I, who do not like discs mélant natural sounds (waves, rain, seagulls ...) and soft music, I bought this CD by following the other reviews on amazon. My baby 1 month is conquered! It's great when you're stuck on the device for 1 hour and it's time for breastfeeding! Appeasement is immediate, my baby falls asleep or listening to these sweet melodies wisely. To be close to you when we have a baby!
