A sleepover (also known as a slumber party or pajama party) is a social occasion where a young person stays at the home of a friend.
Typically a younger person will partake in a sleepover; however, an adult or older person may sleep at a friend's home.
The sleepover is often seen as a rite of passage for a young child or teenager, as they begin to assert independence and to develop social connections outside the immediate family.
[1][2][3] Beginning in the 1990s, commentators wrote about a perceived new trend of parents endorsing sleepovers for teenagers, with both boys and girls staying overnight together.
While some writers decried the trend, others defended it as a safer alternative to teenage dating outside the house.
