Our family likes old movies, The Marx Brothers, Bob Hope and Bing Crosby, Burns and Allen, and great classics like The Great Race, Paint Your Wagon and Fiddler on the Roof. Throughout our children's lives it has not been kids movies that were different from our movies. We love Disney movies. In fact we just finished the Jungle Book. Our children have grown up with the same tastes in music and movies as we have. We share things together and make it fun and interesting. From talking with parents I find that many send their kids to other rooms to watch things on their own. Parents have different standards for their entertainment.
Many years ago I had a parent who was having a problem with her 5 year old and swearing. She remarked that she was going to come see me earlier in the day but her son was having a birthday party and the movie had not ended yet. The movie she had gotten for him and all of his friends to see was rated "R." Surprise that her son believed that adults swear when kids are not around. It was interesting to find that the 5 year old had seem more R-rated movies than I had.
Be interested in your children's interests and share your interests with them.
