Martha Mumford has loved children's books forever. Her mother was a librarian which gave her access to a wonderful array of books from a very early age. Hooray! It's a New Royal Baby! is her third children's picture book and she is delighted to be working with Bloomsbury. Martha loves baking, patchwork and has a mild obsession with interiors magazines (although she freely admits that the ideas she has found therein have yet to be translated to the interior of her own home!). Martha lives in Berkshire with her husband and young daughters.

Ada Grey has worked as a successful illustrator of cards, gifts and stationery for many years, and she is very excited to have developed a strong and appealing new illustration style for picture books. Shhh! Don't Wake the Royal Baby was her first picture book for Bloomsbury, and marked the beginning of a brand-new, successful series. Ada lives in Brighton with her family.
