My infant has yellowish eye discharges since birth. Is it normal and what can I do to it?

Not normal. Could be blocked tear duct. Try massage gently tear duct at the corner of inner eye. If not working need probing to clear tear duct See pediatric opthalmologist.
Depends. What you describe may indicate a condition called nasolacrimal duct obstruction (nldo). It is fairly common in infants, and usually resolves spontaneously; however, it sometimes requires probing to open the ducts. I would recommend having your infant seen by a pediatric ophthalmologist to be certain.
Seek eval. This can also be a sign of abnormal or borderline abnormal nasal anatomy also.
Yellow eye discharge. The discharge may be due to Erythromycin applied to the babys eyes when first born to prevent possible gonorrhea.
