I work shifts and childcare is a bit of a minefield because one week I might need every day and the following week nothing. I have been relying on friends to help out on the mornings when I need to leave early. Now I have found a childminder.She is not an official one but works in the after school club so I know she is CRB checked etc etc. She will do 3 mornings a week whenever I need her to. I have 3 children. Ages 5, 9 & 10. They will be with her for one hour during which she will walk them to school 5 mins away. All seems perfect. However when I mentioned money she said I should suggest something which seems fair. I am stumped. Haven't got a clue what the going rate is but I am living on a student bursary so can't afford to be too generous. But at same time want it to be worth her while or else why would she do it for me! Any suggestions?
