My t told me she doesn't hold any clients in her practice, but she will offer a hug or hand hold at times if it is needed.

In reading the above information about nurturing touch, I noticed this paragraph:

The healing environment of Protective Nurture is as much "a feeling in the air" - psychic containment, if you will - as it is a physical one. The therapist exuding this level of protection does not always have to touch or hold a client in order for the healing to work. In fact, most of the work will take place without any kind of touch, with the client deep into their feelings, being respectfully contained, witnessed and lovingly acknowledged by the therapist. Touching and holding (even hand holding or hand-on -shoulder), however, is simply a necessary human communication, and will happen at certain points when a human "contacts" and is really with another human being.
It sounds like much of the "holding" is an emotional holding that is present through the t's compassionate presence with the client. Maybe the physical touch is only used in a limited way.
