Is 25 the new cut-off point for adulthood?

Lucy Wallis:

“The idea that suddenly at 18 you’re an adult just doesn’t quite ring true,” says child psychologist Laverne Antrobus, who works at London’s Tavistock Clinic.
“My experience of young people is that they still need quite a considerable amount of support and help beyond that age.”
Child psychologists are being given a new directive which is that the age range they work with is increasing from 0-18 to 0-25.
“We are becoming much more aware and appreciating development beyond [the age of 18] and I think it’s a really good initiative,” says Antrobus, who believes we often rush through childhood, wanting our youngsters to achieve key milestones very quickly.
