How Do I Know if My Child is Right or Left Handed?
Hand preference appears when your toddler starts to use a spoon or various writing tools. As parents observe their child, they may begin to question whether he will be right or left-handed and how much influence they have over hand dominance. Research shows that “… by the eighth week of pregnancy, genes in the baby’s spinal cord already show the beginning of right-left preference – before the connection between the spinal cord and the brain is fully formed.” The unborn baby’s spinal cord is where hand preference starts! Have you seen an ultrasound of a baby in the womb sucking a preferred thumb?
You likely watched your baby use both hands to reach for toys and food. Reading and grabbing do not require specific muscles. Often babies will use the hand closest to the toy that they are trying to get! As fine motor skills develop, hand dominance is more obvious.
Children may begin to demonstrate a right or left-handed dominance around 18 months of age, with a more developed hand preference by 3 years of age. Switching hands may still occur… because the hand muscles get tired! Right or left-hand dominance is usually well developed by kindergarten (age 4-5) and fully developed by First Grade (age 5-6). (Reference: Better Health Channel)
Why does it matter which hand is dominant?
- In kindergarten, your child will have many opportunities to draw, write, paint, and craft. Encouraging the child to use the hand that appears dominant will increase practice and improve the child’s performance.
- Since 90% of the population is right-handed, left-handed people do experience some practical problems. (e.g., modeling pencil grip, scissors, learning to use utensils, or tying a shoe!)
How should a right or left-handed person hold the pencil?
My sister uses her left hand. Our knowledge and awareness of handedness have improved over the years. Because English writing runs left to right, Cathie learned to ‘crab’ her hand as she wrote… to avoid smudging the ink. Today we know that both a right and left-handed child should hold the pencil with a tripod grip.
Suggestion: Ask the child to wiggle his fingers, then hide the last two fingers from the thumb by tucking them in toward the palm. Hold the pencil with the thumb and first finger. Make the knuckles move in and out just like “froggy legs.” Use the third finger as a “log” for the frog to sit on (so the pencil does not fall to the ground). This position is the same for right and left-handed people!
Modeling for Right or Left-handed People is Important
- If you demonstrate writing, eating with a fork, tying a shoe, etc., please remember that modeling is important.
- As a right-handed parent or teacher, modeling works well for right-handed children. But, if you are modeling for a left-handed child, use your left hand … and don’t rush! (The reverse is true for left-handed parents and teachers!)
- Just picture a “southpaw” trying to mirror a right-handed person recording letters and sounds … or demonstrating how to tie a shoe!
Sometimes left-handed children learn to write ‘back to front (mirror writing). “This is a natural inclination, not a sign of dyslexia, and will resolve given time, practice, and encouragement.”
Right and Left-handed Scissors
- When a child enters kindergarten, the teacher assesses hand dominance to maximize student learning opportunities. Schools have both right and left-handed scissors. Have you ever tried to use right-handed scissors in your left hand?
- Home and school need to provide left-handed learners with scissors design for left-hand use. Right-handed scissors have the sharper part of the blade on the left side. A leftie will try to use them with his left hand. Frustration sets in because the dull part of the blade won’t cut the piece of paper or string. (Even though the child is trying to do as asked.) Imagine how that child feels through no fault of his own! The scissors do not work!
Bonus for Lefties!
Left-handed people are often at an advantage in a wide range of sports! Why? It could just be the unexpected left-hand follow-through. (e.g., tennis, baseball)
Right or Left Hand Preference Assessment
- The following activities are often used in a kindergarten classroom to determine right or left-handed preference.
- This is still a good guide, but please note: the Better Health Article states that while, “It was once believed that a right-handed person has a general dominance on the right side of their body, which means thy favored foot, eye, ear on their right side, It is now known not to be the case. Many people may be right-handed but take their first step with their left foot.”
- They determined that the more we discover about right and left-handedness and their links to brain function, the more we realize we don’t know. Your child may throw a ball with a right hand, use the right hand cupped to the ear to listen more intently, but kick with his left foot!
- If hand preference is not obvious, you may want to observe the child’s response to some or all of these activities.
- For each of the activities used, check whether the child uses the right side or the left side.
- When you have completed the activities, you’ve chosen to use, review the results.
- If you need to clarify your observation of the child’s hand preference, just pick one task from each grouping.
- Optional: Randomly introduce and observe one or more of these tasks throughout the week. Record the results.
- small ball
- toilet paper roll
- cup of water
- Place a plastic/paper cup of water in front of the child. Ask the child to pick up the water as if to drink it. Did he use his right hand or his left hand?
- Place a soft ball in front of the child. Ask the child to pick up the ball and throw it! Did he use his right arm or his left arm?
- Put your hands behind your back, with one hand holding the other. Which hand is doing the holding?
- Imagine a bee is flying toward your face. Which hand do you use to shoo it away?
- Place a toilet paper roll in front of the child. Ask the child to pick up the tube and look through it. Did he use his right hand or his left hand? Which eye was used to look through the empty tube?
- Ask the child to pretend to be a pirate! Close one eye. (Optional: Use your thumb and index finger to create a telescope.) Which eye was kept open?
- Pretend you are hard of hearing. Cup your hand to your ear to make the sound louder! Did he use his right hand or his left hand?
- Place a ball on the ground in front of a child. Ask the child to kick the ball. Did he use his right foot or his left foot?
Remember: Handedness is not always cut and dried. People can still swamp hands for various tasks.
