I thought I was simply babysitting while my sister went shopping. But my niece’s cries told me something was wrong. One discovery sent us straight to the hospital.

“I’m here, Paige. Aunt Ally is here,” I repeated, my voice betraying the terror I was trying to suppress.

I pulled beneath the glowing red awning of the ER and demanded a bassinet before I even unlatched her car seat. The triage team moved with the unnerving, hyper-efficient speed reserved for pediatric traumas. They stripped away the green sleeper under the harsh fluorescent lights. Without the diaper obscuring it, the contusion looked monstrous.

The attending pediatric resident examined the swelling with a grim expression. “Did she fall? Roll off a bed? Was there any rough play?”

“No,” I stammered, the sterile lights making me feel momentarily dizzy. “I fed her. I rocked her. I never dropped her. I noticed it when her cry changed after her parents dropped her off.”

The doctor exchanged a loaded, unreadable glance with the head nurse. “We need to get X-rays immediately,” she said, her tone devoid of any comforting bedside manner. “And given the nature of this bruising on a non-mobile infant, I need you to wait right here.”

She stepped out, and I felt the air pressure in the room plummet. I reached for my phone, my fingers flying across the screen to type a frantic text to Kate, telling her to abandon her shopping and get to the hospital immediately. As the “read” receipt popped up, the door swung open again. The doctor re-entered, but she wasn’t alone. She was accompanied by a woman wearing a county badge and a clipboard, her eyes locked directly on me.

“Ms. Ally,” the woman said, her voice smooth but laced with steel. “We have the imaging results. And we have some very serious questions about what happened in your home.”
