In my contract, I state that I reserve the right to vacate spots in order "to care for my own family". This is stated relatively vaguely, in order to accommodate reducing numbers when i eventually have my own baby, or to look after children in my family (my own future children/nephews/nieces/brothers/sisters). I did not state how I would choose which kids would be asked to leave. I used to look after my nephew, until my second nephew was born, and now I want to look after both nephews again now that they need daycare. How do I pick which kids keep? Part time? Full time? Longest attending kids? Best parent-provider relationship? Easiest kid?
