Potty Mouth Here We Come!!

Luis, Jace and I were on our way to Sam's and Luis was driving. He accidentally got in the turning lane when we needed to go straight and Luis said "Oh Sh!t" so naturally Jace immediately started to say it. Trying to keep straight faces and not laugh we told Jace that wasn't what Luis said and that he was saying it wrong and it was "Oh Shoot". Well the next thing you know we are in Sam's and Jace is in the cart and some of our drink spilled on the floor. Jace started saying really loudly "Oh Sh!t, Oh Sh!t" again and again. Luis and I are just mortified. There were people every where, most of them just walked by us laughing.
From now on with the advice of Luis' Mom we just tell Jace any bad words he might say are "grown up words". We know he will hear them all the time but hopefully from now on he will know he shouldn't use them!!!
