I'd disagree, most of the time contact can be avoided and given the pitching speed of your average 9 yr old I'd say nearly 100% of the time it can be avoided. The only time a kid is really going to have trouble getting out of the way is if they are squaring to bunt which is a difficult position to move out of quickly.Teach her how to get hit by a pitch. Don't lie to her and tell here she can get out of the way.
My problem with this method is you go from a fairly thin profile facing the pitcher with a mask protecting your face seeing the ball and having an opportunity to move away from the ball to according to your cues above turning your back on the ball, tucking the back of your neck (which you now have exposed to danger) I can guarnatee if you turn towards the cathcer and put that wider profile facing the pitcher you will get hit more often and I don't care what deflection angle you create with your back that will hurt.The best approach I have heard is the the "turtle":
a.) tuck in the neck
b.) tuck in the elbows
c.) hunch the back
d.) do all of the above while turning towards the catcher.
