Wait, What Was I Doing?

I worry about Tot.  Before I get started I should say that she's an amazing kid.  She's artistic, creative, adventurous, and happy.  She's also impulsive, inattentive, and has difficulty expressing her emotions.  Before anyone reading gets their diagnosis pants on, let me share that I have an extensive background in education and all things disability related.  I know ADD/ ADHD, I know emotional disabilities and I know enough to know how to take my parent glasses off to see the real child.  So, let's not diagnose, shall we?
The point is, I worry about her.  We worry about her.  Let's address attention.  Her attention level has always been fleeting.  Last year she did well in school, but this year I'm already seeing instances where she doesn't follow directions or skips over questions.  Even when we work at home together, she'll start with number two, move to number five and I'll have to redirect her to go back and do the problems in order.  Getting her to follow multi-step directions is nothing short of a miracle.   It is no exaggeration that she can walk up the stairs with three things to do and maybe, maybe, get one done.  We've tried different strategies with her- checklists, repeating directions, shortening her task list.  It helps, but it doesn't alleviate the problem.
While it's annoying to us, so far it hasn't impacted her performance in school.  When it does, we will address it.
But, let's be honest, the apple hasn't fallen from the tree.  Have you met Bee?  Although he's gotten better with age, he easily gets swept up into a stream of consciousness whirlwind of activity.  Outside to mow the lawn- look some leaves- mower stops- search for rake- while searching for rake, a bee's nest is discovered- attention shifts towards spray for nest- sees a bolt that was supposed to be put back in tool box- walks towards tool box- opens and begins reorganizing- tools remind him that he needs to tighten bolt on upstairs desk chair....
