A.; its perfectly fine to keep your kids at home,in fact wy not have the neighbors over at your house, see whats happening is while their kids have your kids over they parents get to relax, and dont have to watch their kids. i would definitely keep my kids in my yard, and watch them as much as possible, what happens when somehting goes wrong ? wll you have regrets thaty ou let yoru kid go over there ? things happen most when children are unsupervised, if you need to be with them as i did and they grew up fine and wonderful, then go with them and check out the neighbors yard, and watch them there, or keep them at home, i did that too, just for an hour , and then home, god gave the children parents for a reason, they need supervision, in fact its law that a child cannot be left alone i beleive in this state till 13, so unless they are 13 they should be supervised, and cared for, let the other parents do what they do with their kids but keeping your kids separate can help your children too, to be more obedient, and a more peaceful household, i dont think you are over protective i think your protective, and its a good thing, there is so many bad in this world definitely be protective, as a mom you should follow your gut insticnts when it comes toyour children, even if its hard to do, or the kids want to do otherwise, dont give yourself any regrets for later, take care , i raised 3 boys, and it was my house that held most of the kids, cause i too did not want them all over, we are happy and they listen more so to me than i can say other children listen to their parents, just have a wonderful day , and be happy, D. s
