My husband and I have been having a disagreement, lately. I am curious about what others might have to say on this topic. There are several children who live in our neighborhood down our street. Often, we take our 4-year-old out for a walk, at which point he sees his friends. Usually, the kids play outside while the adults talk, and all is well. Our new neighbors across the street allow their three children (twins who are 5, and a 7-year-old) play inside while they socialize outside. When we run into them, their children inevitably invite our 4-year-old inside (he is JUST turning 4 in a month, so I'm rounding up). My husband has been allowing him to play indoors with their children in their house, unsupervised (directly, at least), while he socializes with the neighbors outdoors. I get worried about this and would rather not allow him to do that, but it is a bit awkward to address with the neighbors. It isn't that I think there is anything out of the ordinary going on - but it just seems too soon to me to allow him to play inside alone for a half-hour at a time, particularly with other children in a new home. My husband's stance is that it is extraordinarily awkward to address with the neighbors (he doesn't want to invite himself inside their home when they feel comfortable allowing the kids to play inside alone), and he just isn't that worried about it. I am curious about what others have to say.
