My Dad pops in if he's in the area, though it is very rare that they go to the toilet while I'm at work but if they do they go by the back door, I have a tiled floor in the kitchen so is easy to clean up. As they get older I may use a day care service, there is a very good one near where I live and they are happy to come to your home for an hour a day to take them out for a walk or just for company. I am hoping to start working from home for 4 hours a day in the next couple of years so hopefully I wont have to use anybody else. I cant wait to be at home more, although it does worry me that I'll never be able to get any work done!
