I find that the way I learn style changes frequently. For example I will go through periods where I pick up things by reading. After a while words blur into each other and I stop learning from reading.
A little later I find I learn a great deal by doing different things, but that eventually stops. Last year, I found that I learned from podcasts, now they blend into each other.
Based on my experience, I think it would be damaging to assume to know the learning style of a child, and that the best approach would be to keep materials on hand that encourage children to investigate different learning styles as they go along.
