I have a separate daycare space in the basement and I know I couldn't do it any other way. Our basement used to be an apartment so I have my own daycare kitchen, bathroom, landry facilities and separate entrance. I would have difficulty trying to maintain my home's cleanliness to the standard I have for the daycare space and I am a pretty private person so I don't want families/kids in my home either.

2 negatives- I don't' like that I can't start my supper/do minimal housework like other providers can (unless I better equip the kitchen and bring down a ton of stuff.)
I don't have a view of the backyard from inside the daycare so I can't leave them even for a second to grab something (at least I am not comfortable doing so)
