Generally speaking people are one side dominant,so right handed, right eye
dominant and right foot too.
However some are cross lateral,might be right handed but kick with left foot.
And vice versa.
My O.H seemed to be left handed when he started school aged four ,
The teacher punished him and forced him to use his right hand and consequently he developed a severe stammer.
His Mum went into school and “dealt with “ the teacher.
He ended up left handed but right foot was dominant and he played oodles of amateur football, playing when he was in the army doing National Service.
However I think he would have been better left alone as he was so awkward with things like DIY,mixing stuff,stirring,it was obvious he would have been right handed when he matured a little and used his by then preferred hand.
Both the teacher and his Mum were wrong, children,especially as young as four have often not found their preference and left alone will do.
His Mum did not punish him of course but she thought ,as most people would he should use his left hand if he wanted. He said he almost felt obliged to use it as she had “dealt with” the teacher in no uncertain terms.
His handwriting ,left handed ,was beautiful,he was an accountant and in those days all ledgers etc were in copperplate.He ruined good fountain pens by the score and kept the pen hospital very busy.
My eldest son is cack handed and my granddaughter too ,but she iis not my
eldest son’s child, she is my daughter’s.
