I like to know that my kids are under my roof safe and sound when I go to sleep. Unless the sleepover was at someone's house whom I really knew well, and trusted implicitly, the answer is "no" when my girls are asked to sleep over. Luckily, this hasn't come up too much yet, and maybe by the time it does, I will feel more comfortable with the idea. Maybe. But if I don't, there is no reason to say "yes" to a sleepover and then worry all night. There will be plenty of time for that when my girls go off to college.
