Any advice would be a huge help. I got mastitis around may 29th. Started antibiotics the 31st and they ended on June 7th. Yesterday the 10th I started showing signs of mastitis again in the same breast, in the same spot and started another antibiotic today. I can't figure out why I got mastitis again. My baby is almost 4 weeks old. She's got a good latch. I feed her on demand. Some days it feels like she never stops eating. If she doesn't empty my breasts I try to pump after she eats. That doesn't always happen though.
