Finally, the popular "Listen Up" books are available for the very youngest. Even 1-year-olds can embark on a search for the hidden animal babies: Where has the kid goat hidden? Who is lying in the dog basket? Who is the donkey mother looking for? The answers are hidden behind five sturdy sound sliders. Just pull out the slider, and the answer appears and sounds. In familiar sound quality and, of course, beautifully illustrated. The play effect corresponds to the motor skills of toddlers, allowing them to explore their books all by themselves. An important aspect that enhances the fun of play. A sound playbook for children aged 12 months and up. Attention: In dim light, the sound effect will not be triggered—so it's best to go on a search for animals during the day!.
