At the bottom of my list would be relocating kids! After 20 years military service I can tell you it is your attitude towards it that makes the difference. It's like when a kid falls down, if you rush to them a ask 'are you hurt' they will react one way, if you say pick yourself up, you'r not hurt. they react another.
We moved our kids in elementary school twice, junior high twice and high school once, (summer before her senior year) Both turned out ok. In fact I think better for it. My guess is there are more than a few on here that moved kids just as much, or were moved just as much.
