Baby scribbling: at what age?
Most children scribble around 18 months. The U.S. Centers for Disease Control and Prevention (CDC) list “scribbles” among the motor milestones for this age. Their checklist, revised in 2022, includes only skills achieved by at least 75% of children. Some babies leave their first marks earlier, as soon as they can hold an object and rub it on a surface. The circle comes much later, around age 3.
Here are the main stages of scribbling, what it actually develops, the right materials for each age, and how to support a toddler without directing them.
The stages of scribbling, from the first line to the circle
The ages below are average milestones. Differences of several months from one child to another are common, and opportunities to practice matter a great deal.
Around 12 to 18 months: discovering marks by chance
The toddler holds the crayon in their fist, like a stick. They hit the page, rub it, or put the crayon in their mouth. One day, a mark appears. They then discover a cause-and-effect link: my movement leaves a mark. This discovery often interests them more than the mark itself.
Ages 18 to 24 months: large back-and-forth scribbles
The baby now scribbles intentionally. The lines go in all directions, back and forth or in loops. The movement comes mainly from the shoulder and the entire arm, while the wrist remains relatively still. The marks often extend beyond the page, which is normal at this age.
In the 1960s, American researcher Rhoda Kellogg catalogued about twenty basic scribbles in young children's drawings. Dots, lines, zigzags, loops, and spirals appear from one child to another, regardless of culture.
Ages 2 to 3: more controlled lines
The elbow and then the wrist become more involved. The child sometimes slows down to watch the line as they draw it. They begin to imitate a gesture demonstrated by an adult, such as a vertical line. They stop more often on the page and deliberately vary the colors.
Around age 3: the circle and first names
According to the CDC milestones, a 3-year-old draws a circle when shown how. This is also the age when many children start naming their drawings, often after finishing them. The scribble then becomes a representation: “that's dad,” “that's the rain.”
Why Scribbling Matters for Development
Scribbling is not a preparatory stage for writing that needs to be hurried along. It is a complete activity in its own right, engaging several aspects of development.
- Motor skills. Control of movement progresses from the shoulder to the fingers. Scribbling exercises this progression precisely, just like stacking blocks or threading beads.
- Hand-eye coordination. The child learns to watch what their hand is doing, then adjust their movement based on what they see.
- Understanding cause and effect. Pressing harder produces a darker line. Changing crayons changes the color.
- Symbolic thinking. When a line “becomes” a cat, the child uses one form to represent something else. It is the same ability used in pretend play.
We explain these two aspects of the movement in our article about fine and gross motor skills. The transition to representation is explored in our article about symbolic play between 18 and 36 months.
How does a baby hold a crayon?
The first grip is a fist grip: the crayon extends from the bottom of the hand, pointing toward the paper. It is the logical continuation of the palmar grasp, which we describe in our article about when babies start grasping objects.
Over time, the fingers take over from the palm. The so-called “tripod” grip, between the thumb, index finger, and middle finger, develops during the preschool years. A study published in 1990 in the American Journal of Occupational Therapy observed pencil grips in children aged 3 to 6. It describes steady progress toward these mature grips over this period.
Practical takeaway: there is no need to correct the grip of a 2-year-old. A fist grip suits their strength and control. Thick crayons naturally make it easier to move toward a finer grip.
What materials are suitable for a baby's first scribbles?
The right materials are simple, sturdy, and suitable for a toddler's mouth, because they will inevitably end up there.
- Large wax crayons or thick chalk. They withstand pressure and fit well in a fist.
- Washable broad-tip markers, preferably from age 2 onward, with caps stored out of reach.
- Finger paint, for those who prefer the sensation to the tool.
- Large sheets of paper, secured to the floor or table with adhesive tape so they don't slip.
Read the packaging. A product carrying the warning “not suitable for children under 36 months” may contain small detachable parts. Choose a CE-marked material intended for your child's age. Stay beside them during the session: a toddler still explores with their mouth, as we explain in our article why babies put everything in their mouths.
Sitting, lying down, or standing?
All three positions have their benefits. On their stomach on the floor, the child supports themselves on their forearms and stabilizes their shoulders. Sitting at a small table, with their feet on the floor, they gain precision. A sheet fixed to the wall or an easel engages the shoulder and wrist differently. Alternating is more useful than choosing one.
How can you encourage your baby to scribble without directing them?
The adult's main role is to set things up and show interest, much less to demonstrate. A few principles can help.
- Describe rather than judge. “You made big red circles” supports language and attention. “That's beautiful” often brings the conversation to an end.
- Don't ask “What is it?” Before age 3, scribbles generally don't represent anything. The question may put the child in a difficult position.
- Show only one gesture if they ask. A toddler learns a lot by watching an adult draw beside them, without instructions. Our article on learning through imitation explains this mechanism.
- Keep it short. Two or three minutes of attention at 18 months is a real session.
- Keep the materials accessible. A box of crayons and a few sheets of paper kept in the same place always encourage your child to come back to them.
A toddler doesn't need coloring books or models to copy. A blank sheet of paper and three crayons leave more room for exploration, a principle we develop in our article on free play and creativity.
Baby still isn't scribbling at 18 months: should you be concerned?
Failing to reach a single milestone is not enough to draw a conclusion. Many children have simply never held a crayon. Offer suitable materials for a few weeks, and observe.
The CDC nevertheless recommends discussing it with a doctor when a child does not reach several milestones for their age, or loses a skill they had acquired. The follow-up appointments scheduled in the health record are the right time to raise the question. The doctor looks at overall development, not an isolated action. If your child already grasps, handles, and stacks objects, our article on the age when babies stack cubes provides other useful fine motor skill milestones.
They scribble on the walls: how should you respond?
It is almost inevitable, and it is not provocation. A large blank wall is very tempting for a child discovering the marks they can make. The most effective response is practical: put the crayons out of reach between drawing sessions, and offer a large permitted surface.
A roll of kraft paper attached to the wall, a chalkboard, or the back of a poster will do the trick. Simply say, « we draw on the paper », and redirect the child without scolding. Washable crayons and markers help limit the mess while the rule becomes established.
In summary
- In most cases, babies scribble around 18 months; a circle comes around age 3, with a demonstration.
- The movement progresses from the shoulder to the fingers: a fist grip is normal before age 3.
- Chunky crayons, large sheets secured in place, and close supervision are enough.
- Describe what the child is doing, without judging or asking what the drawing represents.
- A single missed milestone is not concerning; several missed milestones warrant discussing with a doctor.
