She is a friend and will have my DD2 from 9am until 6pm 2 days a week. She isn't registered but has childminded before, has a DD the same age as mine DD2, a 2 yr old and a 12 yr old. She offered to have DD2 for me on those 2 days when I go back to work. I like her a lot, trust her and feel very happy and lucky. We'll start off on a months trail basis so she can back out if it's too much.
How much is fair to pay her?
TIA.
