Hi! My son will soon be six years old. Children a little older, say 6.5 years, don't want to play with him because they think he is too thin and small for them to play with. They also laugh at him and this really upsets my child. My son has also had fights with them as in hitting them and saying some bad words. How do I make my child more friendly and stop him from using bad words or hitting others? I want him to be very friendly and socializing. Please help.
