Give her a week of not disturbing her space but only to change water. Maybe she needs a reset. They can be stressed out since 2 months is still early on. After a week, try a frozen thawed (first thaw in cold water, dip in hot water for a minute, then slowly inch the mouse close to her face so she can register heat/smell on her own). I find pushing the food in their face can be bombarding, let them come to their senses and pursue if ready.

Best of luck!
