Diarrhea in Infants

It is not advisable to add anything into formula. Your baby doesn't need it, and as you've seen, it can cause diarrhea or other problems.

Be sure to mix the formula according to the package directions.

If your baby's diarrhea continues for more than a couple of days after you stop adding anything to the formula, or if he develops fever, vomiting, crankiness, decreased urination or any other symptoms, call your doctor.
