I'm sorry to hear this.. I know that once you have had mastitis in one spot, it's more likely to recur as the duct often has some stretching or scarring that can make a blockage more likely. Some women (very rarely, luckily) are prone to mastitis.. I don't think it's fair to think that it's all just bad management. It sounds like you're doing lots of good things already. Have you heard of the tactics like feeding in different positions, positioning the baby's nose towards the blockage, etc to dry and ensure good milk drainage? Do you tend to feed in different positions?

Hopefully you can get through the next month or so and then it will be smooth sailing, engorgement does settle down and you'll be less likely to have milk pooling in the breasts. It's tough dealing with mastitis with a small baby! You're doing a great job.

eta out of curiousity - what are your symptoms? is it soreness and heat on the breast, or is it the fullblown fever, fatigue, aches etc?
