How to plan a sleepover is pretty easy just follow these steps!
Step 1: Food
First you want to focus on food . Don't try to go over board. They'll think you try to hard. So maybe some pizza or hot dogs are a nice thing. For older kids(13-16) try something like hamburgers and fries or ribs and chips.
Step 2: Entertainment
You need to find a way to keep kids entertained so try a movie.
5-10: try barbie, smurfs, or maybe dinosaurs.
11-16: ant thing rated pg
Or it depends on what your child likes
Step 3: Bedtime!
No one loves bed time but if your guest has to leave early I would suggest a bedtime at about 9:00. If they don't have to leave early then 11:00 is a good time.
