My parents didn't mind. Since childhood, they used to tell me that I can choose my profession freely. I tried with medicine. Burned lots of €s and lots of time. And then switched to IT. Parents did not get in my way - on the contrary, helped me wherever they could. And allowed me to shoot my own foot whenever I was so stupidly determined to.

I believe it's the best kind of parenting -- allowing your children to make their choices, their own mistakes and learn from them while suggesting a piece of advice along the way.
