I have a 4 month old with conjuntivitus - fully bottle fed. how would i treat it until i take him to the doctor and no chemist is open?

Moist towel: Wiping away the accumulated debris with a moist towel or wet Q-tip can help some. Applying a moist warm compress can increase local blood flow & help their natural healing factors work better. Simple eye drops or artificial tears can help keep the eye moist.

Conjunctivitis : Warm Compresses and cleaning eye with moist cotton can be tried. See doctor.
