I've found myself in the position where I am hosting a play date for my daughter and her 5 year old friend in a couple of Sundays time. I haven't ever had one before where the parent doesn't stay. What would you expect to happen on this play date? It's 3 hours long. Do I need to set up activities? What activities? Or do they just play free style? What sort of lunch should I offer is sandwiches ok? Should I be closely supervising for 3 hours?
