It depends on your particular therapist's boundaries.

If you do bring them, you should be prepared for him to not accept them. I would offer them by saying "I'm not sure of your rules about gift giving, so I completely understand if you cannot accept these, but I saw them and thought of you, and I was hoping to give them to you." Again, be fully prepared to hear "I'm sorry, but I can't accept them."

My T has a strict no-gifting policy (except for "things with minimal monetary value" e.g., a card - I imagine a card would be ok...not even sure.)
