My used some colorful language while we were on vacation.

My 4 years old is like a parrot...and whatever she hears she imitates. And this usually comes from the tv. One day, she was telling her 1 year old sister to "shut up"...and never in the house we use that word. So, I calmly ask her what did she say and she repeated it. I asked her where did she hear it and she told me from a tv cartoon. Then I asked her again, "did you hear Mama and Papa saying that to you or your sister or around the house? ". She told me no and she thinks those are new words. I explained to her that whatever she sees or hears on tv doesn't need to be repeated or imitated because those are for entertainment purposes. Aside from explaining, I monitored closely what she is watching and letting her watch more VHS/DVD's rather than live tv. I also cut her tv time and let her do more arts and crafts. I haven't heard her say anything bad or some shocking words.
