Claire had done everything right, or so she thought. Lucía's year was ending in August, the new au pair Hanna was booked to arrive four days later, and Claire had spent three evenings getting Lucía to write down the school runs, the swimming schedule and where the spare key lived. The handover document was eleven pages long. She was quietly proud of it.
What she hadn't planned was the children. Mia, who was seven, found out Lucía was leaving when she saw the suitcase in the hallway. Leo, who was four, didn't really understand until the morning Lucía was gone and a stranger was standing in the kitchen.
On Hanna's first night, Leo refused to let her into his room. "You don't do it right," he screamed, and he was correct: Lucía had sung a Spanish song, turned the star lamp on before the big light went off, and left the door open exactly a hand's width. Nobody had written any of that down. Mia was politely helpful all week and then started wetting the bed again.
None of this was anyone's fault. The handover covered everything the adults needed. It just skipped the people who were losing the most.
Your kids are losing someone too
For you, an au pair changeover is a logistics problem with a deadline. For your children, it is the loss of someone who did bedtime for a year. A child adjusting to a new au pair is not adjusting to new staff. They are grieving a person who was present for hundreds of breakfasts, bath times and scraped knees, and then being asked to accept a replacement they didn't choose.
Adults tend to underestimate this for a simple reason: we know the arrangement was always temporary. Children don't carry that frame. To a four-year-old, the au pair was simply part of home, like the kitchen table.
What the loss looks like at different ages
Children rarely say "I am sad that Lucía is leaving." The grief comes out sideways, and it looks different depending on age.
| Age | What they understand | How the loss tends to show |
|---|---|---|
| Under 3 | Almost nothing about why, a lot about who is missing | Clinginess to parents, disrupted sleep, searching for the person |
| 3–5 | That someone is going, not what "going home" means | Regression (toilet, sleep, baby talk), anger at the new au pair, "you're not her" |
| 6–9 | The reason, and that it is permanent | Worry, questions, bargaining ("can she come back at Christmas?"), sudden good behaviour that cracks later |
| 10+ | Everything, and they may pretend not to care | Withdrawal, coolness towards the new au pair, occasional unexpected tears |
Key takeaway: A child who is rude to the new au pair in week one is usually not rejecting that person. They are protesting a loss nobody helped them process.
The good news is that most of this is predictable, and a lot of it is preventable. The families who get through a changeover smoothly are rarely the lucky ones. They are the ones who treated the children's side as part of the plan.
When and how to tell your children
The instinct is to protect children by telling them late. It almost always backfires. A child who learns about a departure from a suitcase in the hallway gets the loss and the shock at the same time, with no runway to prepare.
Timing by age
- Under 3: about one week before. Longer than that means nothing to them, and the waiting just becomes anxiety.
- 3–5: two to three weeks before, using concrete markers instead of dates ("after your birthday party", "when the leaves start falling").
- 6–9: four to six weeks before, as soon as the date is certain.
- 10+: as soon as you know. Older children who find out late feel lied to, and they are not wrong.
The one firm rule for every age: tell them before the decision could leak. Children overhear phone calls, notice flight confirmations on the kitchen table and read the mood in the house far better than adults assume.
What to actually say
Keep it short, true and repeated. Children process big news in small pieces, and they will ask the same question many times over the following weeks. That repetition is normal, not a sign that you explained it badly.
- Name the fact plainly: "Lucía's au pair year is ending. In August she's flying home to Spain."
- Give the real reason, at their level: "Au pairs come for one year to learn our language and live with a family, and then they go back to their own family and their studies."
- Say that it is okay to be sad: "It's okay to feel sad about it. We're sad too."
- Tell them what stays the same: "You'll still have the same bedroom, the same school and the same bedtime song."
- Tell them what happens next: "A new au pair called Hanna is coming. We'll show you her photo."
Key takeaway: Children cope better with sad news than with confusing news. Short, honest and repeated beats a single perfect conversation.
What not to say
- "She has to leave because of work" (when that isn't true): children remember invented reasons, and they unravel.
- "She'll visit really soon": unless a date is booked, this is a promise the child will hold you to for months.
- "You'll love the new one even more": this turns love into a competition and makes the child feel disloyal for liking Hanna.
- "Don't cry, it's fine": it isn't fine for them, and they need permission to feel it.
Use the last weeks well
Once the children know, the last weeks with the outgoing au pair become an asset. They are the time for a child to say goodbye properly, which is exactly what Leo and Mia never got.
A common mistake is to start pulling back: the outgoing au pair does less, parents take over "to get the kids used to it". In practice this front-loads the loss. The child experiences the goodbye twice, once when the relationship cools and again on departure day. Let the relationship stay warm until the end.
Rituals that give a child closure
Rituals matter more for children than for adults, because children understand endings through things they can see and hold.
- A photo book of ordinary days: not just holidays. Breakfast, the playground, the walk to school. Make it together and let the child keep it by their bed.
- A recorded bedtime story: ask the outgoing au pair to record herself reading a favourite book or singing the bedtime song. For a small child this can be a comfort for months.
- A goodbye letter or drawing: from the child to the au pair, and ideally one back. Older children often want to write theirs privately.
- A countdown for 5–9 year olds: a paper chain or a calendar with the last days marked. It makes the end visible instead of sudden.
- A proper goodbye moment: planned, unhurried and with the child present. Not a rushed hug on a school morning.
The adult side of this farewell, from the reference letter to the final pocket money, is its own project. The guide to saying goodbye to your au pair covers that half. What matters for the children is that their goodbye is scheduled on purpose, not squeezed in around the flight.
Key takeaway: A child who got a real goodbye has something to hold on to. A child who didn't tends to take the unfinished business out on whoever arrives next.
Keep the routine identical: the single biggest help for a child adjusting to a new au pair
If you do only one thing from this article, do this. The most effective way to help a child adjust to a new au pair is to keep everything around that au pair exactly the same. Same bedtime, same order, same song, same night light, same number of stories. The person changes; the shape of the day does not.
Routine is how young children know they are safe. When the person running bedtime changes and the bedtime itself changes too, the child loses two anchors at once. When only the person changes, the routine carries the child through the gap.
Capture the routine at the level a child notices
This is where most handover notes fall short. They record what the adults need ("bedtime 7:30, brush teeth, two stories") and skip the details the child is checking for. Leo wasn't upset that Hanna didn't know the bedtime. He was upset that she didn't know the lamp, the song and the door.
| Routine anchor | What to write down | Why a child cares |
|---|---|---|
| Wake-up | Who goes in first, what is said, lights or curtains | The first minute sets the tone of the day |
| Breakfast | Which cup, which seat, what's allowed on the toast | Small objects are big signals of "home" |
| After school | Snack first or play first, quiet time, questions or no questions | Tired children melt down when the order changes |
| Bath | Toys, water temperature, hair wash days | Bath is where a lot of trust gets tested |
| Bedtime | Order of steps, songs, lamp, door, comfort toy, what to say when they call out | The highest-stakes routine in the whole day |
Ask the outgoing au pair to walk through each routine out loud while you write. They know things you don't, because they have been doing it every night. The broader operating knowledge of the house, from school contacts to the boiler, belongs in the au pair to au pair transition handover. The children's routines deserve their own, more detailed pass.
Put it where the new au pair can use it on night one
A binder in a drawer doesn't help at 7:45pm when a four-year-old is crying. The routine has to be accessible in the moment, and it has to be the same for everyone who does bedtime.
This is exactly what the child profile in AuPairSync is built for: each child's routines, from wake-up to bedtime, are stored with their time, who is responsible and free-text notes for the details ("star lamp on before the big light goes off, door open a hand's width"), with separate weekday and weekend versions, and they show up in the family calendar. The new au pair can run the same bedtime, in the same order, from the first evening. If you haven't filled in your children's profiles yet, the guide to what every au pair needs to know about your kids walks through what belongs there, including favourite foods and comfort items.
- Write the routine before the outgoing au pair leaves, not after. Afterwards you are reconstructing it from a crying child.
- Have the new au pair shadow at least one full bedtime if there is any overlap.
- Without overlap, a parent does the first two or three bedtimes with the new au pair present, following the written routine exactly.
- Resist improving the routine during the changeover. Earlier bedtime, fewer stories, no more screens: all fine ideas, all for two months later.
Key takeaway: Change the person or change the routine, never both at once. Save every improvement you're tempted to make until the new au pair is settled.
What "normal" looks like in the first weeks
Even with good preparation, most children react. Knowing what is normal keeps parents from panicking and keeps the new au pair from concluding that the placement is failing in week two.
Reactions that are common and usually pass
- Regression: toilet accidents, waking at night, wanting a bottle or a dummy back, baby talk.
- Clinginess: following a parent from room to room, tears at drop-off, refusing to let a parent leave for work.
- Rejection of the new au pair: "I want Mummy to do it", refusing her help, testing her rules much harder than they ever tested the previous au pair's.
- Idealising the old au pair: "Lucía never made me wear a coat." She did. It doesn't matter.
- Delayed reactions: a child who seemed fine for two weeks and then falls apart. This is common in school-age children, who hold it together until they feel safe enough not to.
For most children these reactions ease over a few weeks as the new routine becomes familiar and the new au pair becomes a known person. Respond to them with patience rather than consequences. A four-year-old who wets the bed after a loss needs reassurance, not a sticker chart.
When to get more help
Some signs deserve a conversation with your paediatrician, the school or a child psychologist rather than more waiting:
- Sleep or eating problems that are still getting worse after about a month instead of slowly improving.
- Withdrawal from things the child used to love, such as friends, favourite activities or play.
- Distress that spreads into school, with teachers noticing changes in behaviour or concentration.
- Persistent fear or anxiety about other people leaving, including parents.
These are not signs that you handled the changeover badly. Some children are simply more sensitive to separations, and an au pair change can surface that for the first time.
Protect the new au pair from becoming the villain
The new au pair walks into a situation they didn't create: a grieving child, an idealised predecessor and a routine they don't know yet. Without help, they easily become the face of the loss. That is hard on them, and it slows the child's adjustment, because a child can't bond with someone they have cast as the enemy.
What to tell the new au pair before they arrive
- That the children loved the previous au pair, and that some rejection in the first weeks is expected and not personal.
- The exact routines, in writing, before the first bedtime.
- The children's comfort items and sore spots, such as the toy that must never be washed or the topic that brings tears.
- That you will back them up, in front of the children, from day one.
What parents can do in weeks one to three
- Take the hard edges yourself. For the first weeks, parents enforce the unpopular rules. Let the new au pair start with the fun parts: the playground, baking, the walk to the library.
- Never compare out loud. "Lucía always managed to get you dressed" turns the new au pair into a disappointing copy.
- Give the new au pair their own thing. A game from their home country, a new song, a special Saturday walk. Something that belongs to them and not to the predecessor.
- Stay nearby, then step back gradually. Be present for the first bedtimes, then in the next room, then out for the evening.
- Check in with the au pair, not just the children. A new au pair being rejected by a four-year-old needs to hear that it's going as expected.
The general mechanics of the arrival are covered in the first week with your au pair survival guide. For the children's side, fold a short question into your weekly check-in with the au pair: how did bedtime go, what worked, what did the kids push back on. Small corrections in week two prevent a stand-off in week six.
Key takeaway: The new au pair doesn't need to replace the old one in the children's hearts. They need the space to become someone the children know on their own terms.
Staying in touch without reopening the wound every week
Children often ask whether they can still talk to the au pair who left. Usually they can, and contact can be a real comfort. But the timing and frequency matter.
- A short message or video from the outgoing au pair shortly after she gets home reassures a child that she arrived safely and still exists.
- Avoid daily video calls in the first weeks. They can keep the child in a state of waiting, and they make it harder to accept the new au pair.
- Settle into something occasional and predictable: a call once a month, a postcard, a message on birthdays.
- Let the child lead. Some children want lots of contact at first and then drift. That drift is a sign of healthy adjustment, not of forgetting.
Keep the photo book and the recorded story within reach. For younger children these are often more comforting than a live call, because they don't end.
Your changeover checklist for the children
- As soon as the date is fixed: decide when to tell each child, by age.
- 4–6 weeks before: tell school-age children. Start the photo book together.
- 2–3 weeks before: tell younger children. Record the bedtime story. Start the countdown.
- 2 weeks before: write down every routine in child-level detail with the outgoing au pair.
- 1 week before: share routines, comfort items and sore spots with the new au pair.
- Last days: a planned, unhurried goodbye with the children present. Letters and drawings exchanged.
- Weeks 1–3 with the new au pair: identical routines, parents hold the unpopular rules, no comparisons, first bedtimes with a parent nearby.
- After about a month: check how each child is doing, and ask for help if things are getting worse rather than better.
Why the children's side deserves its own plan
Host families put real work into au pair changeovers: the matching, the visa, the handover document, the room. That work matters. But at the centre of the whole arrangement are children who, every year or two, lose someone they loved and are asked to start again with a stranger.
Children can do that, and most do it remarkably well, as long as the adults around them make the loss visible, the goodbye real and the routine unbroken. Claire's second changeover, a year later, started with a conversation at the dinner table six weeks out and an afternoon writing down the star lamp, the song and the door. Leo cried when Hanna left. Then he showed the new au pair exactly how bedtime works.
