It would be nice to have nationalism as the theme of your child’s birthday party. You can send out Patriotic Invitations in your native language. On the invitation, you can request your guests to wear your country’s national costumes.
At the party, you can serve snacks that are considered as your country’s native foods. Then you can play songs that are sung in your native tongue. Your loot bags could include a miniature flag of your country or a map.
The party will open the eyes of your child and the guests about the cultural heritage of your country. That would be a really unique and educational party!
