Shea says, “Oh, shit” about every ten minutes now. Before it was “uh oh” and then it was “oops” and now, thanks to hearing me say it one time, he says, “oh, shit” every time he drops something, his ball rolls under the bed, etc. etc. How do I train him out of this? I have a plan to say, “What is this word ‘shit’? Do you mean, ‘uh oh’? ‘Oops?'” but I feel self-conscious saying it at all in front of our nanny, so wait until she’s not around.
