WHAT did she just say?! Oh my!

WARNING BAD WORDS AHEAD!!!

Today Madaya and I were running around the house playing. She stopped and ran off to her room, running back down the hall she heads towards me saying " cock mommeeee cock " I was mortified and asked what she said, to slow down
She says.. " cock cock mamma cock " I about flipped... for it sounded just as it was really that.
I got up to see what she was talking about, and she ran off,
about 2 minutes later she comes out again, and with great laughter says see momma daddy cock cock mommeee.... ( yes, shes building sentances ) I said daya dont say that and she looked puzzled and held out her box of CHALK!!!!!

So were working on it. Could you imainge " daddy cock daddy cock! " AHHHH i would be mortified if people heard it.
