Dear Help her get some exercise. If your baby's a crawler, encourage her to do a few laps. If she's not crawling yet, try pumping her legs instead. While she's lying on her back, gently move her legs in a forward, circular motion as if she were pedaling a bicycle.
Massage your baby's belly. Measure three finger-widths below her navel on the lower left side and apply gentle but firm pressure there with your fingertips. Press until you feel a firmness or mass. Maintain gentle but constant pressure for about three minutes.
If you feed your baby formula, ask her doctor about switching to a different brand. Sometimes adding dark corn syrup to the formula also does the trick: Start with 1/4 teaspoon per 4 ounces of formula. If that doesn't help, gradually increase the amount. Don't give her more than 1 teaspoon per 4 ounces.
Add a little prune juice to formula or breast milk if your baby is at least 4 weeks old. Normally, it isn't necessary to give your baby juice, but a little is okay to help relieve constipation. (Try apple or pear juice if your baby doesn't like the taste of prunes.) Give her an ounce a day for each month of life, up to 4 ounces for a 4-month-old. After 8 months, your baby can have as much as 6 ounces of juice a day to treat constipation.
If your baby is old enough to eat a variety of solid foods, cut down on constipating foods like rice, bananas, and cooked carrots. Try giving her a few tablespoons of pureed prunes, apricots, or pears to help loosen her bowel movements. For the best result, give your baby a belly massage first, then some high fiber food.
