In the home school community we were associated with, no kid sat for five hours.
My kids did (on Saturdays)...they didn’t like it much, but a few swats when needed got them many years ahead in math.
Yup, no. We homeschooled too - my wiggly son lay on the rug in his pajamas to read. No desks, not a lot of sitting.
I see it's easy for all the non accredited doctors here to make diagnosis and prescribe treatment. how telling that so many think that beating a child is so much more productive than say, exercise or God forbid giving the child who is probably bored something challenging to engage their minds.
Nope the obvious answer to too many is beat the education in, how sad.
