My 8YO son regularly has friends round to ours, however he always turns down invitations from his friends. They are all people we know well, and he has gone round in the past and enjoyed it, but recently he refuses to go. I'm good friends with one of the Mums but I'm worried she is starting to take offence as I keep having to make up excuses. Should I keep trying to persuade him? Or just be honest with her and say he doesn't want to go to anyone's house and it's not personal? Has anyone else experienced this? Thanks
