[cypher]

It's quite likely that being handles a bit roughly by a child has scared her & made her a bit nervous, they do get less active in the winter months though so it could possibly be that, make sure the room is warm enough at all times & that she has lots of shredded tissue to make a nice big cosy nest.
I would just keep coaxing her out for short periods, reassure her & give her some time, if she has lost her confidence she should come round again with a bit of TLC.
