My six-year-old daughter and I were changing the diaper of my sister’s newborn baby when my daughter pointed at her little cousin and said, “Mom, what’s that?”

That morning, my sister had called me early. She had just become a mother, was exhausted, sleep-deprived, and asked me for a favor — to watch the baby for a couple of hours so she could get some rest.

Of course, I agreed. My daughter and I adored that little one.

My six-year-old was over the moon — she rocked her cousin gently, stroked her tiny head, and sang lullabies.

Everything was calm and peaceful: a quiet day, soft laughter, the scent of milk and clean diapers.

But after a few hours, the baby woke up and began to cry loudly. I realized it was time to change her diaper.

My daughter eagerly offered to help — she always wants to feel “grown up,” especially when there’s a baby around.

I laid a clean cloth on the bed, gently placed the baby on it, and opened the diaper.

At that moment, my daughter frowned, froze, and softly asked, pointing at her cousin:

— Mom… what’s that?

I looked where she was pointing — and felt my blood run cold  Continued in the first comment 

On the baby’s tummy and legs were bluish-purple marks. It looked as if someone had squeezed or hit her.

I froze in shock.

— Sweetheart… did you do this? — I asked in a trembling voice.

— No, Mommy, I just kissed her, — she answered, her voice shaking, almost crying.

A chill ran down my spine. I immediately called my sister. When she answered, I told her what I had found.
She was silent for a long time, then said, in an eerily calm voice:

— It was me…

At first, I didn’t understand.

— What do you mean, you?

— I did it… I just couldn’t take it anymore. She cried all night. I didn’t sleep, I didn’t eat… I didn’t mean to, I just lost control.

I sat in silence, not knowing what to say. My chest tightened with fear and pain. In my mind, I could see her tired, broken smile.

And I understood — my sister wasn’t a monster. She was just burned out, lost, and no one had noticed in time how badly she was struggling.

Since that day, I’ve been visiting her almost every day. I take the baby with me so she can sleep, take a walk, or simply feel human again — not just a constantly anxious, exhausted mother.

Sometimes I think back to that day and realize how close she was to the edge. And how important it is to have someone nearby — someone who offers a shoulder at just the right moment.
