Constipation in Toddlers Aged 13 to 18 Months

Read the UK edition

The short answer

Constipation is not defined only by how often a child poops. Hard, dry, painful stools and stool withholding can also be signs. Offer water and a varied diet, but do not start laxatives, suppositories, enemas, or supplements without advice. Seek care for persistent symptoms or red flags such as blood, ongoing pain, vomiting, or weight loss.

Keep in mind

  • Stool consistency and discomfort matter as well as frequency.
  • Offer varied fiber-containing foods and regular access to water; one food or extra water may not resolve constipation.
  • Do not give constipation medicines or remedies without a clinician’s advice.

Is constipation only infrequent pooping?

No. Some children have a bowel movement every day and others less often. Frequency varies from child to child.

Hard, dry, lumpy stools or painful and difficult bowel movements can also indicate constipation. Consider what is normal for your child and whether the stool is hard or uncomfortable to pass.

What stool signs can suggest constipation?

Stools that are hard, dry, unusually large, or like small pellets may be a sign. Crying or straining because it hurts is also important.

Soft stool that passes comfortably may be normal even if it does not happen every day. A hard stool can cause a small tear around the anus and a little bright red blood; contact a clinician if you notice blood.

A child’s pattern over time is more useful than one bowel movement in isolation.

What can stool withholding look like?

A toddler may stiffen, squeeze their legs together, rise onto tiptoes, hide, or clench their bottom to avoid passing stool.

After a painful bowel movement, a child may try to hold the next one. Stool can then remain in the bowel longer and become harder, reinforcing the cycle.

How much do food and fluids matter?

Not drinking enough and eating few fiber-containing foods may contribute to constipation. Offer water and a variety of fruit, vegetables, beans, and grains.

A varied diet supports general health, but adding one food or encouraging extra water will not resolve every case of constipation.

If symptoms are significant or keep returning, a clinician can help look for causes and an appropriate plan.

Does milk cause constipation?

Milk is not the cause of constipation for every child. However, frequent milk drinks may leave some toddlers less interested in other foods that provide fiber.

Consider the whole pattern: what your child eats and drinks, their appetite, and their growth. A child with a diagnosed allergy or special dietary need needs individualized guidance.

Do not remove dairy or make a major diet change without discussing it with a clinician if you have concerns.

Can constipation affect how a child feels?

A constipated child may have bloating, reduced appetite, or distress before a bowel movement. Some children may have loose stool leaking around a hard stool.

That leakage can be mistaken for ordinary diarrhea. Ongoing stool withholding can lead to a build-up, so persistent symptoms deserve assessment.

One unsettled day alone does not establish constipation; look at stool texture, discomfort, withholding, and the overall pattern.

What should you avoid doing at home?

Do not start laxatives, suppositories, enemas, herbal products, or supplements on your own. Ask your child’s clinician what is suitable, including for over-the-counter products.

Do not force toilet training or make a toddler sit for a long time on a potty. Pressure and blame can make painful withholding worse.

Keep routines calm and offer food and drinks without turning bowel movements into a struggle.

When should you contact a pediatric clinician?

Contact a clinician if symptoms last more than two weeks, recur often, or continue despite basic food and fluid routines.

Seek prompt advice for blood in or on the stool, ongoing abdominal pain, marked swelling, vomiting, or weight loss.

Get help sooner if your child cannot drink, appears very unwell, or you are strongly concerned.

What can you do today?

Notice stool texture and whether your child seems to be in pain; frequency alone does not tell the whole story.

Offer regular access to water and a range of fruit, vegetables, beans, and grains. Do not treat one food as a cure.

If your child hides, stiffens, or squeezes their legs to avoid a bowel movement, respond calmly rather than calling it misbehavior.

Contact a clinician for blood, persistent pain, vomiting, marked swelling, weight loss, or ongoing constipation.

When to seek support

Some signs need emergency help; other concerns can be discussed with your child’s healthcare team.

  • Contact a clinician if constipation lasts more than two weeks or keeps returning.
  • Seek prompt care for blood in stool, persistent abdominal pain or swelling, vomiting, weight loss, or a child who appears very unwell.
