Sleepovers, grandparents, and separation anxiety.


It's time for Sleepy Sheepy's very first sheepover! But when it's time for bed, Sleepy Sheepy CANNOT SLEEPY! You see, his blankets scratch, and his pj's don't match! Sleepy Sheepy...misses his home! Will Grammy and Grampy ever get their favorite little sheep to sleep?

Opening Lines:

It was finally THE BIG DAY.

Or rather - THE BIG NIGHT?

It was time....

for Sleepy Sheepy's...

very first...


What I LOVED about this book:

From a great spread of bouncing on the bed to a double spread closeup of Sleepy Sheepy's face and exclamation of "SHEEP-OVER!" the little lamb's excitement for a first ever sleepover is palpable. I love Sleepy Sheepy's packing of necessities for one night. It's such a great image, no wonder it ended up as the cover.

Sleep Sheepy's initial excitement to have "his two favorite folks, all to himself!" is quickly squashed when Ma and Pa say goodnight and drive away. Leaving Sleepy Sheepy feeling ...

But he couldn't explain why. Except that everything is wrong. His blankets scratch, his PJs don’t match and "his tummy got twisty, and his eyes got misty." Not only did he miss home, but he couldn't sleep! Grandparents to the rescue! Grampy makes cookies and Grammy read Goodnight Mooo'n (with a cow on the cover!)

Soon they have the perfect sheep-over party going and Sleepy Sheepy starts to relax and "before he knew it...." I love that Pete Oswald's softly colored illustrations are packed with humor, from Grampy's international tater collection to some of the items Sleepy Sheepy packs as necessities - a spatula, sports equipment, and a star. The more you look, the more fun things you find. And they combine perfectly with Lucy Ruth Cumming's sparse text, fun word play, and sprinkling of rhyme, to create a wonderful lighthearted and touching intergenerational book. Perfect for little kids embarking on their own first sleepovers and readers looking for a sweet bedtime book.

  • make your own sheep puppet or a puppet for all three characters and have your own sheep-over party.

  • what special things would you pack for a sleepover? Would it be different if you were staying at a friend's or a family member's (grandparents or cousins) house?

  • if you have stayed the night away from home, what helped you to feel more comfortable?
