Had given the tip Toi 5th birthday to my son. He was skeptical at first, it has then tried fairly quickly and was then "finished". Did then hingestzt me with him and looked at him again with the pages. Here us is only noticed what everything sounds makes (itself the cuckoo in the tree). Meanwhile, he loves this book, and even the 2 year old sister is totally excited (especially on the songs, both by heart and can sing diligently). It is a pity that the sides relatively quickly "scratch" when you firmly on the side pushes the pin (which happens in any case!)
But on the whole, I can only recommend the tip Toi and going to Christmas also give more things about it!
