My little boy turns 4 next month. Today he came out of preschool and told me everyone he asked to play with today said no to him, so he was alone all day and had no friends. He got really hysterical saying only his family like him but nobody at nursery likes him. I was trying to reassure him and telling him what a wonderful little boy he is, pointing out his friends. He'd say "James" used to be my friend but he won't play with me now. He was so sad and it broke my heart to see him so upset. I've told him tomorrow to just join in with people, he said he's tried that and they just walk away. I've spoken to the nursery staff before and they just say he's fine and likes playing by himself, but he doesn't. I'm crying for him. Any advice please, has anyone had similar?
