Goodnight, Leena…. Sleep Tight
A Doorway to Dialogue on Sleep

Can’t get your kids to sleep on time? Students falling asleep in class? This is a remarkable story to help parents ingrain healthy sleep habits in their children. It is an entertaining and informative story that incorporates science to teach children why sleep is so vital for their physical and mental health.

Leena never goes to sleep on time, so she never gets enough sleep. Why sleep when she could play her cool new video game instead? Interestingly enough, the main topic for this week in her class is on the science of sleep.

Leena learns about the scientific knowledge related to sleep, yet she continues to play her video games and talk on the phone late into the night. She never feels rested and excited to start her day.

As she goes through her days feeling crabby and tired, will Leena finally uncover the secret of a good night’s sleep?

“What an insightful evidence-based illustration of a prevalent problem every household faces today, especially in our zoom-filled pandemic world. Not only is it based on current research for sleep benefits and underlying mechanisms, it also documents a journey for children to identify with.  My daughter and I both loved reading it and highly recommend it. Congrats to the Grewal mother- daughter team for bringing such an important issue to light.”

“As an educator with 30 years of experience teaching children of all ages and abilities, it is great to see a book about sleep included in a Be Well children’s book series. “Goodnight Leena, Sleep Tight” is a well-written, beautifully illustrated book that helps parents teach their children the importance of sleep. I know from personal experience a well-rested student is generally more successful at learning and getting along with others both in and out of the classroom. Baldev and Harlene Grewal’s enjoyable and informative book about sleep would make a great bedtime story. It could ultimately help bedtime routine go a little smoother for both parents and children.”
