Through it all, Juana can always count on her family's steady and secure love to help solve even the biggest problemas. The result is a thriving, buoyant, confident young Juana who demonstrates that balancing new changes with old favorites is achievable and, indeed, can be done with humor and grace. --The Horn Book (starred review) Medina's illustrations are a wonderful addition to Juana's first-person narration, truly bringing her emotions and quirkiness to life. Spanish words are sprinkled throughout the text but are italicized so that monolingual young readers will get their meaning through context cues. Medina's charming follow-up to her Pura Belpré Award-winning Juana & Lucas (2016) doesn't disappoint.

--Booklist This gentle book brims with full-color illustrations of sturdy, big-hearted Juana and her bright, cheery world. Peppered with Spanish, it gives younger readers a window into a life both different and very like their own. --The Plain Dealer.
