I am not personally concerned about independence. I think kids become comfortable in being independent by being allowed to step into independence when they want to and being secure in the fact that it was their choice and that I was there for them while they were independent. So far, I have two pretty independent kids. I started transitioning my older one to her own room at 3, but really she was in my room on and off till she was 7. I did leave it up to her.
I'm not sure how I feel about having postpubescent kids in a family bed. I guess it depends on whether beds seem inherently sexual to you, but I guess I'd question that. They're primarily for sleep. But that seems more potentially controversial anyway.
What about a teen, or college aged kid?
What do you think?
