When I read this to my son/daughter, I like to make the sounds of the different animals. I also point out where the little owl is hidden on every page. S/he is still in utero, but I nevertheless feel like this is a worthwhile activity.


The art is simultaneously classic and modern and I'm pretty sure no child will appreciate it on as many levels as I do.

This is a stunning book, one that appeals to my artistic side (the side that loves art, even if I'm hopeless at it myself). Il Sung Na is an illustrator like no other, and the story is very sweet too. The kids really like this one, with all the different animals, and as they get older there are finer details to notice.

The text is very simple but the illustrations are deceptively simple and utterly gorgeous - I would love to get them as posters.

They speak for themselves, I think. :)
The illustrations in this book really captivated me--they are so unusual and beautiful! The story itself is a very simple one about all the different ways animals sleep--and how the owl finally falls asleep while everyone else wakes up ;-) Still, it's so beautifully told through the illustrations and a few well-chosen words that this is a true gem of a bedtime and animal story.

Owl doesn't get to sleep like the other animals do when night falls. Instead he zooms around and checks on everyone's odd sleeping habits. Finally when everyone else is waking up lonely owl is going to sleep.

Oh my gosh this book! I picked it up because of the cover art and I've read some other Asian author picture books and they were excellent so I HAD to check this one out too...

The art from cover to cover is unusual and absolutely stunning. Interestingly, much of it was done with the help of digital computer technology; and I will search out more books by this talented picture book artist. This is a gorgeous book.

The story is a perfect and reassuring bedtime story for very young children, as it goes from animal to animal talking about the ways they sleep, and then talking about them all waking up "when the sky turns blue and the sun glows bright” – except for the owl,

3.5 stars

This book follows and owl (happily you can look for it on nearly every page!) who stays up at night, and travels by various other animals who sleep at night.

I'm sure children who are curious about animals, and children who might be afraid to sleep (or of the dark) will enjoy this simple and sweet tale.

The illustrations are interesting and unique and overall I did like this a lot!

Wow. I would like to commission Il Sung Na to design my wallpaper. The illustrations in this book are exquisitely rendered and the story is short and sweet--perfect for bedtime.

Reading this every night at bedtime, I still find it sweet, and it's short enough to not get boring.

A fine book to teach how different animals sleep differently, like some keep both their eyes shut, while some only has one eye closed & oneopened.. And there are those as well which have both their eyes open. They don't even blink. They don't have eyelids at all.

This is the book just begs for you to cuddle up with your child and whisper the story quietly while looking at all of the sleeping animals and trying and find the Owl in every illustration. I've added this and a few other Il Sung Na books to my son's book wish list for the grandparents. This is a lovely book and one you definitely need to try out, I give it 5 stars.

A simple story about a owl keeping watch under a moon and how other animals sleep. A mother grabbed it right after storytime to check out. 12/16/11

This was quite popular at story time and grabbed a lot of children that were hanging around from Lap Time.

Now this book was great. My four year old niece and I loved the illustrations. She could identify every animal. And wanted to know why the owl slept at night and the rest did not. Kept entertained and seeking knowledge. Win, win, win!!

One of the things I like most about children's book is the wide range in illustrating styles. And I like the style of this book. Also, it's about animals and that is nice, most of the time. Plus, it covers one of my favorite things... sleeping. That makes it an all round winner for me, but my little girl never picks it when choosing a book for the night. We only read it when I want something different.

A fun little story about an owl who stays up and all the other creatures that go to sleep at night.

**Talking points - just because you are different from everyone else around you does that mean that you are wrong? Perhaps God just made you wonderfully different for a reason. What things are different about you and how can they help you in your mission here on earth?

A short, lightly amusing bedtime read about animals that sleep in many different ways in many different places. It's simple, but it works. Well done. The illustrations are unusual, but appealing. Nicely done.

I read Na’s A Book of Sleep to the children after showing them a few related signs (day, night, moon, stars). WE then briefly discussed the elements of the illustrations-dark sky, moon, stars, animals sleeping, etc.) I then explained that we would be doing a “magic” nighttime painting by first drawing on a sheet of heavy paper with white or very light crayons and then we would be painting over the drawings with water

Recommends it for: Parents wanting a good bedtime book
“Book of Sleep” by Il Sung Na is a picture book intended for children ages 1-5 years (N). The book tells the story of how different animals sleep as compared to the owl. I gave this book a 4 star rating. I chose 4 stars only because of the illustrations. The book itself I would give 3 stars to but the illustrations are amazing. They are imaginative and unique, the pages could easily be ripped out and framed. “Book of Sleep” does its job effectively in conveying to the reader how the owl sleeps b ...more

Owl is awake as the rest of the animal kingdom falls asleep. Owl flies overhead and watches each animal. We are given a description of how each animal sleeps: Some sleep standing up, some sleep with one eye open and others huddle close together. But when the sun comes up, it is time for owl to finally close his eyes and go to sleep.

The illustrations are made with painted textures and digital work. They are beautiful, soft, textured for interest, and fun to look at.

This is a very soothing story f

When nighttime descends, all the animals go to sleep, except for the watchful owl. So begins this bedtime book which will be loved by the young and old alike! Charming illustrations in muted tones coupled with the brief text set the perfect mood for napping.

I cannot find the words to adequately express just how much I love this sleepy time book! The illustrations by Il Sung Na are so completely amazingly lovely, that I can only describe them as eye-candy. The horse tushes and 'one eye open' bird

Every inch of every page is illustrated in this visual treat! Young readers follow watchful owl in the dark on an imaginative discovery of animal behavior. The layering and detail in Na’s mixed media spreads create a depth you feel you could fly through. The text, sweet and succinct, guides you rhythmically along, while rich yet quiet hues depict how the look of night varies in the different places the animals rest. This is a book to pore over and over. With each read, you may find a new star to ...more

Suka banget sama ilustrasi di bukunya. Seruuu ikut nemenin burung hantu mengamati hewan-hewan yang sedang tertidur dengan beragam gaya :)
paling suka ilustrasi gajah dan paus yang lagi tidur :)

Penjelasan di buku ini juga sederhana, mudah dimengerti sama anak-anak :D

Tapi, kalau buat anak-anak yang sudah bisa bertanya, harus mengantisipasi banyak kemungkinan pertanyaan dari buku ini, misalnya suara gajah waktu tidur itu berisiknya seperti apa? Burung apa aja yang tidur dengan sebelah mata terbuka d

Simple text describes many animals who are sleeping after dark while the owl watches--quiet sleepers, noisy ones, ones who sleep standing up, with one or both eyes open, etc. The stylized, illustrations ("created by combining handmade painterly textures with digitally generated layers, which were then compiled in Adobe Photoshop," according to the verso at the end of the book, which I take to mean the author used both original and computer generated drawings ) are airy, humorous (but not cartoon ...more
