We often hear stories of parents parents who rally for their children when the chips are down — the mom on a crusade to understand autism, the mom who is educating America about lead poisoning or the mom who declared war against filthy play areas. Roberto D'Angelo and Francesca Fedeli have a similar story to share of hardship and triumph. But in this candid TED talk, they also share the moments in between the tragedy and the turnaround.  

D'Angelo and Fedeli thought their baby boy Mario was healthy until at 10 days old, they discovered he'd had a perinatal stroke that left him unable to control the left side of his body. They started the nonprofit FightTheStroke.org to open up a dialogue about the devastating effects of perinatal, neonatal and pediatric strokes. But they don't talk about that organization in their TED talk. Instead, they talk about the dark times when they looked at their son and felt like failures. When they asked questions such as "Would he ever be "normal?” and "Why did this happen to us?"  

Sure, their talk is about stroke and how it affected their son, but it's also about vulnerable parents who faced their fears and have changed their lives for the little boy that they love.
