In my search for colic remedies, I came across a video of a woman that was exceptionally good at deciphering sounds. When she had a babe herself, she discovered that the baby made 5 distinctive sounds, each associated with their own specific need. The baby, in a way, was trying to tell her what he wanted. The sounds were reflexive, and if they aren't properly responded to by the 3 month mark, the baby stops making them.
The first is the sound for hunger, a "neh" sound, made from the tongue in the roof of the mouth, much like the baby would do for sucking. Then there's the "eh sound, similar to the sound made if you try to burp. The "heh" sound is discomfort, like if they are wet. A bearing down "earie" sound is what they make when they have gas in their guts, and "owh" is made when they're sleeping, kind of like a wanna-be yawn.
I thought it was bogus, so I tested it out that day and night. I couldn't believe it was true. All of it! I was so surprised to hear my baby trying to specifically communicate her needs to me! This made my response to her a little different than the usual rundown of: check the diaper, put her on the boob, re-check the diaper, burp her...She makes a little different sound than "owh" for sleepy. Her's has more of an 'm' sound attached. But how cool?!?! With this information , in addition to the "whoosh" and swing, makes taking care of her more interesting and much less anxiety provoking.
