if your 7 yr old daughter wants to, hy not let them share a room. it might just mean alil more giggling at night, but they are both still young, so i don't think there should be a arguing over space problem. but agin, only if your 7 yr old really wants to. my son did not like to sleep in his own room til he was ..15..lol..he would sleep on the couch, just didn't want to sleep in his room. does she watch any scary movies/shows? Its possible, even without the TV, she might just be starting to really realize all the bad things that really go on in the world. talk to her about that stuff, see if she might be afraid of someone breaking in the house, anything like that. Then talk to her about all the things you might do to prevent that. Discuss fire drills with her also, so she has a sence of "i know what to do if this happens now." Good luck.
