Common Nanny Share Mistakes to Avoid
Pursuing a nanny share is one of the financially sound childcare decisions that a San Francisco family can make. You get personalized in-home care at a lower cost than hiring a private nanny, your child gets a built-in playmate and the social benefits of a small group setting, and your nanny earns a higher overall wage. But the arrangement only works when it’s set up correctly from the start. Here’s a quick guide from SF Nannies that covers the most common mistakes families make when entering a nanny share and how to avoid them.
1. Skipping the Compatibility Conversation
Finding a local family who also needs childcare on a similar schedule is a great start, but it’s not enough. Plenty of nanny shares fall apart because the families never took the time to discuss the details of how they actually want their children raised during the day.
Before committing to another family, we recommend sitting down and talking through the things that matter most. Discipline approach, screen time limits, food and dietary preferences, nap schedules, vaccination status and communication style are all areas where misalignment creates friction fast. Think of this conversation as a mutual interview. Ultimately, you’re choosing a nearby family whose values and routines will shape your child’s daily experience.
2. Not Putting Everything in Writing
It’s surprisingly common for nanny share families to operate on verbal agreements. Everything feels great at the beginning, so a handshake seems like enough. But the moment a disagreement comes up around scheduling or responsibilities or time off, the lack of documentation makes it exponentially harder to resolve.
A nanny share contract in San Francisco should cover the hourly rate, weekly schedule, guaranteed hours, overtime policy, paid time off, sick day procedures, holiday pay, household responsibilities and termination terms. In most cases, each family should also have a separate contract with the nanny rather than one shared agreement. This protects everyone involved and keeps expectations clear if one family eventually needs to leave the arrangement.
3. Splitting the Nanny’s Rate 50/50
This is one of the most damaging mistakes families make, and it often comes from a misunderstanding of how nanny share compensation should work. Some families assume they should simply split their nanny’s solo rate down the middle, 50/50. That math shortchanges the in-home nanny significantly.
With nanny shares, the industry standard is the two-thirds rule. Each family pays approximately two-thirds of what they would pay for a private nanny. The nanny ends up earning more than a solo position, which is fair given that they’re caring for additional children, managing two sets of expectations and coordinating between two households. Underpaying leads to burnout and turnover, which disrupts care for everyone.
4. Not Having a Plan for Sick Days
Ask any experienced nanny share family what causes the most friction, and sick days will almost certainly be near the top of the list. When one child is sick, the questions pile up quickly. Does the nanny still come? Does the healthy child still attend? Who pays when one family keeps their child home?
These situations are completely normal, but they become stressful when there’s no agreed-upon policy. We recommend to decide upfront how you’ll handle both child illness and nanny illness. Put the plan in the contract so everyone knows what to expect when the inevitable runny nose arrives.
5. Failing to Communicate Openly
Small frustrations have a way of snowballing when families avoid direct communication with each other or with the nanny. A minor scheduling change or a household preference that goes unspoken can build into real resentment over time.
At SF Nannies, we recommend setting up a regular cadence for check-ins, whether that’s a quick weekly text thread, a shared daily log or a monthly sit-down between both families and the nanny. Address concerns early before they become conflicts. In our experience, the nanny shares that last the longest are the ones where everyone feels comfortable speaking up.
