Key takeaways
- Prune juice is one of the most effective natural remedies for baby constipation. For babies 4 months and older, offer 1 to 2 ounces of 100% prune juice (no added sugar) once or twice daily.

“The biggest concern with vomiting is dehydration. Young children can become dehydrated quickly, so it's important to replace fluids. Offer small amounts of an oral rehydration solution frequently.”
Parents everywhere have the same worry. You are doing the right thing by looking into it.
What Parents Should Know
According to AAP, NIDDK guidelines, prune juice is one of the most effective natural remedies for baby constipation. For babies 4 months and older, offer 1 to 2 ounces of 100% prune juice (no added sugar) once or twice daily. You can dilute it with an equal amount of water. For babies 6 months and older, pureed prunes are equally effective and provide additional fiber. Always choose 100% juice without added sugars. At 0-3 months, prune juice is generally not recommended before 4 months of age. If your young infant is constipated, discuss with your pediatrician before offering any juice. Breastfed babies rarely need prune juice as breast milk acts as a natural laxative. It is generally considered normal when softer stools within 12 to 24 hours of starting prune juice. However, you should contact your pediatrician promptly if severe abdominal distension with vomiting in a constipated baby despite trying prune juice.
Normal vs. Concerning
By Age
What to expect by age
0-3 months
Prune juice is generally not recommended before 4 months of age. If your young infant is constipated, discuss with your pediatrician before offering any juice. Breastfed babies rarely need prune juice as breast milk acts as a natural laxative.
3-6 months
Starting around 4 months (with pediatrician approval), you can offer 1 ounce of 100% prune juice mixed with 1 ounce of water once or twice daily for constipation. Offer it in a bottle or small cup. If constipation resolves, you can stop the juice.
6-12 months
Pureed prunes can be offered as a solid food, which provides both the natural laxative effect and fiber. Two to four tablespoons of prune puree daily can help keep stools soft. You can mix prunes into cereal or other foods. Continue offering prune juice as needed.
12-24 months
Toddlers can eat whole soft prunes, drink prune juice (up to 4 ounces daily), or have prune puree mixed into foods. Making prunes a regular part of the diet helps prevent constipation. Limit total juice intake to 4 ounces per day as recommended by the AAP.

Related Conditions
Baby Constipation
Constipation in babies is defined by hard, dry, difficult-to-pass stools rather than by how often your baby poops. Breastfed babies can go several days without a bowel movement and still be perfectly normal. If your baby is passing soft stools comfortably, even if infrequently, they are likely not constipated.
Safe Constipation Remedies for Baby
Safe constipation remedies for babies include tummy massage, bicycle legs, warm baths, and for babies over 4 months, offering small amounts of 100% prune, pear, or apple juice (1 to 2 ounces). High-fiber foods like prunes, pears, and peas help once solids are started. Never give laxatives, suppositories, or enemas without your pediatrician's guidance. Avoid honey, corn syrup, and mineral oil in babies under 1 year.
Constipation After Starting Solid Foods
Constipation when starting solids is very common because your baby's digestive system is adjusting to processing new types of food. Low-fiber first foods like rice cereal, bananas, and applesauce are common culprits. Balancing with high-fiber foods like prunes, pears, peas, and oatmeal, and offering water between meals, usually resolves it.

My Baby's Belly Looks Swollen
A rounded, slightly protruding belly is completely normal in babies and toddlers due to immature abdominal muscles and their proportionally larger organs. However, if the belly becomes suddenly swollen, feels hard and tight, or is accompanied by pain, vomiting, or changes in bowel movements, it needs medical evaluation as it could signal gas buildup, constipation, or rarely, something more serious.
My Baby Has an Anal Fissure (Blood When Pooping)
A small streak of bright red blood on the surface of your baby's stool or on the diaper is most commonly caused by an anal fissure, which is a tiny tear in the skin around the anus from passing hard stool. Anal fissures are very common in babies and toddlers and usually heal on their own with simple measures like keeping stools soft. While this is rarely serious, any blood in your baby's stool should be mentioned to your pediatrician.
Can Antibiotics Damage My Baby's Gut?
Antibiotics can temporarily disrupt your baby's gut microbiome, which may cause loose stools, fussiness, or diaper rash during and shortly after treatment. However, when antibiotics are medically necessary, the benefits of treating the infection far outweigh the temporary gut disruption. Most babies' microbiomes recover within weeks to months, especially with breastfeeding and a gradual return to normal feeding patterns.
