Hello, after some advice about what to provide / expect from play date. DD is 3 as is the girl she has coming over. Her mum is also coming but as this is the first play date I have been involved in I don't really know what to do. 
They are coming at 10 in the morning. Does this mean they'll still be there for lunch? Should I provide activities for them to do? I was thinking of setting up play dough or something in the kitchen and then setting up a cafe style play area in the sitting room so they can have a tea party. Or am I best just letting them rummage through DD's toys? Also I'm not too keen on them going upstairs - is this normal?
Any advice is welcome so that this isn't DD's only play date!
