What makes a parent expert in deciding the best interests of his children? Question is related to parents wanting kids to be skilled at something or the other.

As a parent, I don't claim to be an expert in anything, but I'll look at her hobbies and interests to see what she likes. I'll also give her plenty of opportunities to try out new activities and sports to gauge her interest. I believe that it is more important to be passionate about something. From there, she can build on her passion and form a skill from there. For example, if a child is passionate about art, it would make sense to enrol him for art lessons to develop his skills and learn techniques. I wouldn't force my child to learn something against her interests unless absolutely necessary.
