Plans for the future

I started thinking today on Jeremy and mine's future. So far the plan is finish school, Find work and move to (hopefully) a semi-permanent location (at least a year would make me happy...we have moved 4 times the year we have been married).
I am planning on becoming a stay-at-home mom so I thought of all the things I want for my children. Then I thought of their entertainment and all the movies I want to get. Then I thought of all that are available now and what will be available in the future. I was thinking of the wonderful technology there is in this world...how things look so much more life like than even 10 years ago. I absolutely love 'The Incredibles', 'Finding Nemo', 'Ice Age', 'Monsters, Inc', etc. but then I thought of all the movies/tv shows I have seen recently that are...well questionable to what I want my child to watch.
For example, I really like Shrek...I laughed fairly hard at more than one part, yet I don't want my child when he is 4 or 6 to see somethings that were heavily suggested in that movie...I don't want him/her to find humor in some of the things they say.
I know I can keep that stuff out of my home but it doesn't mean it won't be available elsewhere. At the same time there are movies that I have watched recently that when I was younger I did not noticed many of things that I caught this time around.

Anyways what that little rant (or thought process) took me to was why is it that the things our children watched become more adult? I was thinking why are all these movies aimed at our kids that have content a child wouldn't even understand?
I came to this conclusion. It is a seed that is being planted. If our children are seeing this situation, hearing these words, and finding it acceptable how can they not feel that way as the grow up? Now I am not saying every movie/tv show is evil. I listed above some of the movies I like and if I watched little kids TV show I could probably find some I liked as well.
As quoted by Thomas S. Monson in "Teaching our Children", Dr. Glenn Doman stated, “What is placed in the child’s brain during the first six years of life is probably there to stay. … If you put misinformation into his brain during [this period], it is extremely difficult to erase it.” In the same talk, Monson says, "Children learn through gentle direction and persuasive teaching. They search for models to imitate, knowledge to acquire, things to do, and teachers to please."
So my goal when I begin to have children is to do my best. I am sure it won't be perfect. I can guarantee it. But I just hope and pray for guidance that I can discern the 'wolf in sheep clothing' in all things that are introduced into our lives.
