The best first step for a constipated toddler is increasing fiber, fluids, and specific fruits and juices before reaching for any medication. Most toddler constipation responds well to dietary changes alone, and when it doesn’t, a few safe over-the-counter options can help. Here’s what works and how much to give.
How to Tell if Your Toddler Is Actually Constipated
Constipation in toddlers isn’t just about how often they poop. Some healthy toddlers go once every two or three days. What matters more is the consistency and whether it’s causing discomfort. Hard, pellet-like stools, straining that lasts more than 10 minutes, pain during bowel movements, or streaks of blood on the stool from small tears are the real signs. If your toddler is passing soft stools every couple of days without fuss, that’s likely normal.
Toddlers are especially prone to constipation during potty training, after switching from breast milk or formula to cow’s milk, and when they start refusing vegetables. A toddler who had one painful poop may start holding it in to avoid the pain, which creates a cycle where stool builds up, hardens further, and becomes even more uncomfortable to pass.
High-Fiber Foods That Help
Toddlers between 1 and 3 years old need about 19 grams of fiber per day, according to Cleveland Clinic guidelines. Most toddlers fall well short of that. Closing the gap is one of the most effective ways to get things moving.
The best fiber sources for toddlers are ones they’ll actually eat. Pears, prunes, peaches, and plums (sometimes called the “P fruits”) are especially helpful because they contain sorbitol, a natural sugar alcohol that draws water into the intestines and softens stool. Berries, beans, peas, oatmeal, whole wheat bread, and sweet potatoes are also high in fiber and toddler-friendly. Even small additions count: swapping white bread for whole grain or adding a handful of raspberries to a snack adds several grams of fiber.
Increase fiber gradually over a few days rather than all at once. A sudden jump can cause gas and bloating, which won’t make your toddler any more enthusiastic about eating these foods.
Juices That Work as Natural Laxatives
For toddlers 1 year and older, Children’s Hospital of Philadelphia recommends increasing water and juice intake to relieve constipation. Prune juice, pear juice, and apple juice are the go-to options because they contain sorbitol. Prune juice is the most potent of the three.
Start with 2 to 4 ounces of juice per day and see how your toddler responds. You can dilute it with equal parts water if the taste is too strong or if it causes loose stools. Juice works relatively quickly, often within a few hours to a day, and it’s a good option when you need relief sooner than dietary fiber alone can provide.
How Much Water Your Toddler Needs
Fiber without enough fluid can actually make constipation worse, because fiber absorbs water as it moves through the gut. If there isn’t enough water available, stools become drier and harder to pass.
The American Academy of Pediatrics recommends 1 to 4 cups of water per day for toddlers aged 12 to 24 months, and 1 to 5 cups per day for children 2 to 5. Milk counts toward total fluid intake, but too much cow’s milk is a common constipation culprit. Keep whole milk to about 2 cups per day for toddlers under 2, and 2 to 3 cups of low-fat milk for kids over 2. If your toddler is drinking significantly more milk than that, cutting back and replacing some of it with water often helps on its own.
Over-the-Counter Options
When diet changes aren’t enough, a few OTC products are considered safe for toddlers, but all of them come with a caveat: check with your pediatrician before using them, especially for children under 2.
Polyethylene Glycol (MiraLAX)
This is the most commonly recommended stool softener for young children. It works by pulling water into the colon to soften stool. The Mayo Clinic notes that dosing for children under 17 should be determined by a doctor, and the product shouldn’t be used for more than 7 days without medical guidance. Your pediatrician will typically recommend a small dose mixed into water or juice. If constipation hasn’t improved within a week, that’s a sign to call your doctor rather than continue on your own.
Milk of Magnesia
Magnesium hydroxide is another option that draws water into the intestines. For children 2 to under 6, the labeled starting dose for chewable tablets is 1 to 3 tablets per day, with a maximum of 3. For children under 2, the label directs you to ask a doctor first. It should always be given with a full glass of liquid.
Glycerin Suppositories
These are sometimes used for more immediate relief when a toddler is visibly struggling and uncomfortable. They work within minutes by lubricating the rectum and stimulating a bowel movement. They’re meant for occasional use, not as a regular solution.
Do Probiotics Help?
The evidence on probiotics for toddler constipation is mixed but leaning positive. A systematic review of clinical trials found that probiotics significantly improved how often children had bowel movements compared to a placebo. However, the same review noted that the effects depend heavily on which specific bacterial strain is used, and researchers haven’t yet pinpointed the best strains, doses, or treatment durations for children. Probiotics are unlikely to cause harm, but they shouldn’t be your primary strategy. Think of them as a possible supplement to dietary changes, not a replacement.
Movement and Toilet Habits
Physical activity stimulates the muscles in the abdomen and helps move food through the digestive tract. Toddlers who spend long stretches sitting, especially after meals, are more likely to feel sluggish and uncomfortable. Active play after eating, even just running around or climbing at a playground, supports healthy digestion.
Toilet habits matter too, particularly for toddlers in the middle of potty training. If your child is holding stool in, try having them sit on the toilet for a few minutes after meals, when the body’s natural digestive reflexes are strongest. Keep it low-pressure. A small step stool that lets their feet rest flat (so their knees are slightly above their hips) puts them in a better position to go. Forcing the issue or showing frustration tends to backfire and makes withholding worse.
Foods That Can Make It Worse
A few common toddler staples are binding and can contribute to constipation. Bananas (especially unripe ones), white rice, white bread, cheese, and large amounts of cow’s milk are frequent offenders. You don’t need to eliminate these entirely, but if your toddler is constipated and eating a lot of them, scaling back while increasing fiber and fluids can make a noticeable difference. Processed snack foods like crackers and cookies are also low in fiber and can crowd out the fruits, vegetables, and whole grains that keep things moving.
