 As a result of this, in 1946 Judy wrote a letter to Nursery World Magazine asking all parents also having difficulties with a “backward child” to get in contact.There was a huge response with over 1,000 parents responding and consequently a group was formed of parents who pleaded their cause to local health and education authorities.This group grew into the Association of Parents of Backward Children (APBC), the forerunner of Mencap.
