Talking to children is its own register — and in French, that register is more codified than in English. Adults addressing children deploy a recognizable bundle of features: universal tutoiement, an elaborate set of pet names, command forms used affectionately, a special use of the imparfait that has nothing to do with past time, and a toddler-vocabulary core (dodo, doudou, pipi, bisou) that monolingual French children learn before they learn most regular words. Recognizing these features is essential if you'll be around French families, watch French children's media, read French children's literature, or simply want to understand why a French parent at the next table sounds like they're speaking a different dialect. This page maps the system.
Tutoyer always — children are never vous
The first rule is absolute. French adults say tu to children — every child, every age, including children they have just met for the first time. Using vous with a child sounds aggressively cold or theatrically formal, the kind of joke a parent might make to a misbehaving five-year-old precisely because it's so out of register.
Bonjour, comment tu t'appelles ?
Hello, what's your name?
Tu as quel âge, toi ?
How old are you?
Tu veux un bonbon ?
Do you want a candy?
The reverse direction — children to adults they don't know — generally requires vous until the adult invites tu. Children to family members, family friends, teachers in primary school: tu. To a stranger on the street: vous (children are taught this by age four or five).
Pet names — the hypocoristic vocabulary
French has a deeply elaborated set of affectionate names for children. They are not interchangeable with English equivalents — each one carries its own connotations, and using them well is part of speaking French to children fluently.
Allez, mon chéri, on va se laver les mains.
Come on, sweetie, let's wash our hands.
Tu as bien dormi, ma puce ?
Did you sleep well, sweetie?
Viens ici, mon trésor.
Come here, my treasure.
N'aie pas peur, mon poussin.
Don't be afraid, little one.
C'est l'heure du dodo, mon coco.
It's bedtime, sweetie.
The core set:
- mon chéri / ma chérie — "my dear / my darling"; the all-purpose default. Works with children, partners, very close friends.
- ma puce — literally "my flea"; bizarrely affectionate. Almost exclusively used with girls and small children; the gender of the recipient does not have to be feminine.
- mon trésor — "my treasure"; warm and slightly more emphatic than chéri. Common with very young children.
- mon poussin — "my little chick"; warm, slightly playful.
- mon coco / ma cocotte — "chick"; informal, friendly. Mon coco is also used between adults as a slightly mocking/affectionate term ("my friend, you...").
- mon ange — "my angel"; somewhat more performative.
- mon lapin — "my rabbit"; affectionate, common.
- mon chou — "my cabbage"; this one really does mean cabbage. (informal), very common.
- mon biquet / ma biquette — "my little goat"; rural-flavored, affectionate.
The grammatical gender of the pet name does not have to match the child's sex. A boy can be called ma puce — though mon forms are more common with boys and ma forms with girls in practice. (informal) across the board.
Imperatives — the language of caretaking
Caretaker speech is dense with commands, and French children hear the tu-imperative constantly.
Lave-toi les mains avant de manger.
Wash your hands before eating.
Mange tes légumes, s'il te plaît.
Eat your vegetables, please.
Ne touche pas, c'est dangereux.
Don't touch — it's dangerous.
Viens là, donne-moi la main.
Come here, give me your hand.
Range tes jouets avant de te coucher.
Put your toys away before bed.
Note the structures:
- Affirmative tu-imperative drops the final -s of -er verbs: tu manges → mange ! (never manges ! in this position).
- Pronominal verbs use the imperative pattern verbe-toi: lave-toi, dépêche-toi, assieds-toi.
- Negative imperative places ne and pas around the verb, and pronouns return to their normal preverbal position: Ne touche pas (not touche-pas); Ne te lève pas (not lève-toi pas).
Dépêche-toi, on va être en retard !
Hurry up, we're going to be late!
Ne te mets pas si près de la télé.
Don't sit so close to the TV.
The s'il te plaît / merci training begins early — French parents drill these from age two with the formula On dit ? ("What do we say?") to which the child is expected to supply S'il te plaît ! or Merci !
Imparfait hypocoristique — past tense as affection
This is the feature that most surprises learners. French adults often use the imparfait to address a child who is right there, doing the thing being described, now. The past tense is not literal — it's a softening device, a way to lavish affection on the present moment by displacing it slightly.
Oh, comme il était mignon, ce petit !
Oh, how cute he was, this little one! (said while looking at the child now)
Qu'est-ce qu'il voulait, mon chéri ?
What did my sweetie want? (asking what the child wants right now)
Tu étais bien sage aujourd'hui, hein ?
You were very good today, weren't you? (affectionate, even when the day isn't over)
Comme tu étais belle dans cette robe !
How pretty you were in that dress! (often said while child still wears it)
The imparfait hypocoristique (also called imparfait d'affection) creates emotional distance — the present moment is framed as something you can already look back on tenderly. It is a marked register: warm, doting, cooing. Adults also use it with babies, pets, and occasionally with romantic partners in playful contexts. (informal, register: doting/affectionate).
Pretend-play imparfait — On disait que...
A second specialized imparfait appears in children's pretend play, where it sets up the imaginary scenario.
On disait que tu étais le pirate et moi, j'étais le capitaine.
Let's pretend you were the pirate and I was the captain.
On disait que c'était la nuit et qu'il y avait un dragon.
Let's say it was night and there was a dragon.
Et toi, tu étais la princesse, d'accord ?
And you were the princess, OK?
The construction On disait que + imparfait is the standard French way to propose a pretend scenario. Children produce it spontaneously by age four or five. Adults use it with children to enter their imaginative world. It has nothing to do with reporting past speech — on disait here is a fixed pretend-play formula, like English "Let's say" or "Let's pretend."
Storytelling — Il était une fois
Stories begin with Il était une fois — the French equivalent of "Once upon a time," and a fixed imparfait formula.
Il était une fois une petite fille qui s'appelait Cendrillon.
Once upon a time there was a little girl named Cinderella.
Il était une fois, dans un pays lointain, un roi très puissant.
Once upon a time, in a faraway land, there was a very powerful king.
The imparfait dominates fairy-tale narration in French — habitual states, ongoing scenes, character descriptions. The passé simple often appears for the punctual events that move the plot, but the descriptive backbone is imparfait. Children encounter this rhythm before they have any grammatical vocabulary for it.
Toddler vocabulary — the words children learn first
Every language has a baby register; French has a particularly stable one.
C'est l'heure du dodo.
It's bedtime.
Tu as fait pipi ?
Did you go pee?
Donne-moi un bisou !
Give me a kiss!
Où est ton doudou ?
Where's your stuffed animal / cuddle toy?
On va voir mémé et papy ce week-end.
We're going to see grandma and grandpa this weekend.
The core lexicon:
- dodo — sleep, bed. Faire dodo = go to sleep. (child register, very common)
- doudou — a child's cuddle toy or comfort blanket. Universal in French households.
- pipi — pee. Faire pipi = go pee. Used freely with children.
- caca — poo. Same construction; same register.
- bisou — kiss. Faire un bisou, faire des bisous. Used by all ages, not only with children.
- mémé / papy — grandma / grandpa. (informal), household register. Mamie is the more common feminine variant; mémé is regional or older. Formal alternatives: grand-mère / grand-père.
- maman / papa — mom / dad.
- tata / tonton — auntie / uncle. Reduplicated child versions of tante / oncle.
- nounou — nanny, daycare provider. From nourrice.
- lolo — milk (very young children only). Less universal than the others.
- toutou — doggy. Le toutou for a dog, child register.
- miam-miam — yum-yum. Used freely with children at mealtimes.
These words are not "baby talk" in a pejorative sense — adults use them when speaking to or about children well into school age, and many (dodo, doudou, bisou) are used in light adult speech too.
Reduplications and softeners
Beyond tata / tonton, French uses two related softening devices in caretaker speech. The first is reduplication of a child's first name (Léa → Léa-Léa, Lou → Lou-Lou) — affectionate, common with toddlers, fading as the child grows. The second is the productive -ot / -otte diminutive (Pierre → Pierrot; frère → frérot, little brother), and the affectionate feminine -ette (fille → fillette; jeune → jeunette). Reduplication and -ot suffixation are different mechanisms; both are common, but they're not the same operation.
Mon petit frérot, viens ici !
My little bro, come here!
C'est ma fillette à moi, ça.
That's my little girl.
Common Mistakes
❌ Bonjour, comment vous appelez-vous ? (to a five-year-old)
Incorrect register — children are addressed with tu, never vous.
✅ Bonjour, comment tu t'appelles ?
Hello, what's your name?
❌ Touche pas ! (to a small child, written without ne)
Acceptable in casual speech but in writing or careful caretaker speech use ne... pas.
✅ Ne touche pas, c'est chaud !
Don't touch, it's hot!
❌ Lave tes mains. (forgetting the reflexive)
Incorrect — laver les mains is reflexive: se laver les mains.
✅ Lave-toi les mains.
Wash your hands.
❌ Mon chérie. (gender-mismatch with the possessive)
Incorrect — mon goes with masculine forms; ma chérie is the feminine.
✅ Ma chérie. / Mon chéri.
My darling (f.) / My darling (m.)
❌ Tu es beau aujourd'hui. (interpreting imparfait hypocoristique as a true past)
When a French speaker says 'Tu étais sage aujourd'hui' to a child still in the room, don't read it as past — it's affectionate marking.
✅ Tu étais bien sage tout à l'heure, mon chéri.
You were very good earlier, sweetie. (affectionate imparfait)
Key Takeaways
Caretaker French is a coherent register: universal tutoiement; a layered set of pet names (mon chéri, ma puce, mon trésor, mon poussin, mon coco); imperatives that drop the -s on -er verbs (mange, lave-toi); the imparfait hypocoristique as an affective softener divorced from past time; the pretend-play On disait que + imparfait; the fairy-tale Il était une fois; and a small but stable toddler vocabulary (dodo, doudou, pipi, caca, bisou, mémé, papy). Learners who study only the standard register can find a French family conversation suddenly opaque — half of it is in caretaker code. Recognize the code, and the conversation opens up.
