Tips to find a great nanny without overpaying

• Be flexible on experience. Some of the best nannies on the platform have 3–5 years on the job and charge meaningfully less than experienced nannies with 10+ years. References matter more than years.
• Consider a share. If your kids are similar ages and you live near another family, a share is the single biggest cost reduction available without compromising on care.
• Be specific about hours upfront. Most nannies will take a slightly lower rate for a guaranteed steady schedule than for a higher-rate, unpredictable one.
• Bundle benefits thoughtfully. Two weeks PTO, a health stipend, transit passes, education assistance, or an annual raise commitment can help close the gap with families offering a higher hourly rate.
• Match rate to responsibilities. A higher rate often makes sense once you add cooking, errands, or driving. Don't compare apples to oranges across listings.
