Millions of Americans speak a language other than English at home, and many of them are young children. Picture books are starting to reflect this diversity. Monica Brown has written more than a dozen children's picture books with text in both English and Spanish. Raised bilingually by a South American mother and North American father, she says her inspiration comes from her own upbringing. "It wasn't until I had children ... that I decided to write for children," Brown tells NPR's Arun Rath. "I knew I wanted to write stories that reflected the multi-ethnic, bilingual nature of my own family."
