The five words every mom needs to know:

"I'm hungry!"
The word: Neh
Where it comes from: The noise made when a baby pushes his tongue to the roof of his mouth because he wants to eat, "neh," is an infant's sucking reflex with sound added to it.

"I need to burp!"
The word: Eh
Where it comes from: When a big bubble of air is欧 caught in your baby's chest, the sound you hear is "eh," as your baby tries to get the burp out.

"I'm tired!"
The word: Owh
Where it comes from: An audible yawn, you can spot the word because your baby's mouth forms an oval shape as he says it.

"I'm uncomfortable!"
The word: Heh
Where it comes from: Your baby's response to a skin reflex (the same one that governs sweating) signals irritation -- a wet diaper or an itchy bodysuit.

"I have gas!"
The word: Eaire
Where it comes from: If a burp doesn't make it out, it moves through your baby's digestive system -- "eaire" is the sound you get as the muscles of the intestine and stomach tighten to force the air bubble out.
