I'd have to say, finding time to be alone for some play time. Or even simply sunggling on the couch. *grins* Kids have an internal alarm system for that.. "OH NO! Mom is doing something! I have to mess that up!" lol
Never really thought about this one. But as the mother of two daughters, no. I don't think I would mind at all. As long as they were safe and happy.
As for my kids knowing about my lifestyle, no. They don't know on a conscious level. I'm sure they see the dynamic of the relationship, but it doesn't register to them as anything but just the way things are in our house. I don't call my Master 'Master' in front of the kids. I call him Love, which means the same thing to us.
Yes and no. For us it's slightly different. I have two children from a previous marriage, and so does he. However, taking care of the kids, mine or his, does feed into my submissive aspect. I enjoy serving him and the kids at the same time.
