Girls, hello, can you please tell me what to do with my son who is 1.6 years old? Today evening he started conjunctivitis, his eye itches, pus accumulates in the corner of his eye, he's being fussy, what kind of drops can I put in his eyes? We can only see an ophthalmologist on Monday, we don't have a pediatrician on our site or anyone to consult.
