We have a brilliant nanny 3 days a week. She was also working 1 day for another family, which has just fallen through. She wants 40 hours over 4 days. I've found another family who want 8 hours plus 2 hours babysitting, and offered her a raise so we pay her for 30 hours though we use about 26, but she says she finds it hard working for 2 families (even though we're friends) and wants time with awake children, not babysitting. This is rural Kent and I don't think she'll find what she wants, but how can we stop her looking?
