Would you allow your preschooler to go for a sleepover?

I think there are a lot of factors to consider. The most obvious being whether the child is ready to go for a sleepover. Will he/she be able to fall asleep in unfamiliar places? How secure he/she will feel in the friend’s house? How well do you know the other party (because they will be the ones who will have to handle your child if he/she becomes nervous or anxious)? Personally, I would probably only consider sleepovers at school-going ages. The child will be better able to know what to expect and it would probably be a more enjoyable experience (feeling all grown up being able to spend the night away from home) than it would be for a preschooler (who may end up feeling anxious). For preschoolers, I would suggest more play dates with other children where the parent is around to attend to any emergencies. Just my personal take on this issue.
