We got a wii yesterday. Aubrey (5) and I got really into making miis for everybody in the family, including Baby Sadie (18mos). (A mii is an avatar, or image you make of yourself. You can choose different face shapes, eye color, etc. It is hilarious how much you can make a mii look like someone.)
At any rate, we were working on my mii, and I made myself super tall and skinny. Aubrey looked at me and said while laughing hysterically, “Momma, I think you need to be a little fluffier!”
ROTFL
I have heard similar things from my brood 
The most recent was (after I got dressed up for an office meeting as opposed to my home-studio denims) "Mom, you look all fake."
We were at a pre4th of July cookout tonight. As I assisted my 4yr old with his plate he looked at mine and declared, "I think you have enough." Said from the same child that wanted me to allow him to have a cookie & cupcake for dessert.
Fluffier…hahaha! Gotta love kids!
Cheers!
