A babysitter for a baby can help from the first few weeks, provided the person is reliable, the evening is prepared, and the parents remain reachable. There is no legal minimum age in France for leaving a child with an occasional caregiver. In practice, the easiest period is before 7 or 8 months, before separation anxiety, and then again after around 18 months. In between, it is possible too, but leaving requires more preparation. This guide explains how to choose the person, what to leave in writing, and how to handle crying when you leave.
At what age can you leave your baby with a babysitter?
There is no medical answer to this question. A three-week-old infant can be cared for by a competent person for two hours while their parents go out to dinner. What matters is the gap between what the baby needs and what the person knows how to do. Three periods stand out.
Before 7 months: the easiest period emotionally
Baby does not yet make a clear distinction between the adults who care for them. They will accept a bottle, a diaper change, and soothing from an unfamiliar person without protesting, as long as their needs are met. The difficulty lies elsewhere: the person must know how to prepare a bottle, hold an infant, recognize a fever, and put a baby to sleep on their back. A teenage babysitter with no experience with infants is not the right choice at this age, even for two hours.
Between 7 and 18 months: separation anxiety makes leaving more difficult
At around 7 to 9 months, baby understands that their parents still exist even when they are out of sight, and protests when they leave. This is a normal stage, described in our article on separation anxiety and the age when it appears. It does not rule out using a babysitter, but it changes the approach. Baby should have seen the person at least once beforehand, in the parents' presence, and the departure should be announced clearly rather than concealed.
After 18 months: the child understands that you come back
The child has understood that their parents come back. They may cry when you leave, but will calm down quickly if the person offers them something interesting. They accept a new person more easily, especially if that person plays with them before the parents leave. This is also the age when you can explain the evening in simple words: “Tonight Léa will put you to bed; we'll come back while you're sleeping.”
How do you choose a babysitter for a baby?
The usual channels are friends and family, specialized platforms, local ads, and word of mouth among parents at daycare. Whatever the channel, four checks are essential before leaving an infant.
- Real experience with babies under one year old, not just with school-age children. Ask about specific situations: a refused bottle, a baby crying for no apparent reason, or heavy spit-up.
- Basic safety practices: putting baby to sleep on their back, in an empty crib, as recommended in infant sleep guidelines. Checking a bottle's temperature. Never leaving a baby alone on a changing table or in a bath.
- An initial meeting at home, in your presence, lasting at least one hour. Observe how the person speaks to baby and how baby responds. Show them the rooms and equipment.
- Availability and punctuality, tested during a first short evening of no more than two hours, before considering a longer outing.
From an administrative standpoint, paid occasional childcare at home must be declared. The chèque emploi service universel is the system intended for this purpose. It provides insurance coverage in the event of an accident and gives both parties a clear framework.
What should you leave in writing for the babysitter?
A sheet on the refrigerator or a message on their phone, with the information in this order.
- Both of your phone numbers, the name and address of the place where you will be, and the number of someone close who can be reached if you do not answer.
- 15 for a medical emergency, 112 from a mobile phone, and the exact home address, which the person may not know by heart.
- The usual evening routine: the time of the last bottle or breastfeeding if you have expressed milk, the amount, bedtime, and the precise bedtime ritual.
- What baby accepts and refuses: their preferred sleeping position, their comfort object, whether the night-light should be on, and the sound that soothes them.
- Health instructions: known allergies, any current treatment with the dose and time, and what to do in case of a fever.
- What is prohibited: giving anything other than what has been planned, leaving the apartment, opening the door to anyone, or filming or photographing baby.
How can you prepare the evening so everything goes well?
The essentials happen before the babysitter arrives. A baby who has eaten, had a bath, and is wearing pajamas gives the person a simple evening: one last bottle, a routine, and bedtime. Our article on bathing baby in the evening or morning helps you schedule this moment so it remains a familiar cue rather than a chore delegated to someone else.
The bedtime routine should be written down and demonstrated, not just described. If you always sing the same song, specify which one. If baby falls asleep with the door ajar, say so. These details are what help a child accept being put to bed by someone else. Our article on routines and emotional security explains why consistency in the routine matters more than the person carrying it out.
Prepare the equipment
Set out everything the person will need: prepared bottles or expressed milk in the refrigerator, diapers, wipes, spare pajamas, a thermometer, and baby's comfort object. Check that the baby monitor is switched on and that the person knows how to use it. If you do not have one, our guide to choosing a baby monitor explains what really matters for an evening at home. Quickly check the risk areas, as described in our guide to making your home safe for baby: stairs, outlets, household products, and windows.
Plan a play area if baby is still awake
If you leave before bedtime, the person must be able to place baby safely on the floor while preparing the bottle. A play mat on the floor, a few objects to handle, and a clear space are enough. A crib is not a playpen, and the sofa is not a play area.
What should you do if baby cries when you leave?
Leave anyway, calmly. Sneaking away while baby is looking elsewhere may prevent immediate tears, but teaches the child that their parents can disappear without warning. A goodbye announced with the same gesture every time leads to brief crying and lasting trust. Say goodbye, say that you will come back, and leave without turning back. The crying usually stops within a few minutes. Ask the babysitter to send you a message ten minutes after you leave, not before.
If the crying continues for a long time every time someone babysits, two causes are common: the person has not been seen often enough beforehand, or the evening starts when baby is already tired. Having the babysitter arrive an hour earlier so they can play with baby before bedtime often solves the problem. Our article on organizing naps and daily routines helps identify the time when baby is most receptive.
Babysitter, grandparents, or shared childcare: what are the differences?
Grandparents know baby and do not need the instruction sheet, but they may have habits that differ from yours regarding sleep or feeding. Our article on baby equipment at the grandparents' house discusses what to leave for them and what is best to clarify beforehand. A babysitter follows your instructions to the letter, but baby does not know them. Shared childcare between two neighboring families, with each taking turns caring for the other's children, combines proximity and no cost, but requires regular organization. The right choice depends on frequency: for a monthly outing, a babysitter is enough; for a weekly outing, a more stable arrangement is preferable.
Why going out without baby is beneficial for parents
Many parents postpone their first evening out because of guilt. A three-hour outing does not harm a well-prepared baby, and often leaves parents more available the next day. The first weeks after a birth can put a couple under considerable strain, as explained in our article on what really changes in a relationship after having a baby. Regular time together, even if brief, is part of what helps couples stay strong over time.
Key takeaways
- There is no minimum age: a babysitter can care for a baby from the first few weeks if they have experience with infants.
- Before 7 months, the difficulty is technical; between 7 and 18 months, it is emotional; afterward, it is mainly organizational.
- An initial meeting in your presence, a first short evening, and a written instruction sheet are the three conditions for relaxed childcare.
- Bath, meal, and pajamas should be done before you leave; the bedtime routine should be demonstrated, not merely described.
- Say goodbye, leave, and do not turn back. Departure tears are brief when the framework is consistent.
