"We have created rods for our own back. Children need time to be bored."
Mrs Perry, who took a seven-year break from her career in management consulting when her children were young, said mothers were often behind youngsters' cosseting because their own careers struggle when they start a family.
She said: "A lot of it is women who, because it is difficult to get on, subjugate their own ambition into their kids.
"That makes it harder when they get to university and realise they haven't got a mother to help them with their homework, watching their every move.
"We've all done it. Now, I just can't, so I don't, and I think they're probably better off as a result."
