Am I taking the right path?

As a mother, I have left all assignments on the elder one to do it herself. She manages it quite well, I am proud to say, she is responsible. We fill in only when she asks for help, though I do crib about that, too, since she calls us only at the last instant.
And today at the school exhibition, I was stunned, more by the labour parents have put in than by genuine kiddish efforts on the project.
The kids, the poor ones, were good by themselves, trying to explain everything verbally, but some of the projects, were truly the hard work of parents and in some cases even by carpenters or model makers at their best!
In an effort to be better than the rest, it is the parents who take it on themselves to finish the work of the students, and then some efforts like my kids does seem a little childish in the whole perspective of exhibits, though that is what these projects should reflect.The School should give projects, which needs only the efforts of the kids, and different ones for kids of their age and hence judge each kid on purely their own skills...
I am not the one to sermon, for I think it is more of guilt that is speaking, for I have not helped much to make the project a little more professional. Or is this a genuine process on my effort to make her more independent!
I am not sure, but the next project, I intend to do something more, though I am proud with what she did, since it was all her idea and her hard work.
