Abstraction means to take the essence of something and try to display that. Figuring out how a crayon does look and feel is nothing like that. if the abstraction is taken from art itself and resubmitted self referentially as art that shows the performance (e.g. Pollock) or design and perception of proportions (e.g. Mondrian) then that reuqires having done some art before - I'm not totally convinced of their motives, but for sake of argument I would assume they underwent a considerable thought process of refinement. If a child does it as a novelty, it might achieve the same effect, but often not reproducibly - and reproduction is a huge factor of craft. Very correctly, if a child can do it, there's no high barrier to the reproduction. Although kids are free and random enough to be a huge source of inspiration.
