I wish more than anything that I had been wrong — that all my worry was just anxiety and stress playing tricks on me. But I wasn’t. And I would give anything to go back and be mistaken.

My name is Martha, and I’m the mother of a four-year-old girl named Beverly.

My husband Jason and I both work full-time, so during the week, Beverly usually goes to daycare. It’s not ideal — the mom guilt is always there — but she seemed happy, made friends, and was thriving.

“She’s doing fine, Martha,” Jason reassured me one morning as we packed her lunch.

“I know,” I replied, “I just don’t want her to ever feel like we’re too busy for her.”

A few weeks ago, Jason’s mom, Cheryl, made what sounded like a generous offer.

“Why don’t I take care of Beverly on Wednesdays?” she said at dinner. “She can take a break from daycare, and we’ll have some grandma time. It’ll be good for her.”

I was hesitant. Cheryl and I never had the closest relationship — there was always a hint of judgment in her tone, even when she tried to be nice. Still, she seemed genuine, and it would give Beverly time with family while helping us save a bit on daycare.

So I agreed. And for a while, everything seemed perfectly normal.

But then Beverly started acting… different.

One evening, she refused to eat the dinner I’d cooked and said, “I only want to eat with Daddy, Grandma, and her friend today.”

I froze. “Who’s Grandma’s friend, sweetie?”

She just gave me a strange, secret smile.

At first, I thought she’d invented an imaginary friend. But she kept talking about “Grandma’s friend,” and slowly began to grow more distant from me.

One night, as I tucked her in, she hugged her unicorn plushie and whispered, “Mommy, why don’t you like our friend?”

That stopped me cold.

“Who told you that?”

She hesitated, then said like she was repeating something, “Our friend is family, Mommy. You just don’t see it yet.”

Something felt very wrong.

That weekend, Cheryl joined us for breakfast. While Beverly and Jason flipped pancakes, I casually asked, “Has Bev made any new friends lately? Maybe at the park?”

Cheryl didn’t look up from her coffee.

“Oh, you know how kids are. Always making up stories,” she said too quickly.

My instincts screamed. I didn’t believe her.

That night, I pulled out an old baby monitor camera we had left from Beverly’s infancy — one we’d used briefly during a short trial with a night nanny — and set it up discreetly.

I needed to know the truth.

Wednesday came. I packed Beverly’s snacks and left for work as usual. But by lunchtime, I couldn’t take it anymore. I opened the live feed on my phone.

At first, everything seemed fine. Beverly was playing with dolls. Cheryl was having tea.

Then Cheryl checked her watch and said cheerfully, “Bev, sweetheart, our friend will be here soon!”

My chest tightened.

“Yes, Gran! I love her! Do you think she’ll play with my hair again?”

Her.

“If you ask nicely, I’m sure she will,” Cheryl replied, then added, “And remember, not a word to Mommy.”

Bev nodded solemnly. “Not a word.”
