Pears
Constipation is painful for adults so one can only imagine what a little baby must be going through when trying to pass stool. The good thing is natural pear juice can help relieve babies from constipation, according to American Academy of Pediatrics.
An infant should consume 1 ounce of juice per month of age per day. So if a child is a 3-month old, he or she should not have more than 3 ounces of fruit juice per day.
