Reoccuring pink eye

Danielle
Hey ladies. I've got an issue. My little guy has pink eye for the 3rd time in just as many months. The first was from me, I caught it in the hospital after having him, but these last two have come on so suddenly, and none of us have caught it too. We saw his doctor about it the second time and he gave us refills on the antibiotics, and they've worked everytime, so I know it's bacterial. I'm just concerned because it frickin hurts. The poor kid is so cranky and won't stop rubbing his eyes. I'm going to be seeing his doctor again this week but do you have any other suggestions?
