For a constipated 5-month-old, the most effective home remedies are small amounts of prune, pear, or apple juice and, if your baby has started solids, high-fiber purees like prunes, peas, and oatmeal cereal. Physical techniques like bicycle legs and belly massage can also help move things along. Most infant constipation resolves with these simple changes within a day or two.
First, Make Sure It’s Actually Constipation
Before trying remedies, it’s worth checking whether your baby is truly constipated or just on a normal schedule. Stool frequency varies widely in infants and depends heavily on how they’re fed. Exclusively breastfed babies typically poop about twice a day between 3 and 12 months, but some go several days between bowel movements and are perfectly healthy. Babies who get formula in addition to breast milk tend to poop less often, sometimes less than once a day, and that alone isn’t a sign of constipation.
What matters more than frequency is consistency. Constipation in infants means hard, dry, pellet-like stools that seem difficult or painful to pass. Your baby may strain, arch their back, cry, or turn red. If the stools are soft, your baby probably isn’t constipated, even if it’s been a few days. Bright red streaks of blood on a hard stool can mean a small tear (fissure) caused by passing that stool, which is uncomfortable but common with constipation.
Fruit Juices That Help
Prune, pear, and apple juice all contain a natural sugar called sorbitol that draws water into the intestines and softens stool. Of the three, prune juice tends to work best. For a 5-month-old, start with about 1 to 2 ounces of 100% fruit juice mixed with an equal amount of water. You can offer this once or twice a day. Because your baby is under 6 months, juice should be used only as a temporary remedy for constipation, not as a regular part of their diet.
A note on water: babies under 6 months who are getting breast milk or formula generally don’t need extra water, and too much can interfere with their nutrition. If your baby is closer to 6 months and already dabbling in solids, small sips of water (a few ounces a day) are fine and can help keep things moving.
High-Fiber Foods if Your Baby Has Started Solids
Many babies begin experimenting with solid foods between 4 and 6 months. If yours has started, certain foods are particularly good at relieving constipation. Children’s Hospital of Philadelphia recommends high-fiber baby cereals like oatmeal, barley, or multigrain (rather than rice cereal, which can be binding). For fruits, prunes are the standout, but pears and apples also help. On the vegetable side, pureed peas and spinach are good options.
A simple approach: offer a tablespoon or two of prune puree once or twice a day, or mix it into cereal. You can also try pureed pears or peas. These foods work because they contain fiber and sorbitol, both of which add bulk and moisture to stool. If your baby hasn’t started solids yet, stick with juice as your primary dietary tool.
Belly Massage and Bicycle Legs
Physical techniques can stimulate your baby’s digestive tract and help trapped gas and stool move through. These are safe to try alongside dietary changes.
- Bicycle legs: Lay your baby on their back and gently move their legs in a cycling motion, as if they’re pedaling a bicycle. You can also gently twist their legs and hips from side to side. This puts light pressure on the abdomen and encourages the digestive system to keep things moving.
- Belly massage: Using gentle pressure, stroke your baby’s belly in a clockwise direction (this follows the path of the large intestine). Start from the lower right side of their belly and move in a half-moon shape to the lower left. You can also use the broad side of your hand to “paddle” gently downward from the rib cage to the lower belly. Do this for a few minutes at a time, especially after feeding or during a diaper change.
- Warm bath: A warm bath can relax the abdominal muscles and sometimes prompt a bowel movement on its own. It also helps if your baby seems uncomfortable or fussy from the constipation.
What Not to Give Your Baby
Some old-fashioned remedies are unsafe for infants. The Mayo Clinic specifically warns against using mineral oil, stimulant laxatives, or enemas on babies. Honey should never be given to any infant under 12 months due to the risk of botulism. Karo syrup, once a popular home remedy, is no longer recommended because modern corn syrup doesn’t have the same stool-softening properties it once did, and it may contain bacterial spores. If diluted juice and high-fiber foods aren’t working, talk to your pediatrician before trying anything else.
Signs That Need Medical Attention
Most infant constipation is functional, meaning there’s no underlying disease causing it. But certain symptoms point to something more serious. Contact your pediatrician if your baby has fever, vomiting, a visibly swollen or hard abdomen, poor weight gain, decreased appetite, or bloody diarrhea. If you’ve tried home remedies for two days with no improvement, or if your baby seems to be in significant pain, that also warrants a call.
Constipation that started in the first month of life, or a baby who had a delayed first bowel movement after birth, can sometimes signal a condition that needs medical evaluation. For the vast majority of 5-month-olds, though, a little prune juice and some belly rubs will get things back on track within a day or two.
