I'm glad the vet visit checked out - I think the problem may just be that you are keeping too close an eye on this behaviour!!

Try to ignore her every time she begins this - physically turn away from her without speaking to her or looking at her.

She may have YOU very well trained to speak to her every time she wants you to - if this is the case be prepared for the behaviour to get worse before it gets better as she will double her efforts - it has always worked before....why not now???
