5 Checkpoints to Evaluate If Your Nanny Is Truly Trustworthy

The short answer: the three keys to identifying a truly trustworthy nanny are verifying her background, observing how she interacts with your child, and assessing her ability to handle emergencies. Using a reputable placement agency makes it far easier to cover all three — efficiently and reliably.

Because you're entrusting someone with your child's care, "Can I really trust this person?" is naturally the most pressing question on your mind. At HelloNanny, we've built up extensive know-how through over 300 successful placements. Here are the five checkpoints — and the traits they share — that define a truly trustworthy nanny.

1

Checkpoint 1: Work History and References

Always ask about previous employers and how long she worked with each family. Frequent, short-term job changes can be a red flag. Ideally, ask for a written recommendation letter from a former employer.

At HelloNanny, we interview every registered candidate in depth — including how many children they've cared for and at what ages — so you receive detailed, verified background information from the start.

In Thailand, criminal background certificates can be obtained from local police stations. Any reputable agency should carry out identity checks at the point of registration. Make sure to keep a copy of the candidate's ID card on file.

All 2,000+ registered staff at HelloNanny have undergone identity verification.

Checkpoint 3: How She Interacts With Your Child

During the interview — or even in a brief online video call — observe how the candidate engages with your child. Look for:

• Tone of voice: Is she gentle and warm when speaking to the child?
• Eye level: Does she crouch down to meet the child at their height?
• Natural warmth: Does she smile genuinely, or does it feel forced?
• Your child's reaction: Does your child seem at ease? Do they naturally gravitate toward her?

HelloNanny's pre-screening process identifies candidates who are likely to be a good fit for your family, which means fewer interviews before you find the right person.

Ask scenario-based questions such as: "What would you do if my child suddenly developed a fever?" or "What if they fell and got hurt?"

Look for candidates who can:

• Describe a clear, calm course of action step by step
• Demonstrate knowledge of CPR or basic first aid
• Understand when and how to notify the parents
• Make sound judgment calls about when a hospital visit is necessary

Checkpoint 5: Communication Skills

It's not just about language ability — what matters most is whether she's the kind of person who keeps you informed.

• If something goes wrong, will she tell you proactively — or stay quiet?
• Ask: "What would you do if you weren't sure how to handle something?" — and watch her response.
• Is she comfortable communicating via LINE or messaging apps?

Frequently Asked Questions

How many interviews will I need to do?

Because we conduct detailed pre-screening and narrow down candidates carefully, most families find the right nanny after just 1 to 2 interviews.

Are the nanny's background and identity really verified?

Yes. We conduct ID card verification and reference checks with previous employers for all registered staff. Criminal background checks are also carried out where possible.

What happens if the nanny isn't a good fit after placement?

We follow up one week after the start date to check in with both parties. If the match isn't working, we'll arrange a replacement — and can typically introduce a new candidate within 3 days.
