Screenwise Verdict
This is a solid, functional picture book that does exactly what it sets out to do: help young kids process the arrival of a new sibling. Lucy Cousins' cheerful art and straightforward storytelling make it accessible for the youngest readers, and the emotional arc—jealousy to acceptance—is handled with warmth and honesty.
It's not revolutionary, and it won't blow anyone's mind, but that's not the point. This is the book you pull out when your 3-year-old is acting out because the baby is getting all the attention. It's a tool, and a good one. The 4.4 Amazon rating suggests parents find it helpful, and the short length means you can read it multiple times without losing your mind.
If your family is in the thick of new-sibling adjustment, this is worth having on the shelf. If not, there are more imaginative picture books out there—but for its specific purpose, Za-Za delivers.
Age Fit
Best for ages 2-5, especially kids who are about to become or recently became big siblings. The simple text and bold illustrations work well for toddlers, while the emotional content resonates most with preschoolers navigating sibling dynamics. Older kids will likely find it too young unless they're reading it to a younger sibling.
WISE Breakdown
Wholesome
88
Lucy Cousins delivers a gentle, emotionally honest story about sibling jealousy and adjustment. Za-Za's feelings of being displaced are validated, not dismissed, and the resolution comes naturally through his own discovery rather than forced moralizing. The tone is warm, age-appropriate, and models a healthy path through a common family transition.
Imaginative
72
Cousins' signature bold, colorful illustration style (familiar from Maisy) brings visual energy to a straightforward narrative. The story itself is fairly linear and realistic rather than fantastical, but the expressive artwork and relatable emotional journey invite young readers to connect their own experiences. Not groundbreaking in concept, but executed with charm.
Safe
98
Completely safe for the target age group. No concerning content whatsoever—just a zebra learning to love his baby brother. The emotional conflict (jealousy, feeling left out) is age-appropriate and resolved positively. This is as safe as picture books get.
Enriching
80
Directly addresses one of the most significant emotional challenges young children face: welcoming a new sibling. Helps kids name and process feelings of jealousy, provides a model for empathy and adjustment, and reassures them that these feelings are normal. The book serves a clear developmental purpose during a potentially stressful family transition. Not intellectually complex, but emotionally valuable.

Lucy Cousins' bold, colorful art style (think Maisy) is visually engaging for toddlers and preschoolers

⚠
What to Watch For
Very simple storyline—older preschoolers (4-5) might find it too babyish unless they're actively dealing with a new sibling
The book normalizes initial negative feelings about a new baby, which is healthy, but some kids might need reassurance that Za-Za's jealousy is temporary
