My two daughters are real fans of their P'tites Zazines! They love Sanshiro's children songs and we have recorded their preferred ones on their MP3 teddy bears. At night, they get to sleep while listening to their preferred music, it's great: they look at the blinking lights and we have limited the sound level so that music is not too loud!
Moreover, my elder daughter has sung with other children of her class, and we could put MP3 of her songs in her Zazine: she very often listen to them.
