Breast milk is a very powerful antibacterial substance. I call it miracle juice. It can be used to prevent or mitigate ear infections or eye infections in your baby, not even just your baby, even your older children. I had an experience, when I was nursing my second son, he was congested and I took an eye dropper of breast milk and squirted it up his nose. Over night, his congestion was gone. Another time, my third son was breastfeeding, my older son had an ear infection; so I decided to test the breast milk on him and squirted it in his ear. It was gone the next day. It's a sterile substance and loaded with antibodies. It's the best substance for your children and healthful.
