Raising happy, confident kids is the goal of most parents. Some parents struggle to find ways to talk with their children to promote happiness and confidence. I recommend using a combination of communication phrases that promote acceptance and develop a growth mindset.
Being accepted for who you are by your parent or parents, allows kids to feel safe enough to develop healthily and to thrive. Growth mindset helps kids try and learn new things, to persist, and also deal with difficulties in a more flexible way. Growth mindset is also important for thriving in life.
