The songbook is just fine. My daughter (13 months) does not like to be alone, you leave a room only and there is a huge theater. Thanks to the songbook is now a little more relaxed, it has now in which they first again handled a few minutes of concentration with the songbook. If it has then once found her favorite song, one must already so listen it 6-8 times in a row ... How long does the book, I do not know, but it makes me a pretty robust. I would recommend it to others.
