Hidden Away

You are sometimes known as Babushka or Matryoshka.
You wear a peasant dress,
Given by my Grandad,
I hold you in my hand,
Precious like a child's life,
As lucky as a four leafed clover.
You were carved with a knife,
Piece by piece I take you apart,
I break off your head,
And open your heart,
Inside you there's a doll,
And another and another,
As soon as I think you're all there,
I discover another,
My Russian Dolls.
