Oh no! It didn't even occur to me that I was being an unprofessional employer. I don't want to make her feel uncomfortable. I do email her and tell her a lot in person how much we appreciate and are thankful for her. Maybe I need to tone it down a notch. I am not wanting to be creepy.
It makes sense that you are happy with her, but, yes, honestly, two weeks in is a little early to be obsessed and giving her gifts. I think maybe at three months, if you are still incredibly happy, consider a gift. In the meantime, just show her respect every day. Keep to your agreements, say thank you, be on time. These everyday things show her that you appreciate her.
