The useful verdict
Why But Not the Hippopotamus works
Every pair of animals joins in and the hippo is left out on every single spread, which a two-year-old feels long before they can name it - and then everyone stops and waits for her. The armadillo being left out at the end restarts the joke.
Before you buy it
The ending is one silent beat and adults routinely read straight past the pause the book is built around.
Themes: belonging, animals, rhyme, joining in.

Straight answers
Questions parents ask about But Not the Hippopotamus
- How long does it take to read But Not the Hippopotamus aloud?
- Under a minute at an unhurried pace, from a word count of 60. Reading it fast shaves perhaps a third off; stopping for questions on every page can double it.
- What age is But Not the Hippopotamus actually for?
- Ages 0-3 in our testing, which is narrower than the publisher's range. With 1 sentence a page and vocabulary at 2 out of 5, it asks for that much attention span and no more.
- Does But Not the Hippopotamus survive being read on repeat?
- Yes. It survives a fortnight of nightly repeats, which is the real test.
- Is But Not the Hippopotamus a good book for a child who will not sit still?
- It helps that it rhymes, and it has a refrain a child can join in with. Those three features are what keep a wriggling toddler listening, far more than the subject matter does.
