I tend to include them in our day. I hand them papers to pass out to the kids, make them sit at circle time with us and sing. If they are here during snack time I have them pass out the lunch boxes and help open juice boxes, ect.
I can't stand someone just standing behind me watching everything I do but I am always up for an extra set of hands! 
I would be scared to death to have a complete stranger sit that close to my daycare kids. The liability would be waaay too much.
And my food program and licensing would have a fit if I allowed someone without clearance and a current food handlers permit to pass out food. Hepatitis anyone?
