Complete guide on how to prepare and serve diluted prune juice (for constipation) to your baby, by age.
Last reviewed: May 2026
For constipation, offer your 6- to 9-month-old 1-2 ounces (30-60 ml) of the diluted prune juice mixture once or twice a day. Serve it in a bottle or an open cup between regular milk feedings; it should not replace a breastmilk or formula feed. Since prune juice is a source of iron, offering it around the same time as a vitamin C-rich food, like a few spoonfuls of strawberry puree, can aid absorption, though this is less critical than its primary laxative purpose. Encourage self-feeding with an open cup if developmentally appropriate.

For toddlers 9 to 18 months, you can offer 2-4 ounces (60-120 ml) of the diluted prune juice mixture daily to relieve constipation. It's best to serve it in a straw cup or open cup rather than a bottle to protect emerging teeth from prolonged sugar exposure. Offer it between meals so it doesn't interfere with their appetite for nutrient-dense solid foods. Remember that whole, stewed, or pureed prunes are a superior choice as they provide fiber. Pair a meal with healthy fats like avocado to support overall nutrient absorption.

For toddlers over 18 months, a serving of 2-4 ounces (60-120 ml) of diluted prune juice can be used for constipation, but it should not exceed 4 ounces in a 24-hour period. Prioritize serving it in an open cup with a meal, rather than letting them sip it throughout the day, to minimize the risk of dental cavities. At this age, the focus should heavily shift to whole foods. For constipation, a better long-term strategy is offering 2-3 whole, pitted prunes and ensuring they drink plenty of water throughout the day.
