10 mo has slimy green poo

For the past couple of days my 10 mo has had diarrhea. Green and pasty. Today it was watery and slimy and there were whole beans in it (her breakfast from yesterday) I called the pediatrician and they said try pedialite but its not helping. She has no fever and she is breastfed as well. Is this normal??? Or what can I give her that'll help?
