Siblings at parties

[jambot]

DD is having her 4th BD soon and I really don't want siblings, esp older ones coming, as they tend to take over the show. I am amazed by how many parents just show up with all their kids in tow for a party only one has been invited to. How do you make it clear on the invite without being rude?

"I'm afraid we are unable to accommodate siblings on this occasion"

To be fair though, it can be difficult to take a child to a party if there's no one to look after the siblings. Not everyone has any option. Mind you, I'd leave the invited child rather than stay with the siblings.
