Toddler Constipation - Causes, Signs, Home Remedies, and When to See a doctor

Published - April 2025 Last Updated - April 2026

Your toddler has not gone in three days. They are uncomfortable. They keep going on their tiptoes and doing a strange dance that is clearly not for fun.

Toddler constipation is extremely common and almost always manageable. But it is uncomfortable for your child and stressful for you, especially when you are not sure what is causing it or how long to wait before calling the doctor.

This guide covers exactly what constipation looks like in toddlers, why it happens, what works at home, and the signs that need professional attention.

What Is Toddler Constipation?

Constipation in toddlers means pooping less than usual, with hard, dry, or painful stools.

Cleveland Clinic defines it clearly: constipated toddlers typically poop less than two times a week. Their stools come out unusually large, firm, and lacking moisture. When they do go, it is painful to pass.

All toddlers' bowel habits are different. Some poop twice a day. Some poop every other day. Constipation is not defined by a strict number; it is defined by a change from the child's normal pattern, combined with hard, difficult stools.

Fact from the NIDDK (National Institutes of Health) - Children most often get constipated from holding in their stool. When stool stays too long in the colon, the colon absorbs too much fluid from it. The stool then becomes hard, dry, and difficult to pass, which creates a painful cycle that makes children hold it even more.

What are the signs of toddler constipation?

Your toddler may not tell you they are constipated. Watch for these signs.

Physical signs

• Pooping less than two times a week
• Hard, lumpy, or unusually large stools
• Straining and obvious discomfort when trying to poop
• Stomach swelling or cramping
• Small amounts of liquid or soft stool in the nappy or underwear can actually indicate severe constipation, where only the softest stool passes around a blockage

Behavioural signs

• Standing on tiptoes
• Rocking back and forth
• Crossing their legs
• Moving away from you or hiding
• Refusing to sit on the toilet or potty

The unusual postures are the toddler's body trying to avoid or delay a bowel movement, because they know it will hurt or because they do not want to stop what they are doing.

Why does toddler constipation happen?

Holding It In

This is the most common cause by far. Toddlers hold in their stool for many reasons.

They do not want to stop playing. They feel uncomfortable and self‑conscious about using bathrooms in public places. They had a painful experience once and are now anxious about going again. Potty training introduces new expectations that feel stressful.

Once stool is held in and becomes harder, defecation becomes more painful, which creates a cycle of holding and more constipation.

Diet

A low-fibre diet is a primary dietary driver. Too much dairy (cheese, cow's milk), not enough fruit and vegetables, and not enough fluid intake all contribute.

The AAP recommends that children between the ages of 2 and 19 consume at least 5 grams of fibre per day, plus their age in grams. A 3-year-old needs about 8 grams per day.

Mayo Clinic notes that switching from a liquid to a solid diet is a common time for constipation to begin, which is why it often peaks in the toddler years as dietary variety expands.

Changes in Routine

Travel, hot weather, starting childcare, stress, illness, or any significant change in daily routine can disrupt bowel patterns.

Cow's Milk Intolerance

Some children are sensitive to cow's milk protein. Too many dairy products, especially cheese, can cause or worsen constipation.

Medications

Some medications, including certain antihistamines and iron supplements, can cause constipation as a side effect. If constipation began when the medication was started, mention this to your doctor.

Practical Home Remedies for Toddler Constipation

Increase Fibre-Rich Foods

Add more fruits and vegetables to daily meals. These are particularly effective:

• Prunes (extremely effective, even small amounts work)
• Pears and apples
• Peaches
• Broccoli
• Beans and lentils
• Whole-grain bread and oats

CHOC Children's Hospital recommends fruit juices from prunes, apples, peaches, and pears specifically. These fruits are high in sorbitol, a natural sugar that acts as a mild laxative by retaining water in the stool.

Increase Fluids

Water helps keep stools soft. Make water the default drink throughout the day. Limit milk to the recommended amount (around 500ml per day for toddlers) to prevent it from displacing higher-fibre foods and fluids.

Reduce Dairy

Too much cheese and milk is one of the most common dietary causes of toddler constipation. If your child eats large amounts of dairy daily, reducing it often produces quick improvement.

Establish a Bathroom Routine

Create a regular toilet or potty time after meals, ideally after breakfast or dinner when the gastrocolic reflex is active. This is when the digestive system naturally signals the colon to move.

Sit your toddler on the toilet or potty for 5 to 10 minutes after eating. Use a step stool so their feet are supported. This posture makes passing stool easier.

Keep it positive and pressure-free. Praising the attempt, not just success, helps children feel safe rather than anxious about the toilet.

Physical Activity

Movement helps stimulate digestion. Encourage running, jumping, and active play every day. This is one more reason toddler physical activity matters beyond fitness.

Tummy Massage

A gentle clockwise tummy massage can help stimulate bowel movement. Follow the direction of digestion — starting at the lower right side, moving up, across, and down the left side.

When Should You Call the Doctor?

Most toddler constipation resolves with dietary and routine changes. But some situations require professional attention.

Call your pediatrician if -

• Constipation lasts longer than 2 weeks
• Home remedies are not working
• Your child has blood in the stool
• Your child has blood from the rectum
• Constipation is accompanied by vomiting or fever
• Your child has significant abdominal swelling
• Your child is losing weight or not gaining weight
• Your toddler is withholding stools so severely that it is affecting daily life

The NIDDK advises calling a doctor right away if constipation lasts longer than two weeks or if any of the above symptoms occur alongside it.

What will the doctor do?

Diagnosis

In most cases, diagnosis is based on symptoms and a physical examination. No tests are needed. The doctor may ask about your toddler's diet, bowel frequency, stool consistency, and how long the problem has been happening.

For more persistent cases, doctors may order an abdominal X-ray to see the amount of stool in the colon, or blood tests to rule out thyroid problems, coeliac disease, or anemia.

Treatment Options

Dietary changes are always the first line. Increasing fibre and fluids and reducing dairy.

Stool softeners such as polyethylene glycol (Miralax) are commonly used and considered safe for children, with very few side effects. Johns Hopkins Medicine confirms they are not habit-forming and can be taken for an extended period.

Clean-out first - For severe or long-standing constipation, Dr. Rosen at Yale Medicine explains that a "clean-out" procedure, a short course of high-dose laxative, may be needed first to clear the backlog before maintenance treatment begins. This is typically followed by long-term maintenance medication that is gradually weaned.

Toddler Constipation and Potty Training

Potty training and constipation often collide.

Many children withhold stools during potty training because they feel anxious about the process, are afraid of the toilet, or simply do not want to stop playing to use it. This withholding can quickly become chronic constipation.

If constipation is severe during potty training, it is sometimes worth pausing the training process temporarily while addressing the constipation medically. A constipated child who is also stressed about the toilet is in a difficult position.

Restarting potty training on softer, more manageable stools usually goes much better.
