A picture book set themed around parent-child interaction and play. 1. "Let's Play, Daddy!" Kagaku no Tomo Masterpiece Collection Written by Keiko Hamada Are you playing with your children? Jumping, climbing, hanging – parent-child play involves physical contact. Even a little rough play is okay for children. Rather, they enjoy parent-child play while happily making a fuss. We deliver a unique and fun "play encyclopedia" born from many ideas from readers. (Kagaku no Tomo No. 291) 2. "Let's Play, Mommy!" Out of print, rare! Kagaku no Tomo Masterpiece Collection Editorial Review: In these times when it's said that it's difficult to have physical contact between parents and children, are there any mothers and fathers who are wondering how to play with their children? Following "Let's Play, Daddy!", here comes the second book in Keiko Hamada's "Let's Play Series," "Let's Play, Mommy!" With Daddy, there were some exciting games, but with Mommy, there are many gentle and warm games like "apron theater" and "when the flowers bloom, the leaves shine." But even with Mommy, with "warm overcoat" and "hug machine," you can hug and lean on each other as much as you want, and that becomes a trigger for parents and children to fully exchange emotions and release from the bottom of their hearts. Oh, how fun! This book is full of parent-child play. Keiko Hamada's dynamic illustrations are also wonderful. It's a picture book that's fun to read and fun to play with. Perhaps because it's popular and rare, "Mommy" is priced from 1980 yen including shipping for used copies, and even used copies with reading wrinkles and stains are priced at 1990 yen. Good condition copies are over 3000 yen including shipping. "Daddy" is not as expensive, with copies starting from 627 yen. Perhaps because the "Mommy" book is helpful in childcare and at work? I have two sets, so I will give one set to someone who is looking for it. Both have scratches on the cover, but there are no noticeable scratches or stains inside. Not for individual sale.
