids. Babies are still developing the ability to fully chew and digest certain foods, and many common foods like corn, blueberry skins, peas, raisins, and tomato skins are naturally difficult to break down. As long as your baby is growing well and not having other digestive symptoms, this is nothing to worry about.
Key takeaways
- Seeing undigested food in your baby's poop is completely normal, especially when they are first learning to eat solids. Babies are still developing the ability to fully chew and digest certain foods, and many common foods like corn, blueberry skins, peas, raisins, and tomato skins are naturally difficult to break down.

- Usually normal when: You see recognizable pieces of corn, peas, blueberry skins, raisins, or other high-fiber foods in your baby's diaper
- Call your doctor if: Your baby has chronic diarrhea with large amounts of undigested food along with poor weight gain or weight loss, which could indicate a malabsorption condition
- 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.”

What Parents Should Know
According to AAP, Mayo Clinic, NIDDK guidelines, seeing undigested food in your baby's poop is completely normal, especially when they are first learning to eat solids. Babies are still developing the ability to fully chew and digest certain foods, and many common foods like corn, blueberry skins, peas, raisins, and tomato skins are naturally difficult to break down. As long as your baby is growing well and not having other digestive symptoms, this is nothing to worry about. At 6-9 months, when babies first start solids, their digestive system is still maturing. It is very common to see recognizable pieces of food in their diapers, especially with foods that have tough skins or fibrous structures like peas, blueberries, and beans. Babies at this age also tend to swallow food with minimal chewing since they are still developing their chewing skills. Offering well-cooked, soft foods cut into appropriate sizes helps, but some undigested food in the stool is expected and normal. It is generally considered normal when you see recognizable pieces of corn, peas, blueberry skins, raisins, or other high-fiber foods in your baby's diaper. However, you should contact your pediatrician promptly if your baby has chronic diarrhea with large amounts of undigested food along with poor weight gain or weight loss, which could indicate a malabsorption condition.
Normal vs. Concerning
By Age
What to expect by age
6-9 months
When babies first start solids, their digestive system is still maturing. It is very common to see recognizable pieces of food in their diapers, especially with foods that have tough skins or fibrous structures like peas, blueberries, and beans. Babies at this age also tend to swallow food with minimal chewing since they are still developing their chewing skills. Offering well-cooked, soft foods cut into appropriate sizes helps, but some undigested food in the stool is expected and normal.
9-12 months
As babies become more experienced eaters and develop more teeth, you may notice less undigested food in their stools, though it will still appear with certain foods. Corn, for example, has an outer shell made of cellulose that humans cannot digest at any age. Raisins, grape skins, tomato skins, and leafy greens are also commonly seen. This is a sign that your baby is eating a varied diet, not that something is wrong.
12-24 months
Toddlers eat a wider variety of foods and chew more effectively, but undigested food in the stool remains common and normal. If your toddler eats quickly or does not chew thoroughly, you may see larger pieces of food in the diaper. Encouraging slower eating and thorough chewing helps, but is a gradual learning process. Some foods will always appear in the stool because they contain insoluble fiber that the human body simply does not break down.
24-36 months
By this age, you should see less undigested food overall, but it is still normal to occasionally spot corn kernels, skins of fruits and vegetables, seeds, and nuts in the stool. If your child is consistently passing large amounts of undigested food, has foul-smelling or greasy stools, or is not gaining weight appropriately, these could be signs of a malabsorption issue and should be evaluated by your pediatrician.

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.
