My 3yo attends a preschool with childminder wraparound. We are both doctors. Preschool have said you need two key worker parents to stay - there is no-one else with two key worker parents in all nursery. Am terrified how this will be. Staff we don't know on a rota, no continuity, no other children that he knows. God I'm terrified for him. Preschool teachers please tell me this will be ok?
