Digestive issues are common in infants and toddlers. If your baby is experiencing straining and grunting to poop (infant dyschezia), here is what you need to know.
The short answer
Straining, grunting, and turning red during bowel movements is very common in newborns and is called infant dyschezia. It occurs because babies are learning to coordinate relaxing the pelvic floor while bearing down with the abdomen. It is NOT constipation as long as the stool is soft. It typically resolves by 3-4 months.
Key takeaways
- Straining, grunting, and turning red during bowel movements is very common in newborns and is called infant dyschezia. It occurs because babies are learning to coordinate relaxing the pelvic floor while bearing down with the abdomen. It is NOT constipation as long as the stool is soft. It typically resolves by 3-4 months.
- Usually normal when: Straining, grunting, and turning red for minutes before passing a SOFT stool
- Call your doctor if: No stool for more than 5-7 days in a young infant, especially if accompanied by abdominal distension or 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.”
Parents everywhere have the same worry. You are doing the right thing by looking into it.
What Parents Should Know
According to AAP, NIH guidelines, straining, grunting, and turning red during bowel movements is very common in newborns and is called infant dyschezia. It occurs because babies are learning to coordinate relaxing the pelvic floor while bearing down with the abdomen. It is NOT constipation as long as the stool is soft. It typically resolves by 3-4 months. At 0-1 month, infant dyschezia is very common and can be distressing to watch. Your baby may grunt, strain, cry, and turn red or purple for 10-20 minutes before successfully passing a soft stool. The key distinction from constipation is that the stool, when it comes, is soft and normal in consistency. Your baby is simply learning the complex coordination required for a bowel movement. Do not use stimulation (rectal thermometers, suppositories) to help them poop, as this can prevent them from learning the coordination on their own. It is generally considered normal when straining, grunting, and turning red for minutes before passing a SOFT stool. However, you should contact your pediatrician promptly if no stool for more than 5-7 days in a young infant, especially if accompanied by abdominal distension or vomiting.
Normal vs. Concerning
By Age
What to expect by age
0-1 month
Infant dyschezia is very common and can be distressing to watch. Your baby may grunt, strain, cry, and turn red or purple for 10-20 minutes before successfully passing a soft stool. The key distinction from constipation is that the stool, when it comes, is soft and normal in consistency. Your baby is simply learning the complex coordination required for a bowel movement. Do not use stimulation (rectal thermometers, suppositories) to help them poop, as this can prevent them from learning the coordination on their own.
1-3 months
Dyschezia typically continues and then resolves by 3-4 months as your baby learns to coordinate pelvic floor relaxation. It may get worse before it gets better. Continue to avoid rectal stimulation. If stools become hard, dry, or pellet-like, that is actual constipation and should be discussed with your pediatrician.
3-6 months
Most cases of dyschezia resolve during this period. Your baby's abdominal muscles and pelvic floor coordination improve with maturity.
6-12 months
Dyschezia should be resolved. Straining with hard stools at this age is likely constipation, which can occur with the introduction of solid foods.
What to Tell Your Pediatrician
- Describe when you first noticed straining and grunting to poop (infant dyschezia) and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if straining produces hard, dry, or pellet-like stools (actual constipation).
- Mention if baby is in significant distress for extended periods.
- 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
- Straining, grunting, and turning red for minutes before passing a SOFT stool
- Baby is otherwise comfortable between episodes
- The stool, when produced, is normal in consistency
- Episodes gradually decrease in frequency and intensity over weeks
- Straining produces hard, dry, or pellet-like stools (actual constipation)
- Baby is in significant distress for extended periods
- You are tempted to use rectal stimulation and want guidance
- No stool for more than 5-7 days in a young infant, especially if accompanied by abdominal distension or vomiting
- Blood in the stool or around the anus after straining
What You Can Do at Home
- Keep track of when you notice straining and grunting to poop (infant dyschezia) — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that straining, grunting, and turning red for minutes before passing a SOFT stool — this is generally within the range of normal.
- At 0-1 month, 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 no stool for more than 5-7 days in a young infant, especially if accompanied by abdominal distension or vomiting.

Grunting Sounds in Newborns
Grunting in newborns is very common and usually normal. Babies grunt during sleep as they learn to coordinate their breathing, and they grunt while straining to have a bowel movement (grunting baby syndrome or infant dyschezia). However, continuous grunting with every breath, especially if accompanied by other signs of breathing difficulty, requires immediate medical attention.
Gas Discomfort in Newborns
Gas is very common in newborns because their digestive systems are immature. Signs include fussiness, pulling legs up, a hard or distended tummy, and excessive flatulence. Burping during and after feeds, bicycle leg exercises, tummy time, and gentle tummy massage can help. Gas drops (simethicone) are safe but have limited evidence of effectiveness.
Going Days Without Pooping (Breastfed Baby)
After the first month or so, it is completely normal for breastfed babies to go several days (sometimes up to 7-10 days) between bowel movements. This is because breast milk is so efficiently absorbed that there is little waste. This is NOT constipation as long as the stool is soft when it does come. Formula-fed babies, however, should have more regular stools.

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.
