Yep. We charged dd at 18 years.
She didn't want to go to uni and wanted to work. So she contributed to the house hold like all the other working adults. £100 a month.
It was a while ago before we owned our buisnsness so the extra income was welcome. It also helped her budget and not take the house/us for granted. She has bought her own apartment now.
We have two younger DC and are in a very different financial situation where we don't need the money and I know it will become a problem as Dh won't want them contribute to the house hold where as I will.
My point is we are supposed to be nurturing children to be responsible adults not adult babies that get pampered and refuse to fly the nest
