Your child is straining on the toilet. Crying. Holding their belly. You’re worried and want to help—but many adult remedies aren’t safe for children.
The good news: Constipation is extremely common in children (affecting up to 30% at some point) and usually responds well to gentle, age-appropriate interventions.
The reality: Pediatric constipation is different from adult constipation. Children’s digestive systems are still developing. Their symptoms present differently. And treatments must be carefully dosed for their size and developmental stage.
This guide covers:
- What’s normal for children at different ages
- Age-specific signs of constipation (babies can’t tell you they’re uncomfortable)
- Common causes unique to children
- Safe, gentle remedies by age group
- When to call your pediatrician
- How to prevent future episodes
- Red flags that need prompt medical attention
Understanding Pediatric Constipation
What’s Normal for Children?
Normal bowel frequency varies dramatically by age:
| Age | Normal Frequency | Normal Stool Consistency |
|---|---|---|
| Newborn (0-1 month) | 3-12 times/day (breastfed); 1-4 times/day (formula) | Soft, seedy (breastfed); pasty (formula) |
| Infant (1-6 months) | 1-4 times/day to once every 3-4 days (breastfed) | Soft, formed |
| Infant (6-12 months) | 1-2 times/day | Soft, formed |
| Toddler (1-3 years) | 3 times/day to 3 times/week | Soft, formed |
| Preschool (3-5 years) | 1-2 times/day to 3 times/week | Soft, formed (Bristol 3-4) |
| School age (5-12 years) | 1-2 times/day to once every 2 days | Soft, formed (Bristol 3-4) |
| Teenagers | Daily to every other day | Soft, formed (Bristol 3-4) |
Key insight: Breastfed infants can go 3-4 days (sometimes up to 7-10 days) without a bowel movement and still be normal, as long as stool is soft when it comes and baby is comfortable.
Medical Definition of Constipation in Children
According to Rome IV criteria for pediatric functional constipation:
For infants and toddlers (up to 4 years): At least 2 of these for 1 month:
- 2 or fewer bowel movements per week
- At least one episode per week of fecal incontinence (after potty training)
- History of retentive posturing (withholding behavior)
- History of painful or hard bowel movements
- Presence of large fecal mass in rectum
For children and adolescents (4+ years): At least 2 of these for 2 months:
- 2 or fewer bowel movements in the toilet per week
- At least one episode per week of fecal incontinence
- History of retentive posturing or excessive stool retention
- History of painful or hard bowel movements
- Presence of large fecal mass in rectum
- History of large diameter stools that may clog toilet
Age-Specific Signs of Constipation
Newborns and Young Infants (0-6 Months)
Babies can’t tell you they’re constipated. Watch for:
| Sign | What You’ll See |
|---|---|
| Hard, pellet-like stools | Small, hard balls instead of soft/pasty |
| Straining and crying | More than 10 minutes of hard straining |
| Blood in stool | Small streaks from anal fissures |
| Decreased feeding | Not interested in feeding as usual |
| Fussiness | More irritable than usual |
| Firm belly | Abdomen feels hard or distended |
| Infrequent stools | Less than usual FOR YOUR BABY (breastfed babies vary widely) |
Important: Breastfed babies often strain, turn red, and cry before passing a SOFT stool. This is called infant dyschezia and is NORMAL—not constipation. The baby is learning to coordinate muscles. As long as stool is soft, this isn’t constipation.
Red flags in young infants:
- No meconium (first black stool) in first 48 hours of life
- Constipation since birth
- Poor weight gain
- Vomiting (especially green/bilious)
- Distended, firm abdomen
- Blood in stool (more than tiny streaks)
Older Infants (6-12 Months)
Signs of constipation:
| Sign | What You’ll See |
|---|---|
| Hard, dry stools | Pellet-like or large, hard logs |
| Straining and crying | During bowel movements |
| Infrequent stools | Less than 3 per week |
| Withholding behavior | Arching back, clenching buttocks, crying |
| Decreased appetite | Not eating as much |
| Fussiness | More irritable, especially around diaper changes |
| Blood streaks | On stool or wipe (from fissures) |
Common triggers at this age:
- Introduction of solid foods
- Transition from breast milk to formula
- Starting cow’s milk (after 12 months)
- Dehydration (especially with illness)
Toddlers (1-3 Years)
Signs of constipation:
| Sign | What You’ll See |
|---|---|
| Hard, large stools | May clog toilet |
| Painful bowel movements | Crying, resistance to using potty |
| Withholding behaviors | Crossing legs, dancing, hiding, refusing potty |
| Infrequent bowel movements | Less than 3 per week |
| Accidents | Soiling underwear (encopresis) |
| Large stools | unusually large diameter |
| Stool hiding | Going behind furniture to withhold |
| Behavioral changes | Irritability, sleep disruption |
Withholding cycle (very common in toddlers):
- Child has painful bowel movement
- Child associates pooping with pain
- Child holds stool to avoid pain
- Stool becomes larger and harder in colon
- Next bowel movement is even more painful
- Cycle continues and worsens
Common triggers at this age:
- Toilet training (starting too early or pressure)
- Changes in routine (daycare, new sibling, move)
- Not wanting to use public/school bathrooms
- Too busy playing to stop for bathroom
- Dietary changes (more cow’s milk, less fiber)
Preschool and School-Age (3-12 Years)
Signs of constipation:
| Sign | What You’ll See |
|---|---|
| Infrequent bowel movements | Less than 3 per week |
| Hard, large stools | May clog toilet |
| Painful bowel movements | Complains of pain |
| Fecal soiling | Stool accidents in underwear (encopresis) |
| Abdominal pain | Complaints of tummy ache |
| Decreased appetite | Not hungry, especially at meals |
| Withholding behaviors | May still cross legs, fidget |
| School avoidance | Doesn’t want to go to school (bathroom issues) |
| Mood changes | Irritable, withdrawn |
What children might say:
- “My tummy hurts”
- “It hurts to poop”
- “I don’t need to go” (when they clearly do)
- “I’m afraid to use the school bathroom”
Common triggers at this age:
- School bathroom avoidance
- Not enough fiber in diet
- Not drinking enough water

- Holding stool during school day
Teenagers
Signs of constipation:
| Sign | What You’ll See |
|---|---|
| Infrequent bowel movements | Less than 3 per week |
| Hard, difficult stools | Straining, pain |
| Feeling of incomplete evacuation | Still feels backed up after going |
| Abdominal pain/bloating | Complaints of discomfort |
| Fecal soiling (less common) | May occur with severe impaction |
| Mood changes | Irritability, anxiety |
| Avoiding activities | Due to discomfort |
What teenagers might report:
- “I’m always bloated”
- “I can never fully empty”
- “It hurts when I go”
- “I don’t have time” (busy schedules)
- Embarrassment discussing bowel habits
Common triggers at this age:
- Busy schedules (no time for bathroom)
- Poor diet (fast food, low fiber)

- Stress (school, social, activities)
- Eating disorders (restriction affects bowel function)
- Medications (ADHD meds, antidepressants, birth control)
- Ignoring urges
Common Causes of Constipation in Children
Functional Constipation (Most Common - 95% of Cases)
What it is: Constipation without an underlying medical condition.
Why it happens:
- Painful bowel movement starts the cycle
- Withholding behavior to avoid pain
- Stool sits in colon, becomes harder and larger
- Next bowel movement more painful
- Cycle continues
Triggers:
- Toilet training issues
- Dietary changes
- Dehydration
- Stress or changes in routine
- Holding stool (school, activities)
Dietary Causes
Not Enough Fiber
Why it matters: Fiber adds bulk and speeds transit through the colon.
Recommended daily fiber for children:
| Age | Daily Fiber Goal |
|---|---|
| 1-3 years | 19g |
| 4-8 years | 25g |
| Girls 9-13 years | 26g |
| Boys 9-13 years | 31g |
| Girls 14-18 years | 26g |
| Boys 14-18 years | 38g |
Simple formula: Child’s age + 5 = grams of fiber per day (for ages 2+)
Common low-fiber diet patterns:
- Lots of processed foods
- Not enough fruits and vegetables
- Too much dairy
- Refined grains (white bread, white rice)
Too Much Dairy
Why it matters: Cow’s milk protein can slow motility in some children.
Problem patterns:
- More than 16-24 oz of cow’s milk daily (toddlers)
- Lots of cheese
- Milk-based meals (cereal with milk, cheese sandwiches, yogurt)
Recommendations:
- Limit cow’s milk to 16-20 oz daily for toddlers
- Ensure adequate fiber alongside dairy
- Consider if dairy reduction helps (discuss with pediatrician)
Not Enough Fluids
Why it matters: Dehydration leads to harder stools.
Recommended daily fluid intake:
| Age | Daily Fluid Goal |
|---|---|
| 1-3 years | 4 cups (32 oz) |
| 4-8 years | 5 cups (40 oz) |
| 9-13 years | 7-8 cups (56-64 oz) |
| 14-18 years | 8-11 cups (64-88 oz) |
Signs of adequate hydration:
- Pale yellow urine
- Urinating every 2-4 hours
- Moist lips and mouth
Toilet Training Issues
Common problems:
| Issue | Why It Causes Constipation |
|---|---|
| Starting too early | Child not developmentally ready; resists |
| Too much pressure | Creates anxiety around toileting |
| Punishment for accidents | Child associates toileting with negativity |
| Inconsistent routine | Child doesn’t develop regular habits |
| Public/school bathroom avoidance | Child holds stool during day |
Best practices:
- Wait until child shows readiness signs (usually 18-36 months)
- Keep it positive and low-pressure
- Establish regular toilet routine (after meals)
- Use footstool for proper positioning
- Praise attempts, not just success
Psychological and Behavioral Factors
Stress and Anxiety
How it affects bowels:
- Stress hormones slow gut motility
- Anxiety increases muscle tension (including pelvic floor)
- Children may hold stool when stressed
Common stressors:
- New sibling
- Starting daycare/school
- Family conflict
- Move to new home
- Trauma or abuse
School Bathroom Avoidance
Why children hold stool:
- Lack of privacy
- Fear of germs
- Embarrassment
- Not enough time
- Uncomfortable with school bathroom environment
Impact:
- Child holds stool all day
- Stool becomes harder
- Painful to pass
- Cycle continues
Solutions:
- Talk to teacher about bathroom access
- Establish morning bowel routine at home
- Practice relaxation techniques
- Consider 504 plan if chronic
Medication Side Effects
Common medications that cause constipation in children:
| Medication | Used For | Constipation Risk |
|---|---|---|
| Iron supplements | Anemia | High |
| Antihistamines | Allergies | Moderate |
| ADHD medications | ADHD | Moderate |
| Antidepressants | Depression, anxiety | Moderate |
| Antacids (calcium/aluminum) | Reflux | Moderate |
| Opioid pain medications | Pain | High |
| Anticholinergics | Various conditions | Moderate |
What to do:
- Don’t stop prescribed medication without consulting doctor
- Ask about alternatives if constipation severe
- Implement preventive bowel regimen
- Ensure adequate fiber and fluids

Gentle, Age-Appropriate Solutions
For Infants (0-6 Months)
Important: Always consult your pediatrician before giving any remedies to young infants.
Safe approaches:
Breastfed Infants
Usually DON’T need treatment if:
- Stool is soft when it comes
- Baby is gaining weight well
- Baby is comfortable between stools
Remember: Breastfed infants can go 3-7 days (sometimes 10+) without stooling and still be normal.
Gentle interventions:
- Bicycle legs: Gently move baby’s legs in bicycling motion
- Tummy massage: Gentle clockwise massage around belly button
- Warm bath: Can help relax muscles
- Extra nursing: Breast milk has natural laxative effect
When to call pediatrician:
- Hard, dry stools
- Blood in stool
- Poor weight gain
- Vomiting
- Distended, firm abdomen
- No stool for 10+ days (even if breastfed)
Formula-Fed Infants
Gentle interventions:
- Check formula preparation: Ensure correct water-to-formula ratio
- Bicycle legs: Gentle leg movements
- Tummy massage: Clockwise around belly button
- Warm bath: Helps relax muscles
- Small amount of water: 1-2 oz once or twice daily (only if over 1 month old and with pediatrician approval)
- Fruit juice: 1-2 oz of prune, pear, or apple juice daily (only if over 1 month old and with pediatrician approval)
Formula considerations:
- Some formulas are constipating for some babies
- Discuss formula change with pediatrician if constipation persistent
- Don’t switch formulas frequently without medical guidance
For Older Infants (6-12 Months)
Safe interventions:
Dietary Changes
High-fiber baby foods:
- Pureed prunes, pears, peaches, plums (“P fruits”)
- Pureed peas, beans
- Oatmeal or barley cereal instead of rice cereal
- Pureed broccoli, spinach
Fruit juice: 2-4 oz of prune, pear, or apple juice daily (can dilute with water)
Water: Offer 2-4 oz water between feedings
Avoid:
- Too much rice cereal (can be constipating)
- Too much banana (especially unripe)
- Too much dairy (if introduced)
Physical Measures
- Bicycle legs: Gentle leg movements
- Tummy massage: Clockwise around belly button
- Warm bath: Helps relax muscles
- Tummy time: Increases abdominal pressure and movement
When Diet Isn’t Enough
With pediatrician approval:

- Use footstool for proper positioning (knees higher than hips)
- Keep it relaxed and positive
- Read books, sing songs, don’t pressure
- Praise sitting, not just success
Behavioral Strategies
For withholding:
- Stay calm and positive
- Don’t punish for accidents
- Use sticker chart for sitting on potty (not just for results)
- Address fear of toilet (some toddlers fear falling in)
- Consider pausing toilet training if too much resistance
For toilet training issues:
- Watch for readiness signs
- Don’t start during major life changes
- Keep it positive
- Consider waiting if significant resistance
Medications (With Pediatrician Guidance)
First-line:
- Polyethylene glycol (Miralax): ½ to 1 capful (8.5-17g) daily in 4-8 oz liquid
- Start low, adjust based on response
- Safe for long-term use
- Goal: 1-2 soft bowel movements daily
If Miralax not enough:
- Lactulose: Prescription osmotic laxative
- Glycerin suppository: For occasional immediate relief
For disimpaction (if severely backed up):
- Higher dose Miralax (as directed by pediatrician)

Frequently Asked Questions
How long can a child go without a bowel movement before I should worry?
Depends on age:
| Age | When to Worry |
|---|---|
| 0-6 months (breastfed) | 10+ days without stool, OR hard stools, OR poor feeding/growth |
| 0-6 months (formula) | 3-4 days without stool, OR hard stools |
| 6-12 months | 3+ days without stool, OR hard/painful stools |
| 1-3 years | 4+ days without stool, OR painful/hard stools |
| 3+ years | 5+ days without stool, OR any red flag symptoms |
More important than frequency: Stool consistency and comfort. Soft, painless stools are more important than daily frequency.
Is Miralax safe for children?
Yes, polyethylene glycol (Miralax) is considered safe for children when used as directed.
What pediatricians say:
- First-line treatment for pediatric constipation
- Safe for long-term use (months to years)
- Not absorbed into bloodstream (works locally in colon)
- Minimal side effects
Important:
- Use pediatrician-recommended dosing
- Continue for months, not days (relapse common if stopped too soon)
- Combine with dietary and behavioral strategies
- Follow up with pediatrician regularly
Can I give my baby prune juice?
Age guidelines:
- Under 1 month: No (consult pediatrician first)
- 1-6 months: 1-2 oz diluted with water, with pediatrician approval
- 6-12 months: 2-4 oz daily, can be undiluted
Tips:
- Dilute with water for younger infants
- Can mix with formula or breast milk
- Prune puree also effective for older infants
What’s encopresis and how is it treated?
Encopresis is fecal soiling—involuntary leakage of stool into underwear.
Why it happens:
- Stool backs up in colon (impaction)
- Liquid stool leaks around the hard mass
- Child may not feel it happening
- Often mistaken for diarrhea
Treatment:
- Disimpaction: Clear the backed-up stool (Miralax, sometimes enemas)
- Maintenance: Keep stool soft for months (Miralax daily)
- Toilet routine: Regular sitting after meals
- Behavioral: Positive reinforcement, no punishment
- Time: Colon needs months to return to normal size
Important: Don’t punish for accidents—it’s not the child’s fault.
Should I stop toilet training if my child gets constipated?
Often yes. Consider pausing if:
- Child is resisting strongly
- Constipation is worsening
- Lots of accidents and frustration
- Child seems anxious about toileting
When to resume:
- Bowel movements are soft and regular
- Child shows interest again
- Less resistance
- Discuss with pediatrician
Prevention:
- Wait for readiness signs
- Keep it positive
- Don’t start during major changes
- Use footstool for proper positioning
Can food allergies cause constipation in children?
Yes, cow’s milk protein allergy/intolerance can cause constipation in some children.
Signs it might be milk-related:
- Constipation started after introducing cow’s milk
- Other symptoms (eczema, reflux, fussiness)
- Family history of allergies
- Improves when dairy reduced/eliminated
What to do:
- Discuss with pediatrician
- May try dairy elimination trial (2-4 weeks)
- Don’t eliminate major food groups without medical guidance
- Ensure adequate calcium and vitamin D
How do I prevent my child from getting constipated at school?
Strategies:
- Establish reliable morning toilet routine at home
- Talk to teacher about unrestricted bathroom access
- Pack high-fiber lunch and snacks
- Send water bottle
- Practice relaxation techniques for bathroom anxiety
- Consider 504 plan for chronic issues
- Ask child about school bathroom (privacy, cleanliness)
- Encourage after-school toilet time
When does constipation need specialist care?
See pediatric gastroenterologist if:
- Constipation since birth
- Failure to thrive
- Not responding to aggressive treatment
- Need for repeated disimpaction
- Suspected underlying condition (Hirschsprung, celiac, thyroid)
- Severe encopresis
- Significant quality of life impact
- Need for specialized testing
Key Takeaways
- Constipation is very common in children (up to 30%) and usually manageable
- Normal bowel frequency varies by age—breastfed infants can go days without stooling
- Withholding behavior is common in toddlers and requires gentle, consistent approach
- Dietary changes help—adequate fiber, fluids, limited dairy
- Miralax is safe for children when used as directed by pediatrician
- Treatment takes months, not days—relapse common if stopped too soon
- Toilet routine matters—regular sitting after meals, proper positioning
- School bathroom avoidance is real—work with school on accommodations
- Red flags need prompt evaluation—constipation from birth, poor growth, severe symptoms
- Don’t punish for accidents—encopresis is involuntary and requires medical treatment
