Anna and her partner were thrilled with the news that they would be expecting not one, but two identical twin girls. Anna was carrying monochorionic or MCDA twins, meaning her two girls were sharing one placenta. When the doctor explained the plan for her pregnancy, a long list of potential complications were briefly mentioned. But everything looked like it was progressing beautifully, and Anna allowed herself to imagine her life as a mum of two. But at 19 weeks, everything suddenly changed. Diagnosed with Stage 3 Twin-to-Twin Syndrome, Anna was rushed for surgery on the placenta of her unborn babies. The next day came the devastating news that one of her daughters had not survived the night. What followed was a tumultuous rollercoaster of grief, loss and a tiny sliver of hope. After her waters broke at only 21 weeks, Anna describes the way her ‘little one’ held space for her big sister in the womb as she held on, against all odds, to survive.
