Your 3-Year-Old: Language, Emotions and First Steps Towards School

“Why is the sky blue? Why are you leaving? Why do I have to tidy up?” A 3-year-old talks a lot, argues, negotiates, and starts to really play with others. It is also the age when the question of school enters family conversations, sometimes long before your child is concerned.

Here are the paediatric milestones at 3, what you can expect from their language and emotions, where potty training stands, and what really prepares them for life in a classroom.

What can a 3-year-old do?

Most 3-year-olds climb stairs alternating feet, pull on loose trousers by themselves and are understood by others most of the time. The table brings together the milestones of the American CDC, reached by at least 75% of children of that age, those of the Canadian Paediatric Society (CPS) and those of the French screening booklet at 36 months.

These lists are there to spot a gap, not to rank children. The CPS advises talking to the doctor if your child seems behind in more than one area, and reminds us that a child born early is assessed by their corrected age.

How does a 3-year-old talk?

At 3, a child holds a conversation: the CDC expects at least two back-and-forth exchanges, questions starting with “who, what, where, why”, and speech that others understand most of the time. The speech therapy centre in Neuchâtel, Switzerland, describes a child at this age who expresses themselves in sentences and takes part in family conversations.

To help, the CDC suggests speaking to them in sentences a little longer than theirs. If they say “cat gone”, reply: “yes, the cat has gone into the garden”. Read together, asking what is happening in the picture, then what will happen next.

At home, they may hear Darija, Amazigh, Arabic or French: our notes on the multilingual child explain how to support these languages. The main stages since birth are in our article on language from 0 to 3.

Tantrums and emotions: what changes at 3

Tantrums do not disappear at 3, but your child has new tools to get through them: words. The CDC advises talking about their emotions with them and giving them the vocabulary to say what they feel (“you’re disappointed, you wanted to stay at the park”). It also suggests teaching them ways to calm down: breathing deeply, hugging a soft toy, retreating to a quiet corner.

The CPS notes that at this age children readily resist changes of routine. A rushed departure, a meal at a different time, an unplanned visit to relatives can be enough to set off the storm. The CDC advises setting a few simple, clear rules, such as “we play with gentle hands”, showing what to do instead when the rule is broken, and praising them when it is kept.

The right reactions during and after a tantrum are detailed in our article on young children’s tantrums. If a little brother or sister has just arrived, also read our advice on sibling jealousy.

Potty training at 3: where are they?

Many children are in the middle of learning, others not yet. The CPS places interest in the potty between 2 and 4 for most children, and advises seeing a doctor if they are still not using the toilet at 4. Accidents are part of learning, especially in times of change, such as the birth of a baby or a house move.

The gentle method and the equipment are in our guide to potty training. One point deserves attention: a child who holds back from having a bowel movement can become constipated, which makes stools painful and slows learning, the CPS warns. Our article on constipation gives the useful steps.

Are they ready for school?

In Morocco, official preschool covers children aged 4 and 5. At 3, depending on the family, a child is still at home, in a crèche or nursery, or already in the first section of a private school. To compare the options, see our guide to nursery school in Morocco.

Being “ready” at this age is mostly about independence and enjoying being with others. Naître et grandir points out that in nursery school children learn to wait their turn, follow rules, tidy their things, hang up their clothes and wash their hands before snack time, and that until age 6, play remains the most important activity for development. At home, this means:

1. dressing alone in easy clothes: elastic-waist trousers, shoes with Velcro;
2. eating alone with a fork and drinking from a cup;
3. tidying their toys into boxes at their height;
4. washing their hands alone, on a stable step stool at the sink;
5. getting used to separation: the CDC expects a 3-year-old to calm down within ten minutes of your leaving, for example when dropping them at nursery.

The CDC also advises preparing them for new places and people with stories or pretend games: playing “teacher”, telling the story of a child’s day at school. For the list of things to pack and the first days, see our article on starting crèche or nursery school.

Which games and toys at 3?

At 3, they like games with simple rules, modelling dough and stories. The CDC suggests:

• counting games: the steps on the stairs, fingers, olives on the plate;
• matching and opposites games: finding two identical pictures, saying big or small, fast or slow;
• an activity box with paper, pencils and colouring books;
• modelling dough to squash, pinch and roll into balls, which builds hand strength for writing and buttons;
• cooking: washing vegetables or mixing the dough with you;
• instructions in two or three steps: “go and get your shoes and your coat”.

It is also the age of first board games, the ones that teach waiting your turn, a skill the French screening booklet looks at in 36-month-olds. Our guide to board games by age helps you choose. Our creative games and puzzles sections complete the selection.

Sleep, screens, activity: the WHO guidelines at 3

The WHO recommends, between 3 and 4 years:

• at least 180 minutes of physical activity a day, including 60 minutes of energetic activity (running, jumping, climbing);
• no more than one hour of screen time a day, and less is better;
• 10 to 13 hours of sleep, naps included if they take one, at regular times.

The CDC adds: no screens in their bedroom. The park, the beach, the school yard: our outdoor activities by age give ideas for reaching those three hours effortlessly.

When should you see a doctor?

Talk to the paediatrician or the health centre doctor as soon as a doubt sets in, without waiting for the next visit. The CDC puts it simply: you know your child better than anyone.
