So I got a nasty beat infection in my left breast. Started antibiotics 3 days ago, now I have an infection in my right and my supply is so low. I'm pumping every 3 hours and can only get an ounce each time out of that breast 2 -3 on the left now that the infection seems to have left that side. The problem is, Bubba is eating 3oz every 2-3.5 hours leaving no extra milk for him. Did anyone else experience multiple infections? How did u treat, and how was your supply? I'm worried that this antibiotic isn't strong enough. What causes them?
