Whether it's allergies or the climate conditions, two of my girls started having yellow like infection in their eyes so instead of going to the Vet. and spending large amounts on office calls and eye drops, I went to Wallgreen's pharmacist and ask him about this and what I can use. He said eye wash since it has an ingredient for infecton. It works beautifully!
I'd suggest you buy a no tear shampoo for your little one.
