It was like living with a bull in a china shop. One day he broke all the eggs in the kitchen in order to hear how they would sound (I was on the phone). The next afternoon, he smashed every bottle of perfume I owned against the tile floor, to see how far the glass would shatter (I was in the downstairs lavette). I caught him climbing the china cabinet one afternoon, and wisely padlocked the doors (I’d been in the shower, but realized I couldn’t hear Evan and went bolting through the house in nothing but a towel).

We saw our first expert, a child development specialist. We received our first diagnosis. Evan suffered from global Sensory Integration Disorder; his brain was properly receiving input from his five senses, but could not prioritize the sensations. Meaning he existed in an overstimulated state—a full cup, the specialist explained to us, where each new sound, scent, touch, smell, and taste was another drip, drip, drip into an overflowing vessel. Some things he could not tolerate at all: the rasp of a zipper, the feel of denim. Other sensations he fixated on, trying to get them to penetrate the clutter of his brain—what is sharp, what is hot, what is pain. He was like a moth, drawn to the flame.

Evan started to receive occupational therapy. Michael agreed that I needed help, so we hired our first in a string of what would become fourteen part-time nannies.

I went on walks to clear my head and refresh my body. Then I came home to my crazy, exuberant wild child. He would bowl me over with his hugs. Light up the world with the exuberance of his laughter. We would wrestle, tickle, and play endless games of hide-and-seek.

Then he would scream over having to brush his teeth. Or fly into a rage over having been served pasta on the wrong-colored plate. He threw one of Michael’s golf balls through our family room window when we asked him to put on shoes. He slapped me across the face when I told him it was time for bed.

Our first nanny quit, then the second, the third.

When Evan was happy, he was so happy. But when he was angry, he was so angry, and when he was sad … he was so, so sad.

We received our second diagnosis: Mood Disorder NOS (Not Otherwise Specified). At four, we put him on clonidine, a drug generally used with ADHD to help moderate impulsive and oppositional behavior. We hoped the clonidine would take off the edge, allowing Evan to find some measure of self-control.

He improved in the short term. Slept better at night. Less manic during the day. Between the clonidine and a one-to-one aide, it appeared he might survive preschool.
