Encourage your child to explore their understanding of friendships and what they could do to make friends. e.g Smile, ask them if they want to play?
Talk to them about the different friends they have at nursery, home, dancing, football, etc. Ask them to name their friends or write their names for them to attempt to copy. Why do they like playing with that friend?
Ask them to draw a picture of what they like to do with their friends.
Explore feelings. What makes friends sad? What can they do to make their friends happy?
