In general,
co-ed sleepover parties aren't a great idea for the tween age group.
All night
co-ed sleepover parties are not uncommon for teenagers as they are included in events like prom and graduation nights.
When can they have
co-ed sleepovers, go to parties, or date?
Also, I grew up in a home without many boundaries and I had many
co-ed sleepovers throughout junior high and high school.
In addition, many tweens and many parents find
co-ed sleepovers an uncomfortable social setting.
