Hi Hals,
Same with me...this is my second Christmas with my T, too. Also the same, that last year I didn't even consider it, but this year I definitely want to get her something.
It doesn't sound like your T has a strict "no gift" policy or else you wouldn't even be considering it. My T has never stated anything either...but last year around this time, when I came in for my session, there was a little gift bag sitting on the floor by her chair...she had gone to the restroom and told me to go right in, but I think she forgot about the bag...at first I panicked thinking maybe it was for me, and I hadn't gotten her anything...but then when she came back, she kind of nonchalantly moved it out of my sight...so it must have been a Christmas gift from another patient. So anyway, from that, I assumed that she accepts gifts. Earlier this year, I gave her a begonia, and it went well, so I'm pretty sure a Christmas gift would go well, too.
So I would hope that your T would be gracious in accepting your gift, whatever it turns out to be.
The other thing about gifts, in this therapeutic relationship, is that your T is probably going to want to talk about what the gift "means" about you or to you.
My T she has mentioned a few times what my gift-giving says about me, especially lately, when we discuss self-esteem issues. She has pointed out that it says I'm very thoughtful, that I pay attention to the details about people...for example, I got her a begonia because she had told me that her apartment faces away from the sun, and had also asked me if I knew of any shade-loving flowers, and the color was the same color as a vase of fake gerbera daisies in her office (I didn't get the daisies because those are sun-lovers). So I would hope that your T would also take your gift-giving as an opportunity for you to learn more about you.
So my feeling about it is, if you really want to get your T a gift, then go for it.
If you are worried about whether it will affect your relationship, maybe you could ask him ahead of time if it's okay? If nothing else maybe you could just talk about what it says about you, that you are so concerned about it, wanting to get just the right gift...my guess is that at least part of this is that you are a very thoughtful and generous and caring person...and maybe you need to hear that a few times.
Good luck, Hals...let us know how it goes!
