I'm a "blurter" and never got too embarrassed about it, accepted both me's (and fortunately they were both in the same body :-) so whoever's comments showed up. Sometimes I was the adult conversing with the T about the child with the child in the room and occasionally commenting; sometimes I'd deliberately encourage the child and other times I'd work with the adult taking care of the child and getting "practice" so I could take over from the T. But the feelings are the same/all one? If you child doesn't want to leave the T then you know you like the T both child and adult? There's nothing "childish" about enjoying being with someone and letting them know! That's part of the whole purpose of therapy.
