Left or Right? When Kids Pick a Dominant Hand, and How to Help a Left-Handed Child Color

Short answer: A hand preference usually starts to appear between ages 2 and 4, and a clear preference is usually established between 4 and 6, according to an NHS children's occupational therapy service in England. The American Academy of Pediatrics says some toddlers show a clear tendency by 24 months while many do not for several years. Both advise against choosing a hand for your child.

This page is general information, not medical advice. If you have a concern about your child's hands or movement, your child's doctor is the right person to ask.

When do kids pick a dominant hand?

Gradually, over the toddler and preschool years. Two sources we read give ages.

The American Academy of Pediatrics (AAP) says that by 24 months a toddler may show a clear tendency toward right- or left-handedness. It adds that many children do not show this preference for several years, and that some are ambidextrous, meaning they use both hands equally well (AAP, 2-year-olds).

A children's occupational therapy service in England's NHS gives a similar picture. A hand preference usually starts to develop between the ages of 2 and 4, and between 4 and 6 a clear hand preference is usually established (North Cheshire and Mersey NHS Foundation Trust).

Before starting school Most children prefer one hand for drawing, though some have started school when this happens Raising Children Network

The last row comes from the Raising Children Network, an Australian parenting website whose member organizations include the Murdoch Children's Research Institute (Raising Children Network).

The same NHS sheet explains what "preference" means. It is the consistent favoring of one hand for the skilled part of a task. When drawing, the preferred hand holds the crayon while the other hand steadies the paper. Both hands have a job.

The CDC milestone checklists we read, for ages 2 to 5, do not list a hand-preference milestone.

Is switching hands at 3 or 4 normal?

Yes, according to the NHS sheet. It says it is common for children to swap hands during the 2-to-4 stage, while a preference is still developing. A 3-year-old who colors the sky with the right hand and the grass with the left fits that description.

You may notice a few everyday reasons for a swap:

  • The crayon was closer to that hand. Young children often pick up with the nearer hand.
  • The hand got tired. Coloring is hard work for small muscles.
  • The picture is on that side. Reaching across the body takes practice.

The first two come from the NHS sheet's own advice, which suggests placing things in the middle and offering rest breaks.

Later on, the picture changes. The Raising Children Network lists swapping hands while drawing or writing during the first year of school among early signs that a child may need some help with handwriting skills. That is a reason to mention it to the teacher, not a diagnosis.

Should I put the crayon in one hand?

No. Both the AAP and the NHS sheet say not to choose for your child. The AAP says there is no reason to encourage a child to use one hand more than the other. The NHS sheet says that if a child does not yet use one hand as the preferred hand, do not choose or force one.

What the NHS sheet suggests doing instead:

  • Offer things at the middle. Place the crayon, spoon or toy in front of your child, at the center, so they pick the hand and not the nearer side.
  • Watch quietly for a few days. Notice which hand is used more, or seems more skilled, for drawing, cutting, brushing teeth, eating and play.
  • Once a preference is clear, back it. Encourage your child to use that hand consistently, whichever hand it is.
  • Name the jobs. Talk about a "doing hand" and a "helping hand." The helping hand holds the paper.
  • Finish with the starting hand. If the hand gets tired, pause and shake out the arms, then carry on with the same hand.

The Raising Children Network is direct about left-handers: when children choose their left hand to write with, there is no need for them to swap hands.

How do you set up paper for a left-handed child?

Tilt it, and keep it on the left. A left hand moving across the page covers what it has just drawn, which makes it harder to see.

  • Tilt the page so the left-hand corner is highest. The Raising Children Network says this helps a left-handed child see what they are writing or drawing.
  • Keep the tilt moderate. An NHS occupational therapy worksheet from West Suffolk in England says the paper should be tilted no more than 45 degrees (West Suffolk NHS Foundation Trust).
  • Put the paper on the drawing-hand side. The same worksheet says the paper should sit mainly on the same side of the body as the writing hand.
  • Mark the spot. Once you find an angle that works, the worksheet suggests marking it on the table with tape.
  • Hold the pencil a little higher. It suggests a grip at least 3 cm, a bit more than an inch, from the point, so the child can see the marks.
  • Seat left-handers on the left. A left-handed child sitting to the left of a right-handed child will not bump elbows.
  • Move the paper up, not the arm down, so the forearm stays supported on the table.

These tips were written for handwriting at school. They work the same way for a coloring page at the kitchen table.

Smudging is the other common complaint. The worksheet suggests fast-drying pens for older children. For coloring, crayons and colored pencils do not smear the way wet marker ink can.

Do left-handed kids need special crayons or scissors?

Crayons, no. Scissors, yes.

Crayons, pencils and markers are the same for either hand. None of the sources we read suggests a left-handed version.

Scissors are different. The West Suffolk NHS service lists "ensure left handed children have access to left handed scissors" first among its strategies for a child who struggles to hold scissors correctly (West Suffolk NHS Foundation Trust, scissors). If your child cuts with the left hand, tell the preschool or kindergarten so a pair is on hand there too.

When you show a left-handed child how to do something, it can help to sit facing them so your right hand mirrors their left. That tip is ours, from practice, not from the sources above.

What if my child still has no preferred hand at 5?

Some children take longer. The NHS sheet places a clear preference between 4 and 6, the AAP says many children do not show one for several years, and the AAP also notes that some people are ambidextrous.

In the meantime, keep offering crayons at the middle, and give the hands plenty of two-handed jobs. The NHS sheet lists drawing and coloring, cutting, gluing, threading beads, building with blocks, stirring and opening lunch boxes as activities where one hand does and the other helps.

If your child has started school and still swaps hands for drawing, the Raising Children Network lists that among early signs that a child may need some help. Start with the teacher, who sees your child draw every day.

When should you ask a doctor?

Whenever you are worried. You do not need a specific sign.

You will find blog posts that call a very early hand preference a "red flag." We did not find that statement in the official sources we opened for this page, so we do not repeat it as fact. If your baby or young toddler seems to use only one hand, or avoids using one side, ask your child's doctor to take a look. Only someone who has examined your child can say whether it means anything.

More generally, the CDC advises talking with your child's doctor and asking about developmental screening if your child is not meeting one or more milestones for their age, has lost skills they once had, or you have other concerns (CDC milestones).

For how the grip itself develops, see pencil grip by age. For drawing and coloring milestones, see when kids start coloring.

FAQ

At what age can you tell if a child is left-handed?

Some children show a clear tendency by 24 months, the AAP says, and many do not for several years. An NHS therapy service places a clear, settled preference between 4 and 6.

Should I correct a left-handed child?

No. The AAP says there is no reason to encourage one hand over the other, and the Raising Children Network says children who choose their left hand do not need to swap.

Why does my 3-year-old color with both hands?

An NHS therapy service says swapping hands is common between 2 and 4, while a preference is still developing. Offer the crayon at the middle and let your child choose.

How should a left-handed child tilt the paper?

With the left-hand corner highest, according to the Raising Children Network. An NHS worksheet adds a limit of about 45 degrees and suggests keeping the paper on the child's left side.

Is being ambidextrous a problem?

The AAP describes it simply as using both hands equally well and does not present it as a concern. If you are worried about your child's hand skills, ask your child's doctor.
