Actually we wanted as long as possible leave these 'Dudelspielsachen' out of the toy inventory for our child. How so, you get those things then just given ... The first reaction on our part was therefore more subdued. But our kid loves this book dearly and we find it now even good! The caterpillar learns the kids (and parents) common children's songs, backed by colorful pictures. The caterpillar is in spite of all parents with children: two volume options offer the children's and parents' ears choosing where even the little Louder is well tolerable. As long as the children are young, they do not even do it, the knob to adjust arbitrarily. 6 different songs sound either by itself as soon as the pages are turned (2 songs per double page) or when pressure on the nose of the stick that lights the way great red when a song is heard. Also on the inner sides are 2 small green light, that light up when the song of each page will be played. The crawler body has 3 colorful buttons that are easy to press and have 2 functions and some play of the images of the insides, when the pages are opened ('orange cat' or '3 cakes' or similar), or the songs Play in flip closed. The bead is made of sturdy plastic, coated the insides with saliva-resistant foil and so the caterpillar holds something rabiaterem or wetter [; 0)] was dealing with the kids. Since our little scary like rumdrückt of buttons, he finds the caterpillar great, so great that you just have to temporarily withdraw from the market in order not to lose their nerve. I'm not an educator, but from about 7/8 months, the caterpillar is quite recommendable. However, it must be remembered that older children can repurpose the caterpillar to Nervtöter: The child of acquaintances is 2 1/2, he found it just fine, over and over again to press the caterpillars nose, then of course a very short time from song 1 Song 2 and again returns. This went on all of us within a short time to the threshold of pain, as great as it may be for the kids, but since then heard of fun on. At least for the parents! Pity is that the songs stop in the middle when you turns the pages, what our child and really love makes the songs so not full of 'kennen- / learning' are. Therefore, a star deduction for an otherwise very entertaining toy for your child!
