What is a wombtwin survivor?

A wombtwin survivor is someone who lost a twin before or around birth. This loss includes neonatal death, stillbirth, miscarriage, abortion and a "vanishing twin" pregnancy.

My research and support work extends to the parents of the survivor and also to their siblings.

This loss also includes a multiple pregnancy which resulted in the birth of twins or more, but during which one or more of the babies died before or around birth.
