Don't make the mistake of thinking that because parties are so much fun the longer the better!
I know the children really look forward to parties and you want to make the most of it but please remember that children's attention spans can be fairly short and parties are really excitable, action-packed environments.
If the whole thing goes on for too long then the children tend to get tired and become
agitated. They don't enjoy the party as much and it's certain the parents won't either!
How to Avoid Having the Party Last for Too Long!
Two hours is the perfect total length for a children’s birthday party!
Please remember that for the children how much fun they have at the party is all about what they do not how long they are there for!
It seems that there is a consensus that's formed in recent years that parties should be two hours in total. This is just about the perfect length of time and it's what parents are expecting their kids to be invited to.
