Studies have shown that the best defense in a bullying situation is self-esteem. Cheer on your child, always let them know that you appreciate them in your life.
I just finished a book about a 19 year old young man who ran his first marathon in Chicago. He and his mentors set a goal to finish in less that five hours, he finished in 4:59 seconds. The young man was ecstatic and felt as if nothing could stop him from living his dreams.
If your child isn’t outgoing don’t try to make her do things you like to do. Instead find out what she likes then support her and cheer her on. Let her succeed on her own and watch her self-esteem blossom.
