Hand preference usually starts to develop by the age of 3 years.
Hand dominance should be fully intact by the age of 5 years 6 months old. By now your child should use 1 hand, dominantly, for all of the tasks he performs.
If you child is still switching hands to perform tasks there might me an impairment with laterality and/or midline-crossing.
Poor laterality has a negative influence on bilateral integration (using the 2 sides of the body together to perform 1 task) and/or fine eye-hand coordination.
Approximately only 1% of the population is truly ambidextrous – in all the other cases impaired laterality is present thus a child ends up with 2 unskilled hands.
To determine if you child’s dominance is fully intact let him perform the following tasks and note which side he prefers
- Put pegs into a peg board
- Switch on a light
- Point to and object
- Take an object out of a cupboard
- Draw a line using an rules
- Erase a line
- Unlock a padlock
- Open a door

- Touch an object on a wall
- Cut with a scissor

- Write his name
- Open the lid of a jar
- Pick object off the floor
- Use a knife and cut clay
- Use tweezer and pick up small objects
- Thread objects onto a shoelace
- Kick a ball
- Take your shoes off (which foot first)
- Hop on 1 spot
- Stand on 1 leg
- Kick a ball into a target
