I have two brothers who will be with me before or after school during the week, depending on the hours the mum works (dad is out of the picture completely). So maybe two days a week I will have them before school and the other 3 after school. Sometimes it might only be 3 or 4 days a week.
I don't want to shoot myself in the foot as I have done before by leaving it open ended: I think I should have a minimum retainer per week to make it worth my while and to guarantee the place for the children.
Does anyone have any suggestions as to how I can word it? Does my post even make sense??
