Start with organising the way the kids will spend the night. Decide on what they will be doing and what not. Do not leave it on the kids to choose. You must have a close watch on what they are up to.
When the kids arrive, ask them to get organised right away. They should have their sleeping bags organised. If you have started late, ask them to get comfortable and change for the night.
Arrange treats and snacks for the kids. You do not want them to worry you every minute. Give them a complete outline of their snacks and treats for the night.
To make it fun for the kids, bring videos or movies. Make sure you are not making them watch movies not suitable for their age.
You can add video games but that might take away the charm of a slumber party. You do not want the kids to stay busy in their own, especially if their parents are there too.
Add board games to the show. This would ensure that the kids are having fun and at the same time others are not getting bored.
Keep a check on what they are doing. Do not let them loose. You never know what your kids might do when unleashed.
Arrange for breakfast. Early morning the kids would need to eat. You should be ready with your breakfast as soon as they wake up.
For kids who are either too young for such parties, make sure you arrange something special. If you have toddlers in the house, make sure they are not being bothered by other kids or the noise.
