Hiring a nanny is usually the first time a parent becomes an employer. You are not buying a service. You are bringing a professional into your home to care for your child, paying a wage, and carrying legal obligations around taxes and overtime that most families have never dealt with.

The parents who end up with a great nanny tend to do two things well: they choose the person carefully, and they set up the professional structure around the job carefully. This guide walks through both, in the order you will face them.

First, confirm which kind of help you need

Many families search for a "nanny" when a different role fits the situation better. The labels matter because the skills, rates, and expectations differ:

  • Babysitter: occasional, short-term care, often evenings or weekends. No ongoing schedule.
  • Nanny: a regular, scheduled position, full time or part time, with the child as the focus of the job.
  • Newborn care specialist (NCS): a nanny with specific training in the first weeks and months of life, including feeding, soothing, and sleep habits. Families often bring in an NCS for nights during the newborn phase, then move to a general nanny.
  • Postpartum doula: support aimed mostly at the parent recovering from birth, with infant care included. Engagements are usually short.
  • Nanny share: two families employ one nanny together, splitting the cost and sharing the care.

If you are home with a newborn and what you actually need is overnight help so you can sleep, start your search with newborn care specialists and postpartum doulas rather than general nanny candidates. The vocabulary will lead you to better fits.

What a nanny costs in 2026

Two national surveys anchor the market right now. UrbanSitter's 2026 rate data puts the average booked nanny rate at $26.24 per hour, roughly $55,000 per year full time. Care.com's 2025 data, which skews toward posted starting rates, averages $20.68 per hour. A realistic planning range for a mid-career nanny is between those two numbers, adjusted for where you live and what the job involves:

  • Market: premium metros like San Francisco and Seattle run about 10 to 15 percent above the national average. Lower-cost metros like Dallas and San Antonio run roughly 25 to 30 percent below it.
  • Experience: PayScale data shows about a 20 percent spread between entry-level nannies and those with a decade or more in the field.
  • Additional children: expect to add $1 to $3 per hour for each child beyond the first.
  • Certifications: CPR and first aid training, newborn care credentials, and early childhood education background typically add $1 to $3 per hour.
  • Nanny shares: each family usually pays 60 to 75 percent of the solo rate, so two families together pay the nanny more than a single family would while each paying less.

A worked example: a mid-career nanny for one child in a high-cost metro at $24.50 per hour and 40 hours per week earns about $51,000 per year. Budget roughly 10 to 12 percent on top of wages for employer taxes and workers compensation, which brings the true annual cost to about $56,000 before any benefits. Our nanny rate calculator runs this math with your inputs, and our city-by-city rate pages cover 20 metros.

Two cost items that surprise first-time employers:

  • Overtime is mandatory. Under the Fair Labor Standards Act, live-out nannies are non-exempt employees. Hours beyond 40 in a week must be paid at 1.5x the regular rate, in every state.
  • Paid time off is standard. The industry norm is about two weeks of paid vacation, roughly five sick days, and six paid holidays. Nannies are paid for this time; it is part of the annual cost, not an extra.

Where to look, and what each channel gives you

  • Agencies pre-screen candidates, check references, and often guarantee a replacement if a placement fails within a set period. Placement fees commonly run from several thousand dollars up to a meaningful percentage of first-year wages. For newborn care or a first hire, the hand-holding is often worth it.
  • Online platforms like Care.com give you volume. You do the vetting yourself, which means reference calls, background checks, and interviews are all yours to run.
  • Word of mouth and local parent communities cost nothing and produce the strongest signal, since a referring family can tell you exactly how the nanny worked out. The tradeoff is a small pipeline.

Whichever channel you use, the vetting steps below stay the same.

How to vet a candidate

Call the references. Email is not enough. Speak with at least two former families and ask specific questions: how old were the children, what dates did the care cover, why did the position end, would you hire her again, and how did she handle a hard day. Vague enthusiasm is a weak signal; detailed answers about real situations are a strong one.

Run a background check. A standard screen includes a Social Security trace, county and national criminal searches, and the national sex offender registry. If the nanny will drive your child, add a motor vehicle record check.

Verify credentials. Ask to see the current CPR and first aid certification rather than accepting a mention of it. For infants, ask the candidate to walk you through safe sleep guidelines. A professional will answer without hesitation.

Interview questions that earn their time

The best interviews feel like conversations about the work, not interrogations. Questions worth asking:

About the work itself:

  • Walk me through a day you would plan for a child my daughter's age.
  • What does a good day look like at the end of it, for the child and for you?
  • Which ages have you cared for the most, and which do you prefer?

Judgment and safety:

  • A toddler is frustrated and escalating and your patience is running out. What do you do?
  • What would you want to know from me before you were alone with the baby?
  • How do you decide when something during the day is worth texting a parent about?

Logistics and expectations:

  • What did your last work agreement cover, and what would you want in writing this time?
  • What kind of check-in rhythm worked well with your last family?

Questions to skip. Do not ask about marital status, pregnancy, age, religion, or citizenship, and do not screen out candidates because they do not have children of their own. Years of experience with your child's age group predicts quality of care far better than parental status, and experienced nannies hear that question often enough to read it as a red flag about the employer. Childfree nannies make up a large share of the profession's most experienced caregivers.

Red flags run in both directions

Candidate red flags: arriving late to the interview with no notice, asking no questions about the job or the child, proposing payment under the table, references that cannot be reached, and an inability to describe what a typical day with a child looks like.

Employer red flags, meaning the things strong candidates walk away from: below-market pay, no written agreement, a job description that quietly grows from childcare into housekeeping without pay changes, and no guaranteed hours. The nannies most worth hiring have options. An offer that looks unprofessional to them will lose candidates you wanted.

The paid trial

Before committing, pay for a working trial of two to four hours at the full rate. Be home, but do not hover. No one works naturally with an audience, and what you want to observe is how the candidate relates to your child when you are not steering the interaction. A reasonable structure is the first hour together going over routines, then you step away for the rest.

If you use a nanny cam during a trial or afterward, disclose it. Visible, disclosed cameras are broadly accepted in the profession; hidden ones destroy trust when discovered. Note that audio recording is treated differently from video, and consent requirements vary by state, so check your state's rules before recording sound.

The work agreement

Put the job in writing before the first day. A work agreement is not about anticipating conflict; it is the reference document both of you consult when memory differs. It should cover:

  • Schedule, hourly rate, and the overtime rate
  • Guaranteed hours, meaning you pay the scheduled hours even when you take a day off or leave town
  • Paid time off, and how holidays are handled
  • The duties list, kept to childcare and child-related tasks unless you negotiate and pay for more
  • Sick policy for the nanny and for the child
  • Notice period for ending the arrangement, on both sides
  • How and when payment happens

Payroll and taxes, briefly

A nanny is a household employee, which means a W-2, not a 1099. IRS Publication 926 is the reference document: once wages pass a low annual threshold, you owe the employer share of Social Security and Medicare (7.65 percent) along with federal and state unemployment insurance, and many states require workers compensation coverage. Most families use a household payroll service to handle filings; the fees are modest compared with the cost of getting it wrong. Paying legally also gives your nanny a verifiable income history, which matters to professionals building a career.

Agree on communication before the first day

Daycare centers send parents a daily sheet: meals, naps, diapers, activities. Families that move from a center to a nanny often lose that structure without noticing, and what replaces it is a stream of texts during the workday. Each text pulls the nanny's attention away from your child, and each unanswered text raises a parent's anxiety. Left unplanned, this is where good arrangements quietly fray.

Decide deliberately what you want to know and when you want to know it, then put it in the work agreement. A workable clause looks like this:

Communication: [Name] will keep a daily log covering meals, naps, activities, and anything notable, shared with both parents as it happens or at the end of each day. Parents will save non-urgent questions for the evening handoff unless something needs attention right away.

This is also the arrangement nannies prefer. Clear expectations beat guessing what the parents want, and a written record of the day protects everyone.

The first ninety days

Schedule a check-in at 30 days and a more thorough review at 90, covering what is working, what needs adjusting, and whether the duties list still matches reality. Plan a raise cadence in the agreement; an annual cost-of-living review is the professional norm. And build a backup care plan before you need one, because a single-person childcare arrangement will eventually meet a sick day.

Treat the relationship as the professional arrangement it is: pay on time, honor the agreement, and address problems early. Families that are consistent on those basics are the ones whose nannies stay for years.
