How can I make my child open up to me and share their mistakes?
Be a friend to your child
Treat even small children as friends, so they are free enough to tell you their matters. Talk to them lovingly like a friend and give them the right direction. If you explain again and again, children going down a wrong path can mend themselves.
Parents should behave like friends even with small children, and make them so free that they can tell you their things and you can give them the right direction.
