Hi
We have booked for dd and 7 friends to go to the circus for her 9th birthday. She will be inviting 4 girls from her class and 3 from another class, however there are 7 other girls whose parties she has been to this year who we can't invite due to costs. I feel bad 
Do you think I should arrange another small party for them (seems mad but hate upsetting people) or is that just the way it goes??? Dd has obviously had a good year for party invitations...(it is a large school!)
Also - do I need to do party bags or can I get away with a piece of cake and sweets for the circus????
Thank you!
