I have a 5 year old with his tear duct clog ever since he was born he never had one single tear. But he is okay one of his eye doctor said that probley he will never have tears but as long as they are lubricated they are okay and they are but i'm still worried. i still don't know the cause of it, did i do something wrong doring my pregnancy if so someone tell me so I could know so i won't do it in my next pregnancy
