Has anyone else had their newborn (mine's 2 months nearly) have a strange reaction to you going on antibiotics? I've got mastitis and he's now really restless and windy (or in pain for some reason) after feeds. No runny bum as promised yet but maybe that's to come. I'm going to try infacol but don't believe that's any good really. Will it all calm down when I finish the course? If so, it's gonna be a long week....
