Hours. Six month review period is typical. Talk to your service coordinator to find out whether they can review the service earlier if there is no improvement after three or four month the treatment starts.

If you want to get the best treatments that you think it is right for your son, you probably will need to pay for it. The state program only provides typical service, meaning average.

I paid for a second diagnosis and am paying for two private speech therapies. I was in waiting list for more than four months for both therapists. So it also take a long to setup the private therapies since they usually are fully book even you are willing to pay yourself.
