My DS age 5 has a best friend at school. They get on great. Best friend had been to our house for 2 successful play dates. Only trouble is he's never been invited back. Best friends mum has been taking her son to the park after school to play with other children from the same reception class. Once again my son hasn't been invited. Am I over thinking this or should I say something? Perhaps I should ignore and just carry on inviting her son over. It's really odd I have to say. X
