Children are very vulnerable when it comes to defending themselves or surviving traumatic events. Unhealthy self esteem can influence the kid’s growth negatively.

A healthy self esteem is essential to the kid’s interaction. A few ways in which one can boost the kid’s self worth are:
Taking into account the kid’s sensitivity and therefore being artful with what you say to them
Create a positive role model as the kid is very likely to imitate your character
Dispel your child’s irrational beliefs helping them to set more accurate standards about themselves
Show your child affection. They are able to tell actions are from the heart
