Oh ffs, not this old chestnut again.
A childminder who looks after one child at a time (or who works for only one family) is not a childminder, she's a nanny. And she would probably earn more then a cleaner for doing so.
A childminder looks after several children at once. So she also earns more than a cleaner.
A cleaner works 2-3 hours a week for a family, getting paid around £20-£30 for doing so.
A childminder, per full-time charge, works say 9 hours a day, 5 days a week, so that's 45 hours a week, at £5 an hour, so that's £225 a week.
If childcare cost £10 an hour not many would be able to afford it. It's a pointless argument.
I get so pissed off with posts implying that people value a clean house more than their children simply because of the difference in hourly rate.
I pay £80 a month on my cleaner. £1500 on childcare. Does that answer your question in very simple terms?
