my 71/2 year still does'nt speak well

I got fed up with the speech lessons at the schoold district where we lived, so moved to a better school district that had an onsite speech teacher.  This teacher has been an educator for 30 something years, and after talking with myself and observing my son for a few days she told me it is possible he has a mild form of cerebral palsy.  She asked  me if he had jaundice as a newborn or had ever stopped breathing as a newborn, and he had both.  She also said she could tell by his gait, that is the way he walks and holds his arms and hands.  I am waiting on his medical records from when he was born.  She said she needs to see his Apgar scores, before referring him.  She is positive she can correct his speech,and he should be able to lead a normal life.  I had taken him to many doctors throughout his life for the way he walked and talked, and not one ever mentioned cerebral palsy.  She said his is a very very mild case, and that she is almost positive that this is his problem.  He should have been in early intervention long ago if anyone would have recognized it for what it is.  Has anyone on here ever had a child that presented these symptoms?  Did they correct over time?

No I don't have experience of what you are looking for.
But I have come across classes where children with cerebal palsy (and some other disorders) integrate movement with speech.  It helps to improve the overall brain communication.  In the UK the classes are called STEPS, but it might be something different where you are.  Movement is vital to certain brain development, things like swimming, crawling, trampolining, climbing.  Things like brain gym etc.  Have a look into stuff like this as it should help.
I know its very frustrating when you realise your child has missed out on therapies for years.  I had something similar with with my son who has an autistic spectrum disorder.  But try not to look back, but focus on what to do now.
I presume he is okay with social interaction skills?
There are usually progress/percentile charts that you can use for 'typical' children.  But when you have a child with any kind of special needs you cannot get an accurate prognosis because their skills may be delayed or disordered and lower skills impact on higher skills etc.  But I think it is likely that he will improve in all areas, but you won't know to what extent.  Just do what you can and try to use any interests he has as a motivator to practice and reinforce skills.
