I know I'm a couple of pages behind now but I wanted to answer Duchesses question.
£3.60/hour (per child) is not what I earn in wages. It's my gross income. From that I have to take out all my expenses (premesis, gas, electric, water, council tax, food, travel, outings, toys and resources, cleaning supplies, toiletries, training costs, Ofsted fees and insurance).
I could earn a fair wage easier if I stayed at home all day and did nothing but I offer quality childcare. We go out everyday. I provide all food. My fees are all inclusive.
So my actual wage at the end of the day is considerably less than £3.60/hour/child.
Also, the £3.60 is the same rate whereever you go in the country, but this does not reflect childcare costs. Most nurseries in my area charge around £4.20/hour. I don't know how they could get round this and still be fair tbh.
