My 4yr old DS has been invited on a play-date, the little boy is very active but is also quite possessive of my son e.g. won't let him play with other children at nursery. The friends mum is lovely and she has invited him round, i left it open so i could ask DS but he doesn't know want to go, how do i tell her without making it sound like i don't want him to go round?
Advice would be greatly appreciated.
