My Toddler Holds In Their Poop
The short answer
Stool withholding is very common in toddlers and is often triggered by a painful bowel movement that makes the child afraid to poop again. It can also emerge during potty training when children feel pressure or anxiety about using the toilet. The resulting cycle of withholding, harder stools, and pain can be frustrating, but it is highly treatable with a combination of stool softeners, dietary changes, and patient, pressure-free encouragement.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
12-18 months
Stool withholding can begin at this age, usually triggered by a single painful bowel movement that frightens the child. You may notice your toddler stiffening their legs, clenching their buttocks, crossing their legs, or hiding in a corner when they feel the urge to poop. They are not trying to be difficult - they are genuinely trying to avoid pain. Talk to your pediatrician about using a stool softener to break the cycle and make bowel movements comfortable again.
18-24 months
This age marks the beginning of potty training readiness for some children, and introducing the toilet too early or with too much pressure can trigger stool withholding. If your child is withholding, it is best to pause potty training and focus first on making pooping comfortable and painless. Continue using diapers or pull-ups without shame, soften stools with medication if recommended by your pediatrician, and offer high-fiber foods and plenty of water.
24-30 months
Stool withholding is most common during active potty training. Many toddlers will urinate on the toilet successfully but insist on a diaper for bowel movements. This is a normal transitional stage. Allowing your child to poop in a diaper while continuing to work on comfort and confidence is far better than forcing toilet use and worsening the withholding cycle. Reading books about pooping, using a step stool for proper posture, and celebrating small steps all help.
30-36 months
If stool withholding has been ongoing, your child may have developed a pattern of chronic constipation where the rectum has stretched to accommodate large, hard stools. This can reduce the urge to go and may lead to soiling accidents (encopresis). Your pediatrician may recommend a longer course of stool softeners to allow the rectum to return to its normal size, along with a consistent toileting routine. Resolution takes time but is very achievable with patience and medical support.
What Should You Do?
When to take action
- Your toddler occasionally resists pooping for a day but eventually goes without significant distress
- Your child prefers to poop in a diaper rather than on the toilet during potty training but is pooping regularly
- Your child briefly stiffens or hides when they feel the urge but then has a normal bowel movement
- Your child's withholding behavior is improving with dietary changes and encouragement
- Your toddler is regularly withholding stool for three or more days at a time, resulting in large, painful bowel movements
- Stool withholding is significantly interfering with potty training progress or causing your child distress
- Your child has developed a pattern of soiling accidents (small amounts of stool leaking into underwear) between large bowel movements
- Your child has not had a bowel movement in over a week and has abdominal pain, distension, or vomiting
- Your child is in severe pain, has blood in the stool, or is refusing to eat due to discomfort from stool withholding

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.
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.
Dark Blood in Baby's Stool
Dark or black blood in stool (melena) is different from bright red blood and may indicate bleeding from the upper digestive tract (stomach or upper intestine). In newborns, black stools in the first few days (meconium) are normal. Beyond the first week, dark, tarry, or coffee-ground-like material in stool needs prompt medical evaluation. Some dark-colored foods and iron supplements can also darken stools without being blood.
