I visited The Autism Show at ExCel this weekend.

There were many stalls showing their products help and support children and adult with special needs.
I thought this coloured gel mat was quite interesting.

There were also many talks as well.
Damian Milton, independent autism consultant, talked about the ways and theories of intervention for children with autism. He mentioned that it could become dangerous if the person, who is intervening a child, worships one particular therapy and start blaming on their parents for not making a real progress.

In the end, the most important thing is to know the child and how well you could tailor the intervention to suit their need.
