Re: When did/would you let your child go to a sleepover? (non-family)
I will only let the kids sleep over at houses where i know the parents.
The boys just had their first sleepover at a best friend's house and they were 3 (close to 4) and 5. They had a blast and did not want to leave. The kids are all the same age. A few weeks after that, the oldest got to sleep at another friend of mine's house.
We grew up having sleepovers all the time and going to sleepovers often. Some of my best childhood memories!
