Baby with E. coli

My daughter had gotten E. coli. We took her to the doc and basically they said E. coli is something they body gets over on it’s own, but he did give meds to speed up the process. She took medication once a day for 5 days which was over a week ago. She’s still having horrible runny poops and it may be a little more mushy but it’s still not good.

Has anyone else had a baby with E. coli? How long did it take for them to get over it?

Thanks!😊
