Follow the Rules
Before you drop off children at a birthday party, they must be prepared to follow the rules at the friend's house. Explain that even though the party is happening elsewhere, they should act as though they're at home with mom and dad. Encourage children to listen to the other parents, since that will help the birthday friend have an even better time.
On the flip side, birthday kids must also follow the rules. Amid all the excitement of friends coming over for the afternoon, it can be tempting to show off or act out. But talk to the birthday boy or girl beforehand and discuss the importance of setting a good example. That way, friends will have more fun and want to come back over again.
