🎤 Interview: Nellemieke’s Journey with Her Daughter’s Klippel-Trenaunay Syndrome 💙

In this moving interview, Nellemieke shares her daughter’s journey with Klippel-Trenaunay syndrome, initially misdiagnosed as CMTC.

Despite these challenges, she thrives in daily activities like biking and school, though social situations can be tough due to others not taking her condition seriously. 😑

🎤 Interview: Edith Raap & Minke Verdonk on Navigating Living Loss 💙

In this heartfelt interview, developmental psychologist Edith Raap and orthopedagogue Minke Verdonk dive into "living loss," the recurring grief parents experience when raising a child with a disability like CMTC. It’s not just sadness—it’s a mix of helplessness, frustration, and even shame that can resurface unexpectedly. Yet, they emphasize that these feelings are a normal response to an abnormal situation.

Through their podcast, lectures, and research, they’re giving parents space to express this ambivalence—loving their child deeply while grappling with loss. Patient associations play a vital role in fostering connection and relief. Let’s normalize these conversations!
