It offers a relatable look at how plans can go awry without vilifying the younger sibling, making it a comforting read for children aged 3 to 7.
None. The book is entirely secular and grounded in the everyday realities of domestic sibling life. The resolution is realistic: Max's antics might change the plan, but the bond remains intact.

Sign in to write a reviewAn older sibling (5 to 7 years old) who takes their projects very seriously and often feels that a younger toddler sibling is a 'wrecking ball' to their plans.
No previewing is necessary. This is a very safe, 'read cold' book that relies on the visual humor of Max's facial expressions and his unexpected contributions to the lemonade stand. A parent might reach for this after hearing 'Max is ruining everything!' or seeing a carefully constructed fort or game dismantled by a younger child's curiosity.
A 3-year-old will likely identify with Max, finding his interruptions funny and his desire to join in relatable. A 6-year-old will deeply empathize with Ruby's frustration and the struggle to stay on task when a younger sibling is present.
Unlike many sibling books that focus on jealousy or anger, Wells captures the specific 'business' of play. It highlights the clash between a child's growing desire for logic and a younger child's pure imagination.
Ruby and her best friend Louise are determined to earn money by selling lemonade. Their goal is specific: they want to buy matching rings. However, Max, Ruby's younger brother, is constant interference. He wants to sell his own items and play his own games, which don't exactly fit the professional image Ruby is trying to project. The story follows the friction between Ruby's organized ambition and Max's impulsive play.
