The target audience for the DVD Kodomo Challenge Baby is mainly children aged 0 to 1 year old. There are some stains, but it is viewable. Another CD was also listenable. I'm also including two CDs that were often listened to around that time. I used to play them in the car when I was pregnant. The sounds of Disney and children's songs were pleasant, and after the baby was born, I would play them during nap times. Questions are welcome in the comments. The sound has been confirmed, but I haven't listened to everything, and these have been stored at home for a long time. Thank you for your understanding.
