CDs are there to decorate and have no specific function, but allows the child to become familiar with the form of insertion into the same hole shape while staying basic.
The four songs are short, but very friendly and will quickly takes to hum them.
The sound system with a medium and high level adjusts the sound to his liking.
The child can retrieve CD through the front door and this one enthusiastically say the words "Open" / "Closed" every time it is opened / closed.
A great gift given the price that has pleased our son.
