That's my ambition: that you look at the pictures and realize what complex, fascinating, interesting people every single one of my subjects is.

The images I like best are parts of series that I've started, in some cases, with the pregnancies of the mothers of the children in question, and I continue that series right on through the birth of children to the child that resulted from that first pregnancy.

Every child is going to grow up. You can see it happen in the books: They get older and older and belong to themselves to a greater and greater extent.

I just yesterday returned from a trip where I photographed a woman with two children whom I photographed first when she was the age of the older of the two children.

I've had to relearn how I work with people so that if and when I do avoid different things I don't send any messages in doing so.

When I started doing my work years ago, I had doubts as to whether the informed consent question was answerable.
