A parent might reach for this book when their older child is struggling to adjust to a new, noisy, and attention-stealing baby brother or sister. This story follows a young girl who is so fed up with her new baby brother that she becomes convinced he is an alien from outer space. She begins a hilarious and detailed investigation, documenting his strange habits (like drooling and babbling) as proof for her sci-fi theory. The book brilliantly validates an older sibling's feelings of jealousy and frustration through a humorous, imaginative lens, making it a perfect choice for early chapter book readers ages 7 to 9. It offers a funny and validating way to open up conversations about the challenges and eventual love that come with a new family member.
The primary theme is sibling jealousy and the feeling of being replaced, which is handled metaphorically through the alien premise. This creative framing allows the narrator's anger and frustration to be expressed in a safe, non-malicious way. The resolution is gentle and hopeful: the narrator doesn't abandon her theory overnight, but small moments of connection with her brother begin to soften her perspective, suggesting a gradual journey toward acceptance and love.

Sign in to write a reviewThis book is perfect for a 7 to 9-year-old with a dry sense of humor and a big imagination who is currently struggling with the arrival of a new sibling. They feel overlooked and irritated and will deeply relate to the narrator's dramatic complaints and her clever, imaginative coping mechanism.
No preparation is needed. The book's humor and relatable premise make it easy to dive into. It's an excellent conversation starter, so a parent should be ready to talk about the real feelings behind the funny "alien" observations after reading. A parent has heard their older child say, "You love the baby more than me!" or "The baby ruins everything." The child may seem withdrawn, resentful, or is acting out for attention since the new baby arrived.
A younger reader (age 7) will focus on the slapstick humor of the baby's actions and the fun of the narrator's secret mission. An older reader (age 9-10) will also appreciate the sarcasm, the subtext of the narrator's jealousy, and the cleverness of using the alien metaphor to process complex emotions.
Unlike many sweeter books about new siblings, this one fully embraces the older child's negative feelings with unapologetic, laugh-out-loud humor. The science fiction metaphor is a unique and brilliant device that validates frustration without shame, making the story feel more authentic and entertaining than many of its more earnest counterparts.
The narrator, an elementary school-aged girl, feels displaced and annoyed by her new baby brother, Adam. To cope, she develops a theory that he is not human but an alien from Planet Zog sent to observe Earth. She begins keeping a secret notebook to document all his bizarre, non-human behaviors: his strange language, his messy eating habits, and his ability to control adults (their parents) with his mind. The plot follows her comical "scientific" investigation as she tries to gather enough evidence to expose him, all while navigating her parents' complete obliviousness to the "alien" in their home.
