For eighteen years, I convinced myself that keeping my daughter’s twin sister a secret was an act of love.

I told myself I was protecting her.

Then, on her eighteenth birthday, my husband placed a wooden box in front of her and forced me to face something I had spent nearly two decades avoiding.

Our daughter Hannah had been born with a twin.

Her name was Rosie.

And Hannah had never known she existed.

Rosie was eleven minutes younger.

She weighed six pounds, one ounce, and had dark hair.

There was a tiny crease beside her left eye that appeared whenever she cried.

Hannah had always been the louder baby.

Rosie was quieter.

I used to joke that Hannah cried enough for both of them.

Then Rosie died.

She was only nine days old.

The official cause was SIDS.

Sudden Infant Death Syndrome.

There was no warning.
