Hiring a full-time nanny is one of the biggest decisions you'll make as a parent—this person will spend more waking hours with your child than you do. Getting the vetting process right takes time and diligence, but it's the only way to feel confident leaving your child in someone's care. Here's exactly what to check before bringing someone into your home.
Start with Background and Reference Checks
Run a comprehensive background check through a reputable service—this typically costs $50–$150 and covers criminal history, sex offender registries, and driving records. Don't skip this step or rely on the nanny's word; use services like Checkr, Accurate Background, or local law enforcement databases specific to your state.
Call at least three personal and professional references. Ask previous employers or families specific questions: How long did the nanny work for you? Why did they leave? How did they handle discipline, emergencies, or conflicts? Listen for hesitation or vague answers—legitimate references should speak clearly about their experience.
Verify Certifications and Training
A full-time nanny should hold current CPR and First Aid certification (renewal typically every 2 years, costing $60–$150). Check that credentials are active and haven't expired. Ask which certifications they hold beyond the basics—Nanny training programs like the International Nanny Association or local childcare courses show commitment to professional development.
Request proof of any coursework in child development, nutrition, or special needs care if relevant to your family's needs. These aren't always required, but they signal a thoughtful, invested caregiver.
Assess Compatibility and Parenting Philosophy
Schedule multiple interviews—at least two—to gauge whether the nanny's approach to childcare aligns with yours. Discuss specific scenarios: How would you handle a tantrum in a store? What's your view on screen time? How do you approach potty training or discipline?
Pay attention to red flags like:
- Dismissing your preferences as "old-fashioned" or "overprotective"
- Vague answers about handling behavioral issues
- Reluctance to provide references
- Unwillingness to discuss rates or expectations upfront
- No experience with your child's age group or any special needs
A good fit means someone who respects your family's values while bringing their own expertise and warmth.
Evaluate Experience and Specialization
Ask directly: How many years have you worked as a full-time nanny? How many families? What age groups? A nanny with 5+ years of full-time experience managing multiple children will handle chaos differently than someone fresh into the role.
If your child has specific needs—allergies, developmental delays, behavioral challenges, or language exposure—verify the nanny has demonstrated experience. Don't assume; ask for concrete examples of how they've managed similar situations.
Discuss Rates and Employment Terms
Full-time nanny rates vary significantly by location and experience. In major urban areas (New York, San Francisco, Boston), expect $50,000–$80,000 annually; in suburban or lower-cost areas, $30,000–$50,000 is more typical. Clarify whether you're paying gross (you handle taxes) or net (nanny pays taxes), and agree on overtime, vacation days, sick leave, and benefits upfront.
Put everything in writing—a simple employment agreement covering hours, pay schedule, responsibilities, and termination terms protects both of you. Many families use nanny agency templates or consult an employment attorney for this ($200–$500 investment upfront prevents costly disputes later).
Trial Period and Ongoing Check-ins
Propose a 2–4 week trial period before making it permanent. This gives you time to observe how the nanny interacts with your child, manages your home, and handles real situations. Some families use nanny cameras during this phase for additional peace of mind.
Schedule regular check-ins—monthly conversations in the first year, then quarterly. Ask your child open-ended questions about their day. Watch for behavioral changes or concerning comments.
