Patty,
A very wise man (me...yeah, I'm humble too) once said "A pat on the back is only inches away from a boot in the ass."
There is a lot of truth to this. One of lifes great lessons is often a humbling experience. Kids spend the first 10 or so years of their life getting praise (rightfully so) for every new experience... i.e., first steps, first day of school, first tooth etc... Unfortunately, as much as we praise our kids, it sets them up of unrealistic expectations in the real world. Not everyone thinks kids are as cute as their parents do. At some point, the cute factor wears off and some real talent and hard work have to step up. It sounds like your kids are at that point.
I am not implying that your kids aren't cute or talented, I am merely saying that it might be time for them to start learning to stand on their own a bit.
Needless to say, I hope they do well and get through it ok.
