I have the daycare on both the main floor and in our basement, as well as in a spare bedroom. It works really well right now because my own children are still young (2 and 4 years old), so having the play rooms on both levels of the house works well as it gets used after daycare hours. I also like the change of scenery for myself and the kids of having different rooms to go to during the day. I like being able to sit in the sunny mainfloor living room in the morning.

But we have our family room in the basement and the main floor living room is solely for the daycare, so my husband can go downstairs and I can be upstairs with the daycare kids if necessary (though I can't say my husband tries to purposely avoid them). We came from a very small house before the one we live in now, so the spaced used just for daycare isn't missed.

I don't know, I don't think I would want to change what I have right now to being only in the basement, even though it does feel like there are toys and daycare stuff all over. But I try to keep things organized, maybe it will change as my own children get older. I would probably think about what was best for MY day, as opposed to my husbands, since he isn't the one that is home in the daycare all day.
