I’m not opposed to play dates for my dc (10 and almost 9), as long as it is with someone we know very well and are friends with the parents. There are maybe 3-4 families that I would be comfortable dropping my kids off for a playdate without staying there myself. That’s not just for safety’s sake; it’s also because I genuinely love hanging out with these moms just as much as my kids love hanging out with their kids.
As far as going into neighbors’ homes, I don’t think you’re being overprotective, and if that means your kids feel left out, well, so be it. I’d much rather my kids feel left out than ignore my gut feeling and something happen to them or them be exposed to something harmful.
I’m not a fan of separating my kids either, but I think it is unfair to totally not allow one child to have friends if the other one can’t be included. I have one boy and one girl. I can’t imagine my son having another 10yo boy over to play and telling him he absolutely must include his sister in the Nerf war or Lego building. Mine are at an age where having friends of the same sex is very important to us, for safety reasons, among other things. If our son is having a friend over to play, I will also try to arrange for our daughter to have a friend over as well. All of our close family friends have both sexes of children, so it is nice when we all get together.
As for your child’s age, I do believe that 6 is too young for unsupervised play dates, going over to neighbors’ houses, or other scenarios where your child would be without you. In your shoes, I’m less concerned about sibling separation and more concerned about common sense and safety. A 6yo is still very gullible and accepting of others–sometimes to their detriment. My 10yo son has much more common sense, street smarts, and a greater sense of awareness than he had at 6. It comes with experience and age, in my opinion.
All that said, I’m still the mom who wouldn’t dream of sending her children to church or other camp without me, no matter how old they are. I’m very protective! If we don’t know a family extremely well, I don’t even entertain the thought of my children being in a home without me or Daddy present. Our children aren’t allowed sleepovers and don’t even attend birthday parties or baseball practice without us. My husband and I make ourselves available to be involved in their lives, and so far, they haven’t complained at all. In their lives, my children have spent the night at 4 places without us: my mom’s, my in-laws’, my sister-in-law’s, and my husband’s uncle’s (just this past December). I love what Rachel said above about not separating parents and children habitually, because then it just seems easier to do when they’re teens and let them go off alone.
Blessings,
