is a classic sign of FASD described by Clarren, Malbin and Streissguth. A person with FASD will simultaneously exhibit behaviours common to people of different ages. For example, someone with FASD might be 18 years of age, sound like a 22 year old (expressive language), act like a 6 year old in a social and moral sense, read like a young teen and understand time and money at about the same level as a 12 year old. People with FASD tend to catch up to themselves as much as they are going to by their early to mid-thirties.
