What to do when baby is constipated?

Here are some things to try: 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.
