I'm an soon to be self employed lone parent of dd aged 2, I will need two evenings a week and every 2nd saturday child care and have space for someone to live in. My friend who lives a few streets away needs help doing school runs and a couple of other bits for of dc 4&6. Au pair would never have 3 dc at same time as I would continue to use nursery for day time care. Would this work or is it too much?
