Queensland twins, Harper and Cleo are as tight as they were in the womb, which was so close their umbilical cords knotted together.

Their mum, Kate Lucas, gave birth to her twin girls 8 years ago, and the birth story is nothing less than a miracle.

The twin girls were born under strange circumstances that occur in less than 1% of twin births.

They were monoamniotic monochorionic (MoMo), which means they shared one placenta and grew in the same amniotic sac, because of this, their umbilical cords knotted together which could have killed them.
