My 20 week old girl once had an infection in her eye and she got rid of it by me putting salt water in her eye. Then she was fine just blind out of that one eye but she could eat and drink and do everything on her own fine. Now say 3 to 4 weeks down the road she has another infection in her same eye! And I have been putting warm salt water in her eye again. Is there anything else I could do for her? And why does she keep getting infections i her eye?
