A rotational nanny (ROTA nanny) is a live-in nanny who provides care for a pre-determined amount of time – usually one-to-two-weeks – before having a non-working day. When that time is up, the nanny gets an extended period of time off, usually at least 7 days. Rather than the family going without a nanny during that time, another ROTA nanny takes over in their absence. These two nannies each live in the home during the time they’re working and will switch off on that rotating system.
