rainbow, i've done inner child work with my T a couple of times and it has been some of the most helpful sessions we've had. she is psychodynamic/psychoanalytic. i think what you are desiring can also be called ego state work like sunny mentioned or inner family systems therapy which is family systems work but with the person's internal family/children. some of the inner child work also comes from a 12-step focus so if you find a T who works with 12-step program issues then they may also do inner child work as i think inner child work originated with them. my T has a 12-step focus as well.
