In today’s latest episode, I answer a listener question that will resonate with most parents of T1D kids: the emotional and practical considerations of testing siblings for diabetes markers. The decision to test siblings for diabetes markers is one that many families, including my own, approach with trepidation. The anxiety surrounding this decision is understandable. No parent wants to even begin to imagine another child facing the same challenges as their type 1. And so the question becomes: to test or not to test?  Do I want to know?  Should I want to know? Does knowing help? Or will I just feel more overwhelmed? The discussion strikes a balance between the idea that knowing if a diagnosis is coming can be powerful — we can plan, and prepare, and possibly even help delay onset with new drugs like tZield. But we also need to be gentle with ourselves, choosing testing only when we feel ready to tolerate what the testing uncovers. I also tackle how we might have to protect our children from the enormity of that information, holding it lightly for their sakes, even as we prepare for the worst.  Of course, this decision remains a deeply personal one for each family. In this episode, I provide information, empathy, and understanding to help parents make the best choice for their children and their family’s overall well-being. Hopefully, listening will offer some perspective that will help ease the your burden of deciding.
