But now the nearly full prescription bottle was sealed in clear plastic on a metal counter.

For once, I didn’t defend myself.

“Please write down exactly what my daughter said,” I told Dr. Sterling. “And I don’t want either of them answering questions for me.”

My husband stared at me.

“I’m his father.”

“Then answer one question,” I said. “Did you know your mother was replacing his medicine?”

He looked toward the door instead of at our son.

My mother-in-law crossed her arms.

“We did what was necessary because you were making that baby nervous. Children can feel panic.”

The nurse came back with the medication bag.

Dr. Sterling placed the amber bottle inside, sealed it, wrote the time on the label, and set it beside the chart.

Then he asked my daughter when she had first seen the medicine switched.

She looked down at the teddy bear in her lap.

“The first night Grandma stayed over.”

My husband shook his head.

“She dreamed that.”

My daughter’s chin lifted.

“No. I came downstairs because the baby was crying. Grandma was holding the syringe, and Daddy told me to go back to bed.”

My heartbeat seemed louder than every machine in the room.

“Did it happen more than once?” I asked.

She counted silently against the bear’s paw.

“Three nights,” she said. “Grandma did it every night after you fell asleep.”

My mother-in-law started talking about children’s imaginations again.

My daughter finally raised her face and looked directly at her father.

“Daddy held the baby while she did it.”

My husband opened his mouth, but Dr. Sterling raised one hand.

“I need one person speaking at a time.”

That was the first moment since we’d entered the office that someone stopped my husband from explaining me.

The nurse took my son from my arms only long enough to begin the care Dr. Sterling had ordered, and I stayed close enough to touch his foot.

My daughter stood beside me with the teddy bear pressed under one arm.

My husband remained near the wall.

His mother kept whispering to him.

Dr. Sterling asked him a simple question.

“Were you present on those three nights?”

My husband said, “I was home.”

“That wasn’t the question.”

My husband rubbed both hands over his face.

“I was there some of the time.”

My daughter spoke before anyone could stop her.

“All three times.”

His mother snapped her name.

My daughter flinched.

I moved between them.

It happened without planning.

One second I was standing beside my son’s bed, and the next my body had turned toward my daughter, putting my shoulder between her and the two adults who had spent the last ten minutes telling everyone she couldn’t trust what she’d seen.
