Five : probably, no, usually, why not?, no, yes (five questions over 24 hours from a four-year old).
1. Can we watch Chitty Chitty Bang Bang for Christmas?
2. Can we do some fireworks in the house?
3. Do guards really guard stuff?
4. Can I build a new house today in the front yard? Will you help me? Can we move all our stuff into the new house today?
5a. Can I make a recipe? I'll make dessert. Can you get the sugar for me please? Where's the chocolate?!
5b. Can you come read a book with me in bed? You can read Matthew Looney and I'll draw while you're reading.

I love good questions.
