Maybe your T is making sure that she (he? I'm not sure if your therapist is male or female) is giving physical contact to the adult you. We strive to have our adult parts be the ones in control-- and, of course, adults need comfort, too. In my opinion, it is not a good idea for a therapist to hug someone when they are in "little kid" mode. A therapist is a therapist-- not a parent. And when we feel like little kids in therapy, we normally want some type of parental comfort-- we are not aware, or looking for, that adult connection. Perhaps your T is striving to connect to that adult part. I bet that unconsciously your adult needs (and deserves) connection and comfort, too.
