This is Indiana, my two-year-old daughter, singing along with a Leapfrog Microphone. This toy has been around through three children now, and it still works perfectly. It's a big red plastic microphone that lets you (if you're in single-digit age) sing along with a woman with perfect pitch to four different songs, or make up your own song. If you're old enough to hold the blue button down while you sing, you can record your voice and play it back (the microphone applauds you when the recording's finished). If you're only two, your mommy holds an iRiver up to you while you sing, and captures your performance for posterity.
The last thing Indiana says is, "I did it, Mommy!"
