"We don't address the cause, we treat the symptoms"

Probably the BIGGEST mistake in healthcare in the United States today!  In the almost 15 months Jaylyn has been on this earth, I have heard this phrase more times than I can count. I cringe. I start to believe my brothers conspiracy theories. It makes entirely too much sense to address the cause and do something about it. However,  the cause is often ignored and only the symptoms are treated. No matter what your age, stage, or diagnosis. If you've gone to the doctor for a problem, the answer is 9 times out of 10 a prescription to treat the symptoms. 
My BIGGEST problem with this?!?! Jaylyn has 2 extremely rare brain abnormalities.  Do I expect early intervention to become immediate experts?!?! No of course not! But I do expect them to understand that although "The State" says they "normally" wont provide speech therapy until after age 2, take into consideration that alone, either/or of these diagnoses affects speech. Most of these kids are non verbal. ADDRESS THE CAUSE! Why wait 2 years and allow those speech and swallow muscles to become weaker?!?!
Jaylyn will be 15 months old soon. She doesn't speak. She vocalizes some sounds. Mostly vowel sounds. But no purposeful speech. I do get excited when she makes those "ma ma ma" sounds. I am hopeful that she will be one of the lucky few that can speak. She is determined!  As am I to make sure she gets everything she needs to reach her full potential. 
But addressing only symptoms? So put her on meds to stop the constant drooling instead of addressing the fact that her facial muscles are weak on the right side? Does that make sense?!?! Only in 'Merica.
