We have this CD / DVD given to our daughter 4 weeks prior to enrollment. Our daughter hears the CD almost every day up and down, while she has already learned in no time to pay attention to the dangers of traffic. I can not find every day on their way to school and in the afternoon in the city if they themselves transport justice behaves and commented on the behavior of all our people meet ends positively or negatively or be outraged. :-)) Also to me the texts did not miss its mark. I've always thought that I do justice traffic driving car but now I fit much better on children in traffic. The DVD also contained at the same time really funny, because it's still the original version from the 80s is (cars still without headrest = rear which I use to indicate our daughter on why the headrests are so important ...) CD and DVD are highly recommended !!
