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.

A little bit about me
Hello! My name is Madison, and I’m 19 years old. I’m a caring, patient, and dependable person who has always enjoyed working with children. I’ve been babysitting and caring for my siblings for the past 6 years, which has given me a lot of hands-on experience with children and taught me how to be responsible, patient, and attentive to their needs.
I also serve in children’s ministry at my church, where I get to spend time with and care for children in a fun, encouraging, and positive environment. I really enjoy getting to know each child’s personality and finding activities that they enjoy, whether that’s playing, doing crafts, reading, or simply spending time together.
I understand how important it is for parents to have someone they can trust with their children, and I strive to be dependable, respectful, and communicative with every family I work with. I’d love the opportunity to get to know your family and be someone you can feel comfortable relying on for childcare!
