How about a split shift nanny?
Some families want the nanny to come before and after school, which is problematic because it doubles the driving for your caregiver, and the morning shift is commonly only two hours long. We don’t recommend this scenario, because we want nannies have a four hour minimum each time they come to the home. All our requirements are geared to promote longevity in the relationship. If a split-shift is agreeable to the nanny, we recommend reimbursing her for mileage (55.5 per mile) for two of the trips, or using a family car.

What could a full-time Nanny/Manager Do?
Many of our families utilize a third solution, keeping their nanny full time and expanding her duties to include housekeeping, personal assisting or other home management chores. Part-time pay is generally higher than full time so for just a little more, you can have the advantage of full coverage. If you have a home business, she can sort mail, take on more of an assistant role, send out shipping, fill in for your school volunteer assignments or charities, and organize home or office, scrapbook, make travel arrangements, set appointments, pet and house sit when you’re out of town, deal with vendors, or cook dinner for the family. The key is to find out what she’s great at, then utilize her creative talents to make your life easier. You can pay a lower hourly rate, since she is full time, and she’ll tend to stay longer. You win because when you arrive home, all the pressing needs of the day will have been attended to and you need only enjoy the children and your peaceful and organized home.
