During the first early intervention appointment, you will have an early intervention intake coordinator and a therapist come to your home or if your state does it in a center, then you will go to a center.
During this appointment, they will go over the milestones that your child should be reaching, the ability level that your child should have and they'll discuss what needs your child has as far as therapy. There are three specific kinds of therapy that a child usually needs taken care of in early intervention. The first is physical therapy which is large muscle groups; arms, legs, trunk control.
Second is occupational therapy which are small muscle groups, such as, the muscles of the mouth, your tongue, your fingers and your toes. Third is speech and language pathology. Obviously, speech therapy is for speech, but it also helps with oral control and feeding. At that first intake appointment, they will determine how often you need to have therapy and what length that therapy should be. For example, they may determine that your child needs physical therapy three times a week, for thirty minutes.
Following that, the therapist will either come in your home or you will take your child to a center to have that done.
