Getting to know who we are on the inside can be enlightening! Here are some suggestions if you want to try any of them. They are things I have done to facilitate my own internal communication:

1) Mirror Work - Stand calmly infront of a mirror and just look into your own eyes. Open your heart and honestly ask that part of you to introduce itself or come forward. Then watch in the mirror as that part responds. If is odd at first because you will see your own response as well and the switching between the states is not very fluid. But with time, the ability to communicate with that part of yourself through the mirror will become very easy.

2) With younger parts, it is good to have some type of art supplies around - if that part is old enough to hold a crayon or such. If not, try to use clay or playdo. For the very young ones, I would think fingerpaints might be fine.

3) Record an audio session with yourself and the parts. This can be done for older alters as an interview. Or when you feel the part start to come forward, you can click on the recording device - or now a days we can use cell phone memo feature - and capture the dialog.
