Dear,
Welcome to HCM
We understand your concerns
I went through your details. Once the child's IQ score falls down below 70, it is
intellectual disability. Early identification of children with developmental delays is necessary to begin receiving early intervention services. The mainstay of treatment of MR/ID (mentally retarded / Intellectually retarded) is developing a comprehensive management plan for the condition. The complex
rehabilitation plan for the individual requires input from care providers from multiple disciplines, including special educators, language therapists, behavioral therapists, occupational therapists, and community services that provide social support and respite care for families affected by MR/ID. The procedure is tiresome and the best place you can do it is in the special school your child already in.
Written, verbal and pictoral forms of communication as well as gestures and demonstrations are helpful. Annual counseling and referral on these issues to community agencies and programs is recommended.
