... two incidents in this context. One was with my then girlfriend/subbie. One night, her baby - about 2 yrs old at the time - woke up at probably the worst moment. My subbie was heavily tied, and I felt the situation did not really warrant my cutting off all the rope, so when the baby would not stop crying, I took of my fetishwear and went to take care of him. It of course killed the scene, especially as "mummy" was quite vocal about why I would not let her take care of the child.
The other incident took place long after we split up, but since we are still on talking terms she told me about it: her baby - about five at the time - surprised her and her then dom partner, while he was literally hitting the living daylights out of her, saw his mummy crying at was quite disturbed, to say the least. It took them ages to quiten him down.
So, why do I tell you all this? Basically, to give you an insight. The bottomline is: shit happens, you cannot plan for every eventuality, but that should not keep you from planning ahead as best you can and if something unexpected happens, at least one partner should be in a reasonable state of mind to cope with it.
