No question for my eldest son to go to bed without his "beautiful songs", as he calls them. And it lasts for 7 years! Suffice to say that this CD was really a success. And our youngest son takes the same path. This CD has been played so much, worn, taken in all our travels that I was much obliged to redeem it. Do not hesitate if your child has trouble falling asleep at night or if you yourself are stressed (e) ... A delight!
