I completely agree with society's expectations too.
Every professional's book says something different in how to raise a child, what's wrong and right, better or best. Everybody's opinion is better than the last, many parents strive to be that perfect parent. Don't ever tell your kid no. BS on that.
Don't want to hurt their self esteem so tread gently and don't be negative.
There has to be a firm enough line, given with a lot of love, acceptance, but kids still need to learn right from wrong.
