Digestive issues are common in infants and toddlers. If your baby is experiencing baby not pooping for a week - when to worry, here is what you need to know.
The short answer
For breastfed babies over 6 weeks old, going up to 7-10 days without a bowel movement can be completely normal - breast milk is so well-digested that there is very little waste. For formula-fed babies, going more than 3-4 days without pooping is unusual and may indicate constipation. The key indicator is not frequency but consistency - if the poop is soft when it finally comes, your baby is not constipated regardless of the gap. Hard, pellet-like stools with straining indicate true constipation.

- Usually normal when: Your breastfed baby over 6 weeks goes several days without pooping but produces a large, soft stool when they finally go
- Call your doctor if: A newborn under 6 weeks who has not passed meconium within 48 hours of birth or stops pooping
- 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 AAP, NIH guidelines, for breastfed babies over 6 weeks old, going up to 7-10 days without a bowel movement can be completely normal - breast milk is so well-digested that there is very little waste. For formula-fed babies, going more than 3-4 days without pooping is unusual and may indicate constipation. The key indicator is not frequency but consistency - if the poop is soft when it finally comes, your baby is not constipated regardless of the gap. Hard, pellet-like stools with straining indicate true constipation. At 0-6 weeks, in the first 6 weeks, both breastfed and formula-fed babies should poop at least once daily - multiple times is common. Fewer than 3-4 poops per day in the first month for breastfed babies can indicate insufficient milk intake. If your newborn under 6 weeks has not pooped in 24-48 hours, contact your pediatrician, as this could be a feeding issue or, rarely, a sign of Hirschsprung disease (a condition where nerves in the colon are missing). It is generally considered normal when your breastfed baby over 6 weeks goes several days without pooping but produces a large, soft stool when they finally go. However, you should contact your pediatrician promptly if a newborn under 6 weeks who has not passed meconium within 48 hours of birth or stops pooping.
Normal vs. Concerning
By Age
What to expect by age
0-6 weeks
In the first 6 weeks, both breastfed and formula-fed babies should poop at least once daily - multiple times is common. Fewer than 3-4 poops per day in the first month for breastfed babies can indicate insufficient milk intake. If your newborn under 6 weeks has not pooped in 24-48 hours, contact your pediatrician, as this could be a feeding issue or, rarely, a sign of Hirschsprung disease (a condition where nerves in the colon are missing).
6 weeks - 6 months
After 6 weeks, breastfed babies famously develop longer gaps between bowel movements. Some poop after every feed and some poop once a week - both are normal as long as the poop is soft. Formula-fed babies typically poop daily or every other day. If your formula-fed baby goes more than 3 days, try gentle belly massage, bicycle legs, and ensure the formula is mixed correctly. Do not add anything to bottles (juice, corn syrup) without pediatrician guidance.
6-12 months
Starting solids changes poop patterns significantly. It is normal for poop to become firmer, darker, and less frequent. Constipating foods include bananas, rice cereal, and dairy. High-fiber foods (prunes, pears, peas, oatmeal) help keep things moving. Offer water with meals once solids are established. If your baby strains, has hard pellet-like stools, or has painful bowel movements, increase water and fiber-rich foods.
12-36 months
Toddler constipation is very common, especially during potty training. Withholding poop (refusing to go) can create a painful cycle - hard stool causes pain, so the child holds it more, making it harder. If your toddler is not pooping for several days and the stool is hard when it comes, your pediatrician may recommend Miralax or another osmotic laxative. Increasing fiber, water, and physical activity helps prevent constipation.
What to Tell Your Pediatrician
- Describe when you first noticed baby not pooping for a week - when to worry and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if your formula-fed baby regularly goes 4+ days without pooping.
- Mention if stools are hard, pellet-like, or painful to pass.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Your breastfed baby over 6 weeks goes several days without pooping but produces a large, soft stool when they finally go
- Your baby is happy, feeding well, and passing gas between bowel movements
- Poop frequency changed after starting solids but the stool is still soft
- Your baby strains with a red face but produces soft stool - this is normal infant dyschezia, not constipation
- Your formula-fed baby regularly goes 4+ days without pooping
- Stools are hard, pellet-like, or painful to pass
- Your baby cries during bowel movements and there is blood on the stool or diaper
- Your toddler is withholding stool and going several days between painful bowel movements
- A newborn under 6 weeks who has not passed meconium within 48 hours of birth or stops pooping
- Your baby has a distended (swollen, hard) belly with no bowel movement and is vomiting
- Blood in stool with severe abdominal pain and your baby drawing legs up - could indicate intussusception
What You Can Do at Home
- Keep track of when you notice baby not pooping for a week - when to worry — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that your breastfed baby over 6 weeks goes several days without pooping but produces a large, soft stool when they finally go — this is generally within the range of normal.
- At 0-6 weeks, 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 a newborn under 6 weeks who has not passed meconium within 48 hours of birth or stops pooping.
Related Conditions
Toddler Chronic Diarrhea (Toddler's Diarrhea)
Chronic diarrhea in an otherwise healthy, thriving toddler is very common and usually diagnosed as "toddler's diarrhea" (chronic nonspecific diarrhea of childhood). The child has 3-6+ loose stools per day, often with undigested food, but is growing well, eating normally, and is otherwise healthy. The most effective fix is dietary: limit juice to 4oz/day or less, increase dietary fat, and ensure adequate fiber. If your child is also losing weight, has blood in stool, or seems unwell, further evaluation is needed.
Toddler Complaining of Tummy Pain
Tummy pain is one of the most common complaints in toddlers. The most frequent cause by far is constipation, which can cause significant discomfort even when parents do not realize their child is constipated. Other common causes include gas, overeating, mild stomach bugs, food intolerances, and stress. While most tummy pain in toddlers is not serious, certain patterns - pain that wakes your child from sleep, pain localized to the right lower side, or pain with high fever and vomiting - should be evaluated promptly.
Baby Vomiting Without Fever
Vomiting without fever in babies has many possible causes, and most are not serious. Common reasons include overfeeding, reflux, food intolerance, motion sickness, or a sensitive gag reflex. However, certain patterns - forceful projectile vomiting in a young infant, bile-stained (green) vomit, or vomiting that prevents any fluid intake - can signal conditions that need prompt medical attention.

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.
