Best Drinks for Constipation in Kids

Partly: water can help soften stools when a child is not drinking enough, while certain fruit juices can draw water into the bowel.

Which drinks are best for constipation in kids?

For children old enough to have them, water is the usual first choice, and a small amount of 100% prune, pear or apple juice is another option. For babies, the right choice depends on age; breast milk or properly prepared infant formula remains the main drink during the first year.

There is limited evidence comparing specific drinks for childhood constipation. A review of constipation in children and adults describes toilet training and laxatives as initial treatments for children, but it does not establish a best drink. Drinks may support a treatment plan, but they do not replace an assessment or prescribed treatment when needed.

For a broader overview, see the best drinks for constipation.

Water

Offer water regularly to a child who is old enough to drink it, especially if they have not been drinking much. Adequate fluid helps prevent stools from becoming harder because of dehydration. Drinking extra water is less likely to solve constipation when a child is already getting enough fluid.

Water is a practical everyday choice because it contains no sugar. Offer it with meals and between meals rather than trying to make a child drink a large amount at once.

Prune juice

Prune juice contains sorbitol, a sugar that is not fully absorbed and can draw water into the bowel. For a child over age 1, a small serving of 100% prune juice may be worth trying within the daily juice limits below.

The right serving is not an established constipation treatment dose. Too much can cause loose stools or abdominal discomfort, so do not assume that more will work better.

Pear juice

Pear juice also contains sorbitol and is an option if a child prefers it to prune juice. Choose 100% juice rather than a sweetened juice drink, and count it toward the child's daily juice limit.

A child does not need to drink pear juice every day. If constipation is painful, persistent or recurrent, do not rely on juice alone to manage it.

Apple juice

Apple juice contains sorbitol and may help some children pass softer stools. As with pear and prune juice, offer a small amount of 100% juice rather than letting the child sip it throughout the day.

Apple juice is not proven to work better than the other choices. Taste, age and how the child responds can guide a family's choice, within the limits below.

Breast milk and infant formula

For a baby younger than 6 months, breast milk or infant formula provides the fluid they need unless their clinician advises otherwise. Do not add extra water to formula: prepare it exactly as directed on the package or by the baby's clinician.

Babies around 6 months who have started solid foods can be offered small amounts of water in a cup, while breast milk or formula remains their main drink. Contact the baby's clinician if you suspect constipation; do not give juice to a baby under 12 months unless the clinician specifically recommends it.

Why might these drinks help, and when can they be unsafe?

Water helps most when low fluid intake is contributing to constipation. It cannot reliably overcome other common factors, such as a child holding stool because passing it has hurt. A child can have constipation despite drinking adequately.

Prune, pear and apple juices work differently from plain water: their sorbitol can draw water into the bowel. The available review does not show how well these juices treat childhood constipation or which one works best, so consider them optional measures rather than proven replacements for treatment.

Juice contains sugar and can contribute to tooth decay, especially when sipped often or offered at bedtime. Serve it with a meal rather than in a bottle or a cup carried around all day. Whole fruit can provide fiber as well as fluid, whereas juice does not provide the same fiber benefit.

Cow's milk is not a reliable constipation remedy. Large amounts can crowd out water and fiber-containing foods; if you think milk is contributing to a child's constipation, discuss it with their clinician before making major dietary changes. Cow's milk should not replace breast milk or infant formula as the main drink before age 1.

Avoid herbal laxative teas, detox drinks and unprescribed laxative products for children. Natural products are not necessarily safe for a child's age, and some can cause diarrhea or dehydration. Do not stop a prescribed medicine or change its dose without speaking to the prescriber.

How much can a child safely drink?

These are general daily beverage guides, not amounts to force a child to drink as a constipation treatment. Needs vary with activity, weather and health, and a clinician may give different instructions for a child with a medical condition or fluid restriction.

Age	General daily drink guidance
Under 6 months	Breast milk or properly prepared infant formula; give extra water only if a clinician advises it.
6–12 months	Breast milk or formula remains the main drink. Around 4–8 fluid ounces (120–240 mL) of water may be offered daily once solid foods begin.
1–3 years	About 4 cups (960 mL) of beverages a day, including water or milk.
4–8 years	About 5 cups (1.2 L) of beverages a day, including water or milk.
Older children	About 7–8 cups (1.7–1.9 L) of beverages a day, with individual needs varying.

For children age 1 and older, the following are daily maximums for 100% fruit juice, not recommended constipation doses. A smaller serving may be sufficient, and juice is not required.

Age	Maximum juice per day
Under 12 months	No juice unless specifically recommended by the child's clinician.
1–3 years	4 fluid ounces (120 mL).
4–6 years	4–6 fluid ounces (120–180 mL).
7–18 years	8 fluid ounces (240 mL).

Count all juice a child drinks during the day toward the limit, including juice served at school or mixed with water. Diluting juice increases the volume of the drink but does not change how much juice it contains.

If juice causes diarrhea or cramps, stop offering it for constipation and ask a clinician for advice if symptoms continue. Do not compensate by pushing large amounts of water: excessive fluid intake can also be harmful.

When should you talk to your child's doctor?

Contact a clinician promptly if you suspect constipation in a baby under 1 year, or if an older child has ongoing pain, repeatedly holds stool, has blood with a bowel movement, or is not improving. Constipation can involve hard, dry or painful stools; how often a child passes stool is not the only consideration.

Seek urgent medical care if a child has severe or worsening abdominal pain, a swollen abdomen with vomiting, green vomit, substantial bleeding, or is unusually drowsy or difficult to wake. These signs need assessment rather than a trial of drinks at home.

Also ask for medical advice if constipation keeps returning, lasts more than 2 weeks, or is accompanied by poor appetite, weight loss or stool leakage. A clinician can advise whether a toilet routine, a medication or another assessment is appropriate. If a child has kidney disease, another condition requiring fluid limits, or takes medicine that may affect bowel movements, ask their care team before changing their drinking plan.
