I have been where you are. By the way you have been miss informed on one point about ECI, they end at age 3 not begin!!! I would contact them because they have a family cost share and I fairly sure yours would be 0 dollars out of pocket. Have him evaluated for all areas and they will give you someone that will come directly to your home for usually one hour a week home visits. They also have a program to help you transition him into other services if he doesn't qualify for theirs as well as when he turns three and graduates from their programs. Hope they are helpful to you as they have been for us. Andrew particularly would be so far behind without ECI, I will be eternally grateful to them for what they have done for my babies.
What kind of speech issues is he having? I didn't notice anything when I was around him but then again both of my children have been speech delayed. Greyson seems to be thriving with no signs of low muscle tone !! Praise God! He is sitting up without support and Adam even saw him trying to get on all fours today!!!
