My toddlers often focus on the building blocks to the exclusion of the drawing. I can cancel 5-6 times, tell it to do drawing as many times and it's still got building queued. The tables have been cleaned, I make the toddler do something else in between, still they won't draw. Not all toddlers, just some. I haven't noticed if there's any particular personality or hobby bent.
I have two sets of twins on different lots.......one of each prefers drawing to blocks, and the other two prefer the blocks. One set just grew up and the girl who preferred drawing and charisma activities loves cooking and food related stuff already. The boy who did the blocks and (ohh it's late..can't think right now) the old beat on the peg game skill, hasn't come up with a hobby determination yet that I noticed.
Just came to me logic?
After reading back a few more pages, her cooking must be inherited from her mother?
