"First-Time Mom & Dad's Discipline and Brain Development: You'll understand the essential "brain-boosting" tips to do before your child is 0-3 years old!" Naoko Narita Price: ¥1300 I bought it, but I haven't read most of it. There are a few scratches on the cover and spine. If you don't mind, please consider it. I hope it will be a helpful hint for childcare (^^) #NaokoNarita #Naoko_Narita #Book #Lifestyle/Household"
