Yes, breast milk is often recommended as treatment for babies, who are suffering from blocked tear duct. Usually babies get blocked tear duct for congenital reason, which means they are born with it. The duct for tear draining from eyes to nose is not fully developed at birth or the membrane between the inner corner of eye and nose does not break or dissolve. With blocked tear duct, your baby might have watering eyes. What is worse is the infection might be built up in the inner corner of its eyes. Generally speaking, it could be very disappointing and worrying. Every parent would like to see the baby happy, beautiful and healthy. Yet because of the infections from blocked tear duct, your baby's eyes are not just watering, they are full of icky green pus. Many pediatricians would recommend the mothers to drop breast milk into baby's eyes, which could effectively control the infection of eyes. The discharge would be far better, although it doesn't help unblock the tear duct, yet it is much better than using antibiotic for a baby. And don't worry too much, because almost 80% of babies with blocked tear duct can outgrow the blockage.
