Don't treat infant constipation with corn syrup.
Dark corn syrup was once a common home remedy for infant constipation. However, today's commercially prepared dark corn syrup might not contain the type of chemical structure that draws fluid into the intestine and softens stool. This makes dark corn syrup ineffective for infant constipation.
If your newborn seems constipated, contact his or her doctor for advice. If your older baby seems constipated, you might consider simple dietary changes or, occasionally, an infant glycerin suppository.
