[Content Introduction]
◆ Bring out your baby's "round smile"! A first book that parents and children can relax with together
This book is designed for playing with your baby through skinship, accompanied by "Rilakkuma" and his friends, characters loved by both small children and adults.
Speaking of "Rilakkuma", he is always relaxed and goes at his own pace... We created this book hoping that because it's Rilakkuma, it will not only be a fun picture book time for the baby but also a relaxing moment for parents amidst their dizzying childcare routines.
Please enjoy the picture book relaxingly together with your baby.
◆ Supervised by Dr. Hajime Yamaguchi, a pioneer in "Touch Science". Scientifically supports growth
This book is supervised by Dr. Hajime Yamaguchi (Professor at J. F. Oberlin University), a leading expert in "touch science" who studies touch from both scientific and psychological perspectives. We aimed to create a book that scientifically promotes development and attachment formation through skinship.
"Touch" is the first of the five senses to develop. That stimulation is the key not only to nurturing the baby's brain and heart but also to scientifically deepening the parent-child bond.
◆ Why is "Skinship" important now?
The "happy hormone" oxytocin, which is secreted through physical contact, has many benefits for babies.
◎ Promotion of attachment formation
⇒ A stable relationship of trust (attachment) is formed through skinship.
◎ Supports brain development
⇒ Stimulation to the skin reaches the brain directly and is drawing attention in intellectual education, such as improving memory.
◎ A stress-resilient heart
⇒ Children with a stable secretion of oxytocin are said to easily acquire the ability to overcome difficulties.
Furthermore, not only for the baby, but oxytocin secretion can also be expected for the caregiver engaging in physical contact, which is said to have stress-relieving and refreshing effects.
