I think you are on the right track...you want to write a book about a kids perspective right? That's a great idea, maybe you should start with one solid topic, or make up a story but if you wanted to do it on different things, you could by doing short stories and placing them into categories...
If you have dance shoes I would wear those, but anything comfortable to work out in would be good. Wear loose fitting clothes or work-out clothes that are comfortable. I would bring a water bottle.
I think everything you listed sounds great!
Have fun!
My husband and I are planning on having our first child and we have been going back and forth with baby names. My husband is Irish and I'm Polynesian. I want a name that kind of represents us both.
Boy- Ronan (Irish)
Girl- Kamea (Hawaiian for precious one)
or
Boy-Logan
Girl- Rowan
