Q: Teary eyes: cause for concern?
A: Your son has a blocked tear duct. The first line of therapy is to massage the duct five to 10 times each day (use your little finger to gently stroke the inside corner of the eye, right next to the nose, using a circular motion). You'll also need to flush the eye several times a day. If possible, use expressed breast milk, as it contains antibodies to ward off infection. You also can use saline solution (make sure it has no thimerosal, a mercury-based preservative). If infection does set in--usually characterized by a red or swollen lower eyelid--call your pediatrician. Also call if the discharge seems excessive or if your baby seems very sensitive to light.
