This is a parent's guide from Kodomo Challenge (^^) (I'm selling the books for children up to one year old separately! I'll give a discount to those who want to buy them together ♡) It's in good condition because I haven't read it much ♫ It was reassuring to have this instead of searching the internet for everything! Set includes books for children aged 1 year 1 month to 1 year 10 months and an unopened English trial DVD! This is a set of picture books and guides packed with information helpful for baby's growth and childcare! It's in good condition, but please understand that there may be oversights as it's a personal inspection ^ ^
