My son who is 6 is a socially anxious child
we went to a friends house yesterday and he couldn’t speak wouldn’t say please or thankyou and was coming across extremely rude . They gave him a jumper as a gift and he just threw it , I was so embarrassed but I know it’s because he doesn’t want any attention drawn to him. He acts silly and sometimes shouts when he’s feeling nervous . What can we do to help?
