The useful verdict

Why Hippos Go Berserk! works

Hippos arrive one at a time up to nine and then leave again in the same order, so the counting runs forwards and backwards inside one story. A toddler counts hippos on the page months before they can count anything in the room.

Before you buy it

It ends on one hippo alone in the house, and a few children take that as sad rather than funny.

Themes: counting, parties, hippos, first numbers.

Straight answers

Questions parents ask about Hippos Go Berserk!

How long does it take to read Hippos Go Berserk! aloud?
About 1 minute at an unhurried pace, from a word count of 130. Reading it fast shaves perhaps a third off; stopping for questions on every page can double it.
What age is Hippos Go Berserk! actually for?
Ages 0-3 in our testing, which is narrower than the publisher's range. With 2 sentences a page and vocabulary at 2 out of 5, it asks for that much attention span and no more.
Does Hippos Go Berserk! survive being read on repeat?
Yes. It survives a fortnight of nightly repeats, which is the real test.
Is Hippos Go Berserk! 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, and it asks the child questions to answer out loud. Those three features are what keep a wriggling toddler listening, far more than the subject matter does.
Will my child memorise Hippos Go Berserk!?
Probably, and fast. The book leans on a repeated refrain, and at 4 out of 5 for re-read tolerance it survives the nightly repeats that get a book memorised. Expect your child to chant the pattern back before they can actually read.
Can a beginning reader read Hippos Go Berserk! on their own?
It is closer than most picture books. With 2 sentences a page and plain vocabulary (2 out of 5), a confident early reader can attempt it, though it is written to be read aloud first.
What themes does Hippos Go Berserk! cover?
We tag it with counting, parties, hippos and first numbers. Those are the threads that actually run through the book, not just the ones on the cover, which is how it earns its place on our themed lists rather than a keyword match.
