I wanted to share this with everyone, since it has helped me to understand my baby's needs. (I saw this on Oprah). Basically, researchers have discovered a way that babies communicate with the world. It's pretty easy to understand once you know what sounds/words mean what. Neh="I'm hungry" Owh="I'm sleepy" Heh="I'm experiencing discomfort" Eair="I have lower gas" Eh="I need to burp" Here is the link to see the video that shows actual babies making the noise. http://www2.oprah.com/tows/slide/200611/20061113/slide_20061113_350_102.jhtml It's most useful for 0-3 months age group. Supposedly, if the noise/word doesn't gain the response that the baby needs the baby will cease to use to noise/word after 3 months. I had recognized my little one saying "NEH" when she was hungry and it was surprising to then see it be a universal noise babies make.
I too saw this on Oprah, and I listened to my 3 month old make some of those sounds, which I thought was really interesting. By this time, I think I have her sounds and cries figured out, but it is still good to know.
