My ds is 4 weeks tomorrow and on Friday I developed mastitis, which I'm treating with antibiotics and feeding/expressing. Yesterday and again today ds has cried to be fed every hour, he usually goes 2 to3 hours, and is feeding for up to 40 minutes each time! It's relentless! Could the mastitis or antibiotics be affecting my supply in any way? I'm concerned he is feeding so much because he isn't getting what he needs.
