We have already bought the game clock in pregnancy and placed on the abdomen. Since it is relatively loud our baby could hear the melody well. Even after birth, the little joy at the music box. Every time he hears the melody, he is all smiles. The music box has beautiful colors and not too many details. The melody has a really good and clear sound quality in our music box. If it were up to our son, the playing time of the song could certainly be longer, but it satisfies us ;-) As they do not use to fall asleep, but in between.
