It is difficult for children to distinguish between truth and lies in childhood.Children between the ages of 3 and 7 years lie a bit more because at this age they are unable to differentiate between truth and lies. They put their imagination into words and give it to others by giving it the form of truth. This does not mean that your child has started lying.
For this, you have to introduce him to reality. Fulfill his observable wishes and make him understand what cannot be done. Parents and teachers need to maintain transparency in their behavior. If you do any Promise with your child, then definitely play it. Make them realize that if you believe in them then they will not do any wrong thing and even if they make a mistake, they will not be afraid to tell you.
They will take your permission before doing everything and always tell the truth because they are not afraid of you but believe in you and know that you will do everything right. The child's first role model is his parents.
