What drives the price

Most St. Louis families pay somewhere in the $14–$25/hour range. Where a given family lands depends on a handful of factors. Three of them drive most of the spread.

Experience

Experience is one of the biggest levers on a part-time nanny's rate.

Nannies with 10+ years, or specialty skills like newborn care or multiple languages, typically command the highest hourly rates.

Number of kids

One child is the baseline. Each additional child usually adds $1–$2/hour. Twins and infants tend toward the high end.

Tips to find a great part-time nanny without overpaying

Be flexible on experience. Some of the best part-time nannies on the platform have 3–5 years on the job and charge meaningfully less than experienced part-time 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 part-time 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.
