Tomorrow-day and other phrases coined by kids

I'm not usually one to glorify my kid's syntax mistakes, but I just love one of Kay's expressions. Every time she asks me for something and I say no, she asks, "tomorrow-day?" to which I usually answer, "Yes, sweetie pie, tomorrow-day you can do that."

And at five-years-old, Kay knows that tomorrow and tomorrow-day are not the same thing. Tomorrow-day is everything that could be and should be in Kay's little kid-sized world.  And I do hope, really hope, that just a few of our many tomorrows live-up to the expectations of a tomorrow-day, too.

Do your kids have a tomorrow-day phrase they coined that you just love?
