sounds viral.. just keep doing the breastmilk.. and warm washcloth to get the crud off in the am. I used to get it really bad as a child.. and my mom would have to come get me a warm cloth and let my eyes soak so i could peel em and open em in the morning. If shes not bothered i'd let it run its course especially since it sounds like she has a cold. Is her nose congested as well? your ears, eyes and nose are all linked together so she may get some pressure in her ears and sinuses. again.. warm compresses but you may have to sneak em in during nap time or warm showers and play a game where she puts her face in the water.
