Parents need to make some hard calls if they want to help prepare their teenagers for independence away from home, says a young adult guru.
Seven Sharp reported the average age young adults plan to leave their parents' home is 27, while parents rarely give their teens a lot more responsibility and freedom to prepare them to fly the coop.
"They're treating their parents like an unpaid servant and a banker," said Yvonne Godfrey, who runs courses to help 16 to 24-year-olds truly grow up.
"The number of parents who are changing the sheets on a 16-year old's bed - absolutely frightening.
"They have to be able to run a household. They have to be able to take care of themselves. They can't still have their parents making doctors appointments for them."
Ms Godfrey, who was a host parent on reality TV show The World's Strictest Parents, said young people are a product of what has been expected of them.
"Mostly I find that they're micromanaged. But they're not expected to do a lot. So it's this mentality that they're children."
She said parents "have to do the hard yards, they have to make the hard calls. Be a parent not a friend. You can't be friend until they're no longer financially reliant on you, physically reliant on you or emotionally reliant on you".
I am an ATM machine"

However, it seems some parents of young adults Seven Sharp spoke to are not buying into the expert's message.
"I just love my son so I do anything for him anyway. But yeah, I am pretty much his slave. I'm soft, but he's our youngest and even though he's 21 he's still my little baby," one mum said.
Another said: I love having the kids at home. Two are working but you've still got to help them out. The other one's doing a course and she's fully funded by me. So I am an ATM machine."
A dad said: "I'm very happy to bankroll my daughter. She's at the stage in life where she needs that support and I think it'll stand her in good stead going forward."
