Why is it that the words "Oh my gosh!" sound so much worse out of the mouth of a four year old than that of a thirty-two year old? I find myself not wanting my children to say phrases like this, yet I say them. What's your house rule? I find myself asking them not to say it. What exclamation should they say? And what on earth am I going to do when they are eleven and try to say something much less tame than this?
