9 years, 9 months.

Dear Holly,
Last week while Grandma was visiting and staying with us, in part so she could see me perform in the play, she stayed in your bedroom; which meant I was gracious enough to let you sleep on the floor of our bedroom on a blow-up mattress all week.
You made yourself at home, even setting up a special corner for one of your stuffed animals as well.
I think it was like a fun camping trip for you!
Love,
Daddy
