No Wonder They're Confused

After hearing these phrases over and over again all day it's a wonder the girls can figure out what they can and can't do at all.

-Don't sit on that!
-Sit down
-In your mouth, please (toothbrush time- apparently there is quite the temptation to brush everything in site)
-No, no, not in your mouth
-Eat it
-Don't eat that
-Go sit with sister
-Don't sit on sister
-Don't touch, that's trash/dirty
-Pick it up and throw it in the trash

Is it just me, or are we constantly sending mixed messages?
