A friend of mine just forwarded this link of an old Oprah episode where they explain the language of babies aged 0-3months. Here are the five biggest words used by babies trying to talk to their mommies
"NEH" - I'm Hungry
"OWH"-I'm Sleepy
"HEH"-Discomfort (dirty nappy,feeling too warm/cold)
"EAIR"-Lower Gas
"HEH"-Wants to Burp
Here's the video that has examples in it too. Fascinating stuff!
