i don't think there is anything wrong with it, but i'd encourage you to let all your Ts know that you are consulting other people. if they have a problem with it, then that's their problem, not yours. but it would be useful for them to know each other's details, in case they want to consult someone on it. e.g. my T and my pdoc work over the same sort of things, but i find their different styles helpful. but sometimes when i am in crisis, it's useful for them to check in with each other and devise a plan together. i don't think they've spoken to each other about me often - maybe 2-3 times and i've been seeing them for 2 years.
