Hi Paul..welcome to the forum!
I haven't been on Remicade or prednisone, so don't have the experience. Hope others will chime in on some suggestions.
Is her UC limited or throughout? How long has she had UC?
She could add a fibre supplement to bulk up the stool a bit to help cut down on the # of bms.
How is her diet...does she consume artificial sweeteners? Is she eating at all?..any info can help because sometimes there are food symptoms that can mimic UC symptoms and cause more discomfort than realised.
It's great you're such a supportive son, doing research, etc. Maybe you can encourage your mom to join the forum as well.
