When You Travel Without the Kids: Overnight Care, the 10-Hour Rule, and Leaving Your Au Pair in Charge

Rachel and Dan had been invited to a wedding in Lisbon, three nights, and for the first time in years they were both going. Their au pair, Lucía, had been with the family for five months. The kids adored her. The plan seemed obvious: Lucía stays, the kids sleep in their own beds, a neighbour is "on call" if anything goes wrong.

Two weeks before the flight, Rachel mentioned the plan to their local childcare consultant, almost as an afterthought. The answer was not a no. It was a list of questions. Who is in the house at night? How many hours is Lucía on duty on Saturday? Which of the 45 weekly hours are left once Thursday and Friday are counted? Does anyone besides Lucía know where the kids' medical details are?

Rachel had no answers. Nothing about the trip was reckless, and Lucía was perfectly capable. The gap was that a weekend away does not fit into the hour rules the way an ordinary week does, and nobody had done the maths.

This guide does that maths. It covers what the rules actually say about leaving an au pair in charge, why a multi-night trip almost always needs a second adult, and how to write the handover that makes the days away uneventful.

🇺🇸 This guide covers the U.S. J-1 au pair program. The hour limits come from the U.S. Department of State (22 CFR 62.31). Rules for au pairs in Germany, the UK or elsewhere differ. Your sponsor's handbook is the authority for your placement, and sponsors differ on overnight care, so confirm with your local consultant before you book anything.

What the Rules Actually Say About Parents Being Away

The honest starting point is an uncomfortable one: the federal regulation says nothing about overnight care or parents travelling. It sets limits on hours and rest, and a few rules about when a responsible adult must be home. Everything else comes from sponsors.

What the Regulation Does Say

Section 62.31 is short on this topic. These are the parts that bear on a trip:

• Hours: The written agreement between you and the au pair must limit childcare to no more than 10 hours per day and 45 hours per week (30 hours per week for EduCare). Sponsors must also require that au pairs do not work more than that (22 CFR 62.31(e)(5) and (j)(2)).
• Rest: At least 1.5 days off per week, plus one complete weekend off each month, and two weeks of paid vacation (22 CFR 62.31(j)).
• Newborns: A family with a child under three months must have a parent or other responsible adult present (22 CFR 62.31(e)(2)).
• First days: A parent or other responsible adult must stay in the home for the first three days after the au pair arrives (22 CFR 62.31(e)(1)).

Read as a whole, section 62.31 has no sentence that says "an au pair may not be the only adult overnight," and none that says she may. The limits are on hours, and the question of what counts as an hour at 2 a.m. is left to the sponsors.

What Sponsors Add

Sponsors fill that gap, and they fill it differently. Au Pair in America's host family handbook is a useful example because it is explicit. Its list of things an au pair should not be asked to do includes:

• Sole responsibility for an extended period for weekend or business travel by host parents. A responsible adult must be in the home, and the au pair must not be on duty for more than 10 hours a day.
• Being responsible for the household or family pets while parents are absent.
• Caring for a child under three months unless another responsible adult is present.

The same handbook tells families that if they will be away overnight, a parent must arrange for an alternate responsible parent to be in the house when the coverage time exceeds the 10-hour daily limit, and asks them to tell the community counselor when the au pair and children will be at home with another responsible adult.

Other sponsors word it differently, and some are stricter. A host mother in a 2013 AuPairMom thread quoted her agency contract as strictly forbidding leaving the children alone with the au pair overnight, while other commenters said their agencies did not prohibit it. That thread is community experience, not official guidance. Its useful lesson is the one the commenters agreed on: read your own contract.

Key takeaway: The regulation limits hours; your sponsor decides what an overnight stretch looks like. Ask in writing before you plan the trip, not after you have booked the flights.

Why the Hour Maths Rarely Works for a Whole Weekend

Even if your sponsor allows a parents-away stretch, the numbers decide how much of it Lucía can carry. The cleanest way to see it is to count waking hours first and nights second.

Start With the Day

The 10-hour cap is a ceiling per day. Suppose your children are up at 6:30 and in bed by 20:30. That is 14 hours of awake time to cover. Under the 10-hour rule, one au pair can cover ten of them. The other four belong to someone else, every day of the trip, before anyone has thought about the night.

Our guide to counting au pair hours explains how the 10-hour day and the 45-hour week interact. A trip makes the interaction visible, because the extra hours you are asking for land on days that are normally parent days.

The Night Question

Sleeping hours are where families and sponsors disagree, and where the regulation does not help. Our reading, and the one we suggest planning around, is the conservative one: if your au pair is the only adult responsible for the children overnight, treat the night as working time unless your sponsor tells you in writing that it is not. That is the position behind the handbook language above, which asks for a second responsible adult in the house rather than counting sleep hours as free.

The practical effect is simple. A night of sole responsibility does not fit inside a 10-hour day that also contains the morning routine and bedtime. A second adult sleeping in the house solves it.

The Week Around the Trip

Then comes the weekly cap. This is where the carefully planned trip usually breaks. Here is an example for Lucía, whose regular weekday shift is 8 hours Monday to Thursday, with Rachel and Dan away from Friday afternoon until Sunday evening:

That is 13 hours over the 45-hour cap, before counting the days-off rule. Lucía would also have no weekend free, and the rule is 1.5 days off per week plus one complete weekend a month.

Key takeaway: The trip is not the problem. The week around the trip is. If the au pair carries the weekend, the Monday-to-Thursday shifts have to shrink, and her days off have to move to earlier in the week.

Three Ways to Make the Numbers Fit

1. Shrink the shifts before the trip. Cut Monday to Thursday to 6 hours each (24 total) and 21 hours remain under the cap for Friday to Sunday, so the backup adult takes the rest of the weekend. Be explicit that this is a trade, and write it down.
2. Bring in a second adult for the weekend blocks. A grandparent, an aunt, a trusted friend. They take the morning or the bedtime, and they sleep over.
3. Move the kids. If the children spend the weekend with relatives, your au pair is off duty and can have the days to herself. Check the vacation rules before you ask her to treat it as vacation days. That is a conversation, not an assumption.

You can try your own numbers in the schedule checker: enter the trip week, and it shows which days break the rules.

The Second Adult: Who Qualifies and What They Actually Do

"Another responsible adult" is the phrase the rules and handbooks use, and none of them define it. This is the single most useful thing to ask your local consultant, because the answer is a sponsor decision.

Who to Ask

Think about the adults your children already know:

• A grandparent or other relative who has stayed over before
• A close friend or neighbour the children trust, who has the time
• A paid sitter or nanny you have used regularly

Whoever it is, they need to be someone the children would go to in the night, not a name on a list. A neighbour who is "on call" two streets away is a contact, not a second adult in the house.

What the Second Adult Does

The role is narrower than "babysitter," and spelling it out avoids friction:

• Sleeps in the house and is the adult the children find if they wake up
• Covers the hours above the au pair's 10 (see the table above), typically early morning or bedtime
• Holds the decisions that need a parent's authority, such as a doctor's visit, a school phone call or a permission slip
• Knows the house well enough that the au pair is not teaching them where the fuse box is

Key takeaway: A second adult is not a vote of no confidence. It is the thing that lets your au pair do her job inside her hours, and lets someone with authority make the call if a child needs a doctor at 3 a.m.

Preparing Your Au Pair: Talk Before You Book

The conversation with your au pair matters as much as the hour maths. She should hear about the trip as a proposal, not as a notice.

Open with the dates and the shape of it: "We'd like to go away from Friday afternoon to Sunday evening. Here is how we think we can cover it, and here is what we'd change in your week." Then ask her:

1. Is she comfortable with it? Being the senior adult in the house, even with a backup, is a bigger responsibility than a normal day. She is allowed to say it is too much.
2. Which blocks does she prefer? Some au pairs like early mornings, others prefer evenings.
3. What does she need to know? The answers become the handover document.

Our guide to babysitting beyond regular hours covers the "ask first and accept a no" rule. It applies here with more force, because the trip is planned in advance and there is no emergency to hide behind.

Tell the au pair also what she is not responsible for. The Au Pair in America handbook, for example, lists responsibility for the household or family pets while parents are away among the things an au pair should not be asked to take on. If the dog needs a sitter, arrange one.

The Handover Document

A parents-away stretch is the moment a written handover earns its keep. Everything you would normally say out loud, because you are in the room, now has to be on paper. Our guide to child profiles shows the kind of detail that helps; for a trip you need a tighter, single-document version.

What Goes In

• Contacts: Both parents' mobile numbers, the hotel or venue, the second adult, one local friend, your pediatrician and the nearest urgent care. The emergency contacts guide covers who to include.
• Medical: Allergies, medications and doses, inhaler locations, insurance details. Our guide to putting allergies and medications in writing covers the format.
• Authorization: A signed emergency medical authorization, so that if a parent cannot be reached, the adult with the child can give a doctor the information and consent the clinic asks for. The Au Pair in America handbook, for example, tells host families to complete an emergency medical authorization for the au pair to hold in case she cannot reach them. Ask your pediatrician what form the clinic prefers.
• Routines: Wake-up, school run, meals, screen time, bedtime, the song, the stuffed animal. Write the order, not just the times.
• The week's calendar: School pickups, practices, playdates, anything that needs a car seat.
• House basics: Alarm codes, where the spare key is, how the heating works.
• Decision rules: What the au pair can decide alone, what she should text you about, and what she should call about.

A practical test: Hand the document to someone who has never been in your house and ask them to run Saturday from it. Every question they ask is a missing line.

Make It Easy to Find

Print one copy for the fridge and put one in the shared place your family already uses. The emergency card tool makes a fridge sheet and wallet card from details you type once.

If your family uses AuPairSync, the trip can live in the shared calendar with each coverage block assigned to a named adult, so nobody has to ask who has Saturday morning. The medical authorization and insurance details can sit next to the contacts in document storage, where the au pair and second adult can open them from a phone.

Telling Your Sponsor

Do this early, and in writing. Send your local consultant:

• The dates of the trip
• Who the second adult is and when they will be in the house
• How you can be reached
• The hours schedule you have worked out for the week

Au Pair in America's handbook also asks host families to make sure their counselor knows how they can be reached while they are away, so the counselor can contact the au pair in an emergency. Even where your sponsor does not ask, the message protects everyone. It shows the hours were planned, and it puts a sponsor decision on record before the trip, when it can still change your plans.

While You Are Away

Plan the check-ins. A trip with no contact makes the au pair nervous, and one with constant messages makes her feel watched.

• One scheduled check-in a day, at a time that works across time zones, with a short summary from her
• One thread for everything, not a mix of texts, emails and voice notes
• A clear emergency channel, so she knows when to call instead of write
• Reachability windows: a wedding is not the moment to discover your phone is in a coat check

When you come back, thank her properly, and look at the hours she worked. If the trip pushed her above her usual load, give the time back that week. A small, visible gesture matters more here than a gift.

A Checklist Before You Go

1. Confirm with your sponsor what overnight care means under your agreement, in writing.
2. Name the second adult and agree which hours they cover and where they sleep.
3. Do the maths for the whole week, including the 45-hour cap and the 1.5 days off.
4. Ask your au pair, as a question, not as an announcement.
5. Write the handover: contacts, medical, routines, calendar, house basics.
6. Sign the medical authorization and leave it where the adults in the house can find it.
7. Tell your sponsor how to reach you and who will be in the home.
8. Set the check-in rhythm and the emergency channel.

If your au pair is also the person you would normally call when someone else is sick, read our sick day and backup childcare guide too. The backup plan you build for a trip is the same one you will need on an ordinary Thursday morning.

The Bigger Picture

A trip without the children is one of the few moments when a family's trust in its au pair is visible to everyone, including the children. Done well, it tells them that their au pair is a real part of the household and that the adults around them can be counted on, in person or from a distance.

The structure is what makes it possible. A second adult in the house, hours that add up, a document anyone can read, and a conversation that started with a question. None of that takes away from the trust. It lets the trust stay small and easy, so that the only thing you have to think about in Lisbon is the wedding.
