In this reflection image, my son is looking right at me. That's something he never does. Somehow, the barrier of the glass wall let him see me. I often sometimes think wistfully about this version of him, the one behind the glass. I love him the way he is, but I'd give anything to embrace the boy behind the barrier.

One of the core characteristics of autism is differences in sensory processing. The world can be overwhelming with so many sounds and sights and smells. But this can be a gift too; my son experiences the world in a way I never will.

I often feel like there is something separating my son and me. We can see and hear each other through this barrier, but we can't quite touch. Here, I photographed him through a sheet of ice to symbolize that experience.

One of my son's great gifts is his ability to focus completely on something. A puzzle, a musical instrument, the way the light makes colors in the clouds... He can put all of himself into what he loves, and I try to do the same in my interactions with him.

Photographing someone with autism isn't always easy, but that's because a good portrait is about emotional connection. To connect with someone on the spectrum, it helps to enter his world. Here, he's pretending to be an owl, and owls are his current area of special interest.

Some days are very, very hard. On off days, I start the morning with my son yelling that he hates me. The truth is, sometimes I drop him off at school and try not to squeal my tires as I drive away. I feel like a failure as a mother on those days, but I also know that those are the days that prove my love for him.

My son and I have a solid but very dramatic relationship. I make him really angry with my efforts to get him to school on time or have him eat something different for dinner. But I'm there for him, even when we're mad at each other. I think, I hope, he knows that.
