The thermometer trick usually worked well for Myles.
Maybe some benefiber if that doesn’t work. I’ve found it to be very helpful for Myles with no side effects whatsoever. It’s just fiber, so maybe it would be ok for her. I really don’t know anthing about entercolitis, though.
Usually antibiotics cause loose stools, so I don’t think it would be from the antibiotic, but anything’s possible and our babies are all so different. Did she have loose stools on Zegerid? Maybe her body needs time to adjust to not having the Zegerid anymore. Sorry, I’m not being very helpful.
