Mostly we just live our life.
The one caveat is that our youngest daughter (21, 17, 13, 6) gets emotionally attached very easily.
So we have an agreement that new POTENTIALS don't meet the kids. Only at the point where someone becomes a serious prospect does that happen.
This agreement came after 2 of Maca's potentials turned into disasters. The resulting emotional turmoil of our daughter (they were both kind to the kids) wasn't worth it for us. Much easier to just wait until we know someone is at least going to be around as a friend before letting the kids meet them.
