This is an amazing book to share the importance of sleeping and the benefits it has on the brain. As we move into a more and more digital world, getting enough sleep has become harder for a lot of children and teens, and sometimes it's hard to understand why it's so important. This book does just that. In a series of illustrations and pages that go in detail, the books tells us all the amazing things that happen while you sleep. Highly recommend!

What happens while you sleep is a good book to teach children about the importance of sleep. In this book, a kid has an eventful day. He goes to the zoo and he learns to write his name right. He forgets where he kept his teddy before he goes to sleep. When he sleeps, two messengers, hippo and campus sort out the memories, decide which ones to keep and which ones to throw away, and also tell the location of the teddy bear. The book is great concept-wise but it felt a bit lengthy. The illustrations are also unique for a picture book.

Despite the cute character names referencing the hippocampus and the conscious mind, there was not a detailed explanation of what really happens when you sleep, which I think was a missed opportunity. This would be good to use as a read aloud to preface a science unit but might be a bit young for a child learning about the hippocampus. In order to understand and appreciate the wordplay of the names Hippo, Campus, and Conshus, the adult reading the story would need to be prepared to give an explanation. The story itself was pretty cute though.

Beautiful pictures with lots of detail. An excellent resource for a child to have as a learning tool about the brain. I was very impressed with the book. It did not interest my 5 year old but what a great book this would be for an older child who may already be, or is about to learn, about the brain. This book was provided by Net Galley in exchange for an honest review.

Interesting book about our brain and what happens to/in it while we sleep. The book shows the brain as a tree with many branches, that keep growing to make room for newly gained knowledge and experiences. It also explains how individual memories are processed and stored differently in an easy to understand way. Not just a book for kids but for parents too, because they might just learn something as well. I certainly did. 5 Stars

As I first started to read this to my 4 year old son I wasn't sure what I was going to think of it but I was very pleasantly surprised. It is a simple story explaining what happens when we sleep and how memories are stored and why it is important that we get enough sleep.
I thought calling two of the characters Hippo and Campus was a fantastic idea.

Thank you to NetGalley and the publisher for my ARC.

Sleep is especially important for children. When they sleep, they do not simply lie in bed, but help their body grow and rest to function better.
Children have a very active life. They go to school, take care of pets, go to the park with their parents or grandparents, run with friends, play football, basketball, or volleyball, do their homework, play in front of the house or the block, etc. And they do that every day. Obviously, in the evening, their body needs rest. And sleep helps them rest and prepare for the next day's activities.
Hippo and Campus are the friends of the little Malu when she goes to sleep, and they try to sort out among the impressions and feelings she collected during the entire day.
The part of the brain that deals with regulating stress responses - it's called the hippocampus and is somewhere at the base and depth of the brain. A kind of core if you will. The hippocampus is an area of the brain responsible for long-term memory and memory formation. The researchers' results showed that lack of sleep affects the way neurons around the hippocampus "light up". This is one of the cores of our cerebral hemispheres and the author transformed it in the story as the name of 2 different characters: Hippo and Campus.

Loved it!
The illustrations were different than what I have experienced when reading children s books and so I looked up the author-illustrator's bio to see why. She is of German descent which might explain the different drawing style in this kind of books. I was amazed by it!
Also, loved the premise of explaining what happens in our brains while we sleep, a refreshing take on what dreams are like and where do they come from and how they are formed.
Clever use of the hippocampus for the names of the characters in the book Hippo and Campus. loved it overall!

Thank you for the opportunity to review this book, What Happens While You Sleep by Anna Russelmann.

Essentially, this book is about teaching the importance of sleep. It follows the story of Malu and Conshus, as well as Hippo and Campus.... get it? I like the inclusion of the wordplay in the characters' names, which reflect parts of the brain and its related processes. I think the illustrations are pretty cool, it reminds me of old classic fairy tale stories. I think that this would be a good book for reading with an adult or in a science lesson, as the connections that can be made from the plot/character responsibilities or names may be obvious to some and others may find the extra guidance in this area to be educational. Overall, I think it's a pretty cool book. I learned some stuff too!

Such a cute storyline! I really enjoyed this book. The story follows what happens in little Malu's brain when she falls asleep. Everything from the day is being processed and recorded. I definitely recommend this book to kids of all ages. A really fun read for kids! Thanks #netgalley for the early review copy.

What Happens When You Sleep is a cute story with beautiful pictures that teaches children what happens inside their brain while they sleep. Children will learn what their brain does and how their brain processes things while they are sleeping. It is written in an easy-to-understand way for kids. This would be a neat book to read to class while they are learning about science or health. Thank you to NetGalley and the Publisher for the opportunity to read this book. (This review is also GoodReads.)

What Happens While You Sleep is an ingenious way to explain to kids why it is so important to get enough sleep. While Malu is awake, Conshus watches from her watchtower and records everything that Malu sees, says, and does. Once Malu goes to sleep, everything that happens is sent to the mailroom, where Hippo and Campus work tirelessly to sort every experience into what needs to be save and what can be discarded. They must work quickly though because once Malu wakes up their job is done for the day. I love the story! I think it's a great way to demontrate to children why it's important to get enough sleep, but doing it in a way that is fun and easy for them to understand. The illustrations and the authors writing style remind me of fairytales. It was beautifully put together and I would definitely recommend this book to others.

First, let me say how much I absolutely LOVE this cover! It is amazing! This is a cute story. It does not get into deep science explanations of what happens to your brain whilst you sleep, but it gives a simple and fun peek into a little of what is going on. I have to say that if I had read this to my kids when they were little, they would probably start worrying that their brain would accidentally throw out something that was important which would lead to further reader has and conversations.
The artwork is lovely. There was a lot going on in the pictures, which I thought were a good thing. They were fun to look at.

This is a well done and creative story that I do believe children will love. Also the illustrations are beautiful.

Thank you to Netgalley and the publisher for letting me read this book in exchange for an honest review.

Beautiful illustrations and a creative story. This is a different type of book but kids will enjoy it. This will be a great book for inquisitive children and those who enjoy a nice story.

This book has a cute concept which, in my opinion, doesn't do enough to setup or explain what's going on for it to fully land. Young girl Malu goes to sleep wondering where her Teddy Bear is - once she drifts off we're introduced to the characters and setting of her mind and what goes on inside of it while she sleeps. Readers are not introduced to these concepts, rather, they just happen. A lot is understand via context and throughout the plot of the book, but I found myself confused at the beginning. Am I supposed to know who these characters are and what they're doing? It's a cute concept but I feel like the book can do a better job of letting the reader know what's going on, especially if young children are the target audience. The illustrations are beautiful and the story ultimately ends on a positive note.

An intriguing book that I think deserves to do well. I thought we would get some of the science of dreaming in this look at what happens in our minds while we're in the Land of Nod, but no. Instead, Conshuss closes up her watchtower and packs up, packing up most of our usual functions at the same time, leaving Hippo and Campus the night shift, of sorting through our memories, keeping the good ones to treasure and getting rid of the dross. But surely they can't do all that AND solve the problem their host child has regarding a missing teddy bear?! A visual style that would make this creator high on the list of anyone wishing to get a fairy land of wonder illustrated, this has a quite surprisingly high level of drama in amongst the science. Not everyone will love it, but there is a welcome chance that twenty years from now a newly-graduated psychologist finds this and remembers how it was this that started all her career off.

It's a cute story with lovely illustrations. I'm not too sure that, while reading it, children will be able to understand what happens. Perhaps their parents could explain it to them a little if they read the book with their children. But the premise is really good, and can really give children basic insight to what goes on while they sleep. And once again, the illustrations were beautiful!

This book has a lot of information and is cute with the character names Hippo and Campus. I think readers would need a background understanding of the brain to truly understand this book. While the story and premise are cute, just as a story I don’t know that kids would get it.
