The only one I can think of at the moment is: My bra is not a hat, please take it off.
I know there are more, though!
-The dog is NOT a horsie! (As my 20 month old tried to ride on our 14 lb dog)
-NO!!! Don't eat the tick! It's not a jellybean!! (gross. It happened last easter. The older kids were eating jellybeans and the baby didn't have any. She was so happy when she found this grey jelly bean shaped thing on the floor and I caught her as she almost put it in her mouth. Knowing she didn't have a jellybean, I ran over to see what it was...it was a bloated tick that had fallen off the dog. OMG, I about puked.)
-Really, child, you're not a dog so stop eating like one. (to the 6 year old who apparently would rather eat like a dog than a person.)
-That is NOT a potty chair!!
And on that note...
-Please get your snack out of the potty chair!!! BEFORE you sit on it!
