Hi M.,
I have an only child (5 y.o.) and so I think she is learning some important lessons from play time with friends, not to mention it's just nice for her to get a break from me. I try to ensure that the kids she plays with are from families that have similar values and standards of behavior. Even at that, we usually keep it to 2 or occasionally 3 times a week even though her desire for play dates is insatiable! Kids develop their creative abilities by spending unstructured time playing on their own as I have to remind myself and her when she's begging for more 'friend time.' It's hard putting a lid on it, but you can do it!
There are a couple other pertinent questions to ask, such as, are you in a situation where these other kids might be lifelong friends? Does your son have siblings or cousins who will be that link to childhood for him? I still remember the neighbor kids I grew up with - they helped make me who I am today. How do you want to manage that for your son's best interests. You want him to feel at home in the world with strong relationships with both family and friends.
The other question is what are you willing/able/desiring to give those other kids? If they're over every day is it because they are soaking up some of your mothering because they aren't getting enough of it at home? Time and time again I hear of the mothers of friends making huge differences in the lives of kids from difficult situations. Maybe that's part of your opportunity here. Or maybe it's a situation that's just weakening your family. Obviously I don't know the answer to that, but I'm sure you do!
If you do cut the friend time be sure to have some alternative activities at hand such as science experiments, craft projects, books, sports that can be played solo etc. or else the tv becomes the next 'opportunity' for boundary setting.
Best wishes to you!
