Sorry, no, parents don't intrinsically know what's best for their child, and that's perfectly OK. It's OK to not know what to do, and it's undeniably right to seek those answers from others who might.
Parents thinking they always know what's best is why so many otherwise totally normal kids grow up to be totally fucked up adults.
