Dd2 has just started school, and her birthday is coming up soon. She doesn't know enough names to tell us who to invite, and as we're new to the area we don't have any idea who anyone is either! My solution is to book a supervised bouncy castle party (with tea included) at a local sports centre - it can accommodate up to 30 children, so we can just invite all the everyone in her class. But now I'm wondering if there are any potential pitfalls to my excellent scheme. Has anyone done this and it's been fine? Or not? I will have to write 'sorry no siblings due to limited space' on the invitation - anything else?
