Re: When did/would you let your child go to a sleepover? (non-family)
Unless the parents communicate about it, there are no plans. I wouldn't worry about it unless you hear from this mother directly. Do you even have a way to communicate with her? Know where her home is? Have done any other play dates?
FTR, DS was 3rd grade when I first let him spend the night with a friend. It was a neighborhood child we have known for years and who has played with DS for years as well. Weekend time is limited for us with DS since he goes to his father's the 1st, 3rd, and 5th of each month, so I've been stingy with my weekend time with him.
