Sailor Mouth *#$@!!

I hate to see people teach children to say bad things! I absolutely hate it, yet, my child has
decided on his own that he wants to say every bad word in the book. He's only four! He doesn't understand right? Except that he says them in the right context, tone, facial expression, etc. That is scary! Hilarious, but, not right. Something must be done, but, I am not sure what.
I know who I think are the culprits, but, really what can I say? Do you know how many bad words are in cartoons and children's movies? Watch one and count, you will be amazed! I have taken special toys away and it has made an impact, but, now he is bugging me about that. AAGGHHH! I can't win, so, what would Martha do? She would make a book with all kinds of ugly words in it that we can share with our loved ones. Each person can find the word that has special meaning to them and sign their name, or paste a picture of them so, the child will know
who says what. A good thing....stay far away from the person who is on every page. Sorry husband dear!
