Just keep practiceing and playing eventually your hand will have a feel for anything you want it to do,no matter what it looks like doing it.
Like said above its good that you can evan use it at all too many players baby there pinky and only use the other three.
I think useing the pinky lessons the load on the other three which is probably better for stuff like tendonitis(spell?)and carpel tunnel. Well this in addition to a few minutes slow warm up befor you play.
Not to mention you can hit more notes in a run when your using your pinky instead of just three fingers.
