International Society for Twin Studies - ISTS

26/03/2026

When a family loses one or more babies during a multiple pregnancy, the path forward can feel overwhelming and disconnected. This session of the ICOMBO webinar series explores how healthcare providers and support organisations can work together more closely to catch families who might otherwise fall through the gaps. By blending clinical research with real-life stories, this international panel looks at how to provide the kind of care that truly understands the unique journey of multiple loss.

Hosted by Nichole Cubbage of ICOMBO and the International Vanishing Twin Syndrome Foundation, the panel features Millie Cann of Skye High Foundation, Nicholas Embleton, founder of the Butterfly Project, and Sharon Darke and Suzie Scofield, co-founders of Footprints Baby Loss.

Join the conversation on Friday 17 April 2026 at 6 to 7 PM UTC, 7 to 8 PM BST, and 2 to 3 PM ET, or on Saturday 18 April at 4 to 5 AM AEST.
