One must respect a child when they say “no.” If their refusal is in direct opposition to their safety, of course, this doesn’t apply. But if you never allow a child to carry out their own will, you’re teaching them to consistently carry out the will of others.
And although that may, at times, be a useful skill, it is not a rule they should cling to for a lifetime, it stands in direct opposition to their freedom.
Unfortunately, I learned this firsthand.
