S.B.
My recommendation is to sterilize everything possible. It is a fecal-mouth transmission, so anything that might possibly have fecal particles on it can give it to you again. Our daughter was doing projectile poop, we'd open her diaper and it would shoot across the room, so her room was getting super sterilized as a result. Hand washing is super important and the BRAT diet was also helpful. Bananas, Rice, Applesauce and Toast. Our DD hates rice cereal so our Dr. recommended yogurt instead. That helped also. Good luck!
Also, if you're formula feeding, Similac makes a liquid form called Similac A-D which is anti-diarrheal. We found some at Walgreens. Our daughter didnt want to drink it though, since it was so much thicker than her regular, powder formula, but our Dr. recommended trying it.
