A four-year-old lives half the day in make-believe: monsters under the bed, an invisible friend, stories that never happened. At the same time, friends matter more than ever, and rules become fascinating, especially when someone else breaks them. This is the year your child can hold a long conversation, ride a bike without stabilisers and lie to your face without blinking.
Sunday morning in a row of terraced houses in Bromma. A four-year-old explains to her little sister that you are not allowed to walk on the floor, because the floor is lava. Ten minutes later the same child is in tears, because little sister is not following the rules. Imagination and rules, in the same game, taken equally seriously. That is the four-year-old, and it is one of the most fun years to be a parent, if you have the energy.
What can a four-year-old do?
| Area | Typical at four |
|---|---|
| Gross motor skills | Hops on one leg, climbs the climbing frame, throws and catches a large ball, and many learn to ride a bike without stabilisers during the year |
| Fine motor skills | Cuts along a line with scissors, draws a person with a head, legs and arms, does up buttons, holds a pencil more or less like an adult |
| Language | Long sentences, retells an event in the right order, is understood by strangers, makes up words and rhymes, asks what words mean |
| Social | Has best friends, plays in a group with roles, negotiates rules, can be left out and feel it |
| Thinking | Sometimes separates fantasy from reality, but not always. Counts to ten, recognises a few letters, understands yesterday and tomorrow |
| Independence | Gets dressed alone apart from the fiddly bits, uses the toilet alone, washes hands, lays the table |
Imagination: monsters, invisible friends and stories that are true
A four-year-old's imagination is at its peak, and the ability to tell it apart from reality lags behind. That means the monster under the bed is real at eight o'clock at night, that a story about a dragon in the bushes at förskola (municipal preschool, from age one) can be completely true for your child, and that an invisible friend can have a name, a favourite colour and firm opinions about dinner.
All of this is healthy. Imagination is the four-year-old's workshop for feelings. In play you die and wake up again, you get angry without anyone being hurt, you are the one in charge. Play along, but keep one foot in reality: yes, that sounds like a scary monster, and there are no monsters in this room, I know because I have checked. The bedtime fears that appear around now are covered in our guide to Children who are afraid of the dark.
Friends and the first real experience of being left out
By four, most children have one or two friends they would rather play with than anyone else. Play becomes a group activity with roles and rules, and with it comes the first real experience of exclusion: you can't play with us. It is said every day at every förskola, and it hurts a four-year-old, who cannot yet shrug it off.
What you can do at home is listen without immediately trying to fix it. Your child needs to tell the story more than they need advice. Invite one friend over at a time: two children play, three children often turn into two against one. And ask the förskola how things look during the day. They see more than you do, and a child who is often left out needs adults who help them into the game.
Rules: the four-year-old as police officer
A four-year-old loves rules, at least when they apply to other people. They report siblings who have not washed their hands, point out that Dad drove through a red light, and take the rules of a board game deadly seriously. Losing a game can end in tears and flying pieces. That is not bad manners, it is a child who has just understood that rules exist and has not yet understood that they also apply to themselves.
- Games: choose games decided by luck rather than skill, and play short rounds. Let your child lose sometimes, it is practice
- Rules at home: few and clear. Your four-year-old will test them and then defend them against younger siblings
- Fairness: your child counts the strawberries. Share equally when you can, and otherwise say why you can't
- Consistency: a rule that applies on Monday but not on Friday makes a four-year-old frustrated and more likely to test it
Lying at four: not really lying
At some point during the year it arrives: I didn't eat the sweets, with chocolate all round the mouth. A four-year-old's lies are rarely planned. The child wishes it hadn't happened, and so it didn't. They may also blame the invisible friend, the cat or a sibling. It is the beginning of understanding that other people do not know what the child knows, and that is actually a leap forward in thinking.
Make it easy to tell the truth. Don't ask did you eat the sweets when you already know the answer; say instead: I can see the sweets are gone, tell me what happened. No trap, no big reaction. There is more on what lies mean at different ages in Children who lie.
Sleep, food and the body
A four-year-old needs 10 to 13 hours of sleep, almost all of it at night. The daytime nap is gone for most, and a child who falls asleep in the car at five o'clock is heading for a late and difficult evening. Many four-year-olds have more nightmares than before, and some get night terrors. A fixed bedtime routine and a screen-free hour before bed are what help most.
The body grows more slowly than in the first years, and appetite follows. A four-year-old can eat a lot one day and almost nothing the next. It evens out over the week. The four-year check-up at BVC (the child health clinic every family is enrolled in) covers height, weight, sight and hearing, and it is a good moment to raise anything on your mind about food, sleep or language. Four is also the earliest age to swap the rear-facing car seat, and preferably later than that.
When to talk to BVC or the förskola
- People outside the family find your child hard to understand, or the stammering is heavy and goes on for a long time
- Your child rarely plays with others and does not seem to notice when other children invite them in
- Your child has several long meltdowns a day that are hard to end, both at home and at förskola
- Your child does not seem to see or hear well: sits close to the TV, often says what?, squints
- Your child is afraid of things in a way that limits everyday life for several weeks
- The förskola raises a concern. Listen, even if it does not match how your child is at home
How we do it with our families
Denise looks after a four-year-old in Solna two afternoons a week, and the child has an invisible friend called Bobo. Bobo eats a snack, Bobo has his own chair, and when something breaks, Bobo did it. Denise plays along without building it up: she says hello to Bobo, but when the toy car breaks she says that she and the child will fix it together, because Bobo is only a child after all. She speaks Spanish with the child while they play and Swedish at the table, as the parents have asked, and her note at the end of the day says which game they played, who from förskola the child talked about, and whether Bobo was there.

Frequently asked questions
Is it normal for a four-year-old to have an invisible friend?
Yes, very common and completely harmless. The invisible friend is a way of practising relationships, trying out roles and occasionally shifting the blame onto someone else. Play along without overdoing it, and don't worry. Most of them disappear on their own before school starts.
Why does my four-year-old lie?
Because the line between fantasy and reality is still blurry, and because your child wants to avoid a reaction they don't like. It is not lying in the adult sense. Calmly ask what happened, without an interrogation, and make it easy to tell the truth.
How much sleep does a four-year-old need?
Roughly 10 to 13 hours a night. Most four-year-olds no longer nap during the day, so almost all of it has to happen at night. A four-year-old who wakes at half past six then needs to be asleep by half past seven at the latest, and the bedtime routine needs to start half an hour before that.
Should a four-year-old be able to write their name?
No, it is not a requirement. Many four-year-olds recognise the first letter of their name and some write the whole thing in capitals, often mirrored. Interest leads the way. What matters before school is that your child likes books, can hold a pencil and dares to try.
