This is poor advice. For example, I can compare a company that doesn't look at its books, thinking anything they'll do is better than the government.
So yeah, you are free, but it's not advisable to chance it. I have seen children who are highly intelligent and ignored: not nice!
I am convinced that any parent who cares will do a good job. If they feel they are unable to do some things, they will look for help and advice. I followed a rather laissez faire method of education, and all of my kids grew up to be confident, successful adults.
