Our now eight months old son loved the first crumb Mucke CD in its first three months of life, although not so great - probably too much for a "newbie". But since he was about 5 or 6 months old, he finds the CD increasingly great and the second crumbs Mucke CD also. He loves the crumbs Mucke to dance with us or to romp or simply to listen to something quieter pieces - especially beautiful at bedtime.
We have a few other CDs with children's music, but the CDs of Christiane Weber have been the only ones to get him during boring car trips in a balanced mood and our times bring parents a quiet drive with him.
