My daughter started playing there at about 6 months and then quickly realized she was hearing his voice into the microphone. I sing with it in the microwave which earned us crazy laughter and good times complicity :) She loves to turn the pages, make tamtam and dog. I confirm that the micro wire is too short, the micro sensor does not always work very well and the batteries wear out quickly. However my daughter mistreats his toy, pulled the microphone, crawling over and plays very often! I find it very solid! 2 volumes of sound. Two game modes. Sounds nice. Full of light and color that baby loves. He moved quickly in standby if the child no longer plays, which is appreciable for the ears! All children who come to us adore. I recommend it!
