This is an old book that has aged over the years. It would be quite expensive if purchased at the original price. Although it's an old book, it still contains useful information that is relevant even now, so I'm offering it for sale. This is a set of four books covering practical knowledge about childcare and nutrition. It's perfect for those aiming to be nursery teachers or midwives. Since these are aged items, I'm selling them at a lower price than the original retail price. I haven't read them much, but they are old books and have been stored at home for a long time. Some books may have scratches or stains. I can check them if you leave a comment. I'm selling them as a set. - Book Title: Childcare & Lifestyle Encyclopedia 2001, Tamahiyo Encyclopedia Series, 1300 yen (excluding tax) - Book Title: Childcare Ideas, Tamahiyo, 1998, 760 yen (excluding tax) - Book Title: Breastfeeding Q&A, Japan Breastfeeding Association, 1300 yen (excluding tax) - Book Title: Baby Food Cooking Encyclopedia, Hiyoko Club Supplement, 2002 Thank you for looking.
