Would you allow your preschooler to go for a sleepover?

There certainly are many factors to consider for this: what place is it? Is the baby feels comfortable in going there for a sleepover? Are you comfortable with the people where he/she is going to go for a sleepover? If there comes a time when your baby needs you will you be able to reach in a quick time? Only after all of these checks I will allow my preschooler to go for a sleepover.
