I'm no longer reading these, so I'm selling them all to declutter. This book delves deeply into parental habits that affect children's grades and development. It contains a wealth of important knowledge and practical advice on childcare, helping parents understand their role. Individual books are 550 yen each. I will create a dedicated listing, so please let me know if you're interested. Please be aware that there may be some folds or stains from storage and use.
