BDSM relationship --

    

How do you make it work w/ children or babies in the mix? I'm not in a BDSM relationship but started reading 50 Shades of Grey (I know, I know - needed a book to pass time and since my SO and I recently saw the movie, I said why not). I find that sort of lifestyle interesting for some reason. I understand it isn't for everyone, so please, no rude comments. I would just genuinely like to know how mama's make it work, as it seems harder to maintain a relationship/ lifestyle like that with children. This isn't something I could do, my SO would never agree to anything like that anyway, I'm just really curious. And sorry in advance if this offends anyone in any way.
