YouTube star and children’s educator Rachel Accurso, whose “Songs for Littles” have been viewed billions of times, meets and sings one of her trademark songs with Rahaf, a 3-year-old double amputee from Gaza evacuated by Palestine Children's Relief Fund. Accurso, who has millions of followers across social media, has been outspoken about her views that the children in Gaza face a humanitarian crisis, and says she has received both support and bullying for her posts.
