Tear stains are a tough one. I tried everything from filtered water, changing foods, ruling out allergies, manually trying to clear away the tear stains with Duoxo pads and Desitin treatments. I eventually landed with angel eyes, which has worked wonders on my baby boy. However, it does have an antibiotic, so I would recommend trying everything else first before resorting to this. It's not cheap either.
