My DS has just had his fourth birthday and we invited sixteen of his friends from nursery, all chosen by him. I was shocked that a few famillies did not even reply despite a gentle reminder a week before the party. My DS was not fussed about who came other than his few special mates but I needed approximate numbers for the softplay. The majority of parents replied with loads of time but others didn't even respond. I had my e-mail address and mobile number on the invitation. AIBU to expect other parents to model good manners for their children ?
