Early intervention is better. But i feel better u stay back in germany and get the therapies done. Dont keep high expectations of therapies and treatment here. i am mother of 16 year old son. He has ADHD and Epilepsy problem. I only teach him at home. none of the school gave admission becoz of the hyperactivity problem. Special schools are pathetic.
Mother is the medicine for all. Have patience. Try out various therapies at home only. Like set a target and work on it. For example, if u want to teach ur child to brush teeth. Set a target of 15 days or so and work on it. The child has to mingle with the kids. So everyday 1hour see that he spends time among children. Give ur son a home based school experience.
I am not disappointing u, ur plans of coming to india for therapies.
Try NIMHANS banglore for therapies.
