My daughter was intrigued by a request for volunteers to do some medical research on Autism and took her daughter, Millie, aged 5 months, along to participate. It involved wearing a skull cap with lots of electrodes on it and then watching a TV screen with various activities going on. Brain activity was then observed on a monitor. Millie was not upset at all.

She will return at age 9 months for further assessments and hopefully the research will give some insights into Autism.
