O, God, another Mozart study. This one says playing Mozart to preemies for 30 minutes once a day makes them grow faster. They are also calmer and less likely to be agitated, so they are expending less energy, which may account for the weight gain.
They are going to try different types of music and survey moms to see what kind of music the kids got in utero and then play that music to other kids.
This study doesn't sound flaky to me. I hope it gets extended and replicated before parents find out about it.
