aaagghhhh I had to give up reading that - because i dont think any of it is conclusive evidence that it helps babies, just their opinion... sort of. lol its not really a fair scientific study either is it we all know how quickly babies change and devlop they could have got the babies before and after a development spurt and that could have caused the improvement.
blimey. Wonder if they'll invent baby brain training apps for phones or the DS or Wii now!
