Hand Dominance: When Will I Know, What Should I Do?

by

mother son writing

Ninety percent of people, more or less, are right-handed, and around 10% are left-handed.

Hand dominance simply means that a person prefers to use one hand for most things involving motor skills, especially smaller, more intricate skills.

Ninety percent of people, more or less, are right-handed, and around 10% are left-handed. The tendency toward using a particular hand may be genetic, but there are multiple genes involved. It is not a straightforward trait like brown eyes. If you are left-handed, your child may or may not be left-handed too.

There is absolutely nothing wrong with children or adults that are left-handed. It was once believed that being left-handed meant there was damage to the brain that forced a person to use the left hand. We now know that is not the case.

People use the hand that they prefer for fine motor skills, as well as other things. A person can be left handed and do most things with that hand, from writing to throwing a ball to brushing their teeth. Other people do only some things with their dominant hand, whether it is right or left. The ability to use both hands equally is called being ambidextrous.

    My 7 year old prefers his left but does certain things with his right. This is great but can be confusing when trying new things like sports baseball for instance he uses normal glove but he has choose that he he is in love with golf n found that he preferred n hit better with left handed clubs he eats n writes with left but throws n catches with right hand

    Seriously, I don’t know why more people haven’t tried this! I earn up to $500 per week. And what’s awesome is Im working from home so I get more time with my family. You’ll need a computer, an Internet connection & a can-do attitude. View it now Buzz95.com

    My son has shown left hand dominance since about 12 months of age. We tried to get him to be a bit more ambidextrous by simply putting utensils to his right hand. Again though, at 18 months, he has returned to the left hand. I wish he were more receptive to being ambidextrous. Then again, there are many other things that take precedence in life!

    I have a feeling our son is going to be left handed (just my luck), but I am very happy about that. It gives me a chance to try to learn something, and when he’s older I can use his left-handedness as a tool to have him “teach” me to do something.

    Thank you for this article. I am going to try the shoe tying trick with my daughter. I am left-handed and she is right. It does look like one of my twins will be left handed though. We still have time to see if one is.

    I am right-hand dominant, but my son, 15 months, shows a prefrence to his left. He uses his right occasionally, as if to test how it feels, but quickly reverts back to left.

    I am ambidextrous and I am already seeing my boy follow me… He uses his right hand to throw a ball or use a fork, but his left hand to grab for blocks, eat crackers with, or pick up small things. He is only 18 months old so I’m sure once he gets more into coloring and writing, he will choose a preference.
