My child's eyes often got excessive tear. Do you know the reason of being it? Is it because of blocking nose? is it because of eye problem? polyclinic doctor says it could b bcos of blocking nose. but i suspect it could b bcos of eye problem. Should l approach child's hospital directly? or should i approach polyclinic again to get referee letter. Any suggestion?? btw, my baby is 3 years old +. Should she wear eyeglass?
