[quote=Anonymous][quote=Anonymous]But gas doesnt JUST happen and happen for hours on end.

While not your problem they really need to do more for their baby than the pediatrician is willing to advise. Babies dont just scream for hours on end. Screaming or crying is pain.

Are bowel movements normal? Does she have any other symptoms?

Screaming is a biological response to pain. "GAS" is not a good enough explanation. Its also affecting your child as hearing another person scream goes straight to her amygdala. 
"Normally, your brain takes a sound you hear and delivers it to a section of your brain dedicated to making sense of these sounds: What is the gender of the speaker? Their age? Their tone?

Screams, however, don’t seem to follow that route. Instead, the team discovered that screams are sent from the ear to the amygdala, the brain’s fear processing warehouse, says Poeppel.

“In brain imaging parts of the experiment, screams activate the fear circuitry of the brain,” he says. “The amygdala is a nucleus in the brain especially sensitive to information about fear.” That means screams are inherently considered not just sound but a trigger for heightened awareness.

From these screams, Poeppel and his team mapped “roughness,” an acoustic description for how fast a sound changes in loudness. While normal speech modulates between 4 and 5 Hz in sound variation, screams spike between 30 and 150 Hz. The higher the sound variation, the more terrifying the scream is perceived.

Poeppel and his team had volunteers listen to different alarm sounds and found people responded to alarms with similar variations: The more the alarms varied at higher rates, the more terrifying they were judged to be.

That huge variation in scream roughness is a clue to how our brains process danger sounds, Poeppel says. Screaming serves not only to convey danger but also to induce fear in the listener and heighten awareness for both screamer and listener to respond to their environment."[/quote]
