PS
You didnt say how old your daughter is???
Some info and images are not, imo, age appropriate for children or young teens ( my grand couldnt handle this)
...so please keep this in mind.
I was always a history geek, even as a young kid. I knew a little of the Holocaust in an oblique way from reading about WW II.
But it wasn’t until watching the TV movie “QB VII” when I was 13 that I began to research it and learn more.
I was horrified by what I learned. It kept me up at night and sometimes made it hard to concentrate on schoolwork, etc.
I would say that is about as young as I would expose kids to the full story of the Holocaust, or Auschwitz in particular.
