Straining and Grunting to Poop (Infant Dyschezia)
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.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
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.
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.
Most cases of dyschezia resolve during this period. Your baby's abdominal muscles and pelvic floor coordination improve with maturity.
Dyschezia should be resolved. Straining with hard stools at this age is likely constipation, which can occur with the introduction of solid foods.
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

Related Digestive Concerns
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.
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.
