Yes don't forget that the time off can be shared between maternity/paternity leave. In some cases the dad takes the year off or at least several months to help run the daycare - mostly to be the one awake while mom naps/feeds baby and heals as needed.

Be prepare that the longer you take off the likelihood of your families returning to your daycare when you reopen is reduced meaning once they are settled at the new daycare they may choose to stay there and you will be needing to budget to look for new families.
