Heidi had some good places to start. One thought I had, did you and your husband have an argument about something that you thought she didn't hear but maybe she did? Like you thought she was asleep or far enough away, but she wasn't. Kids pick up on all kinds of stuff. Is it possible that is bothering her? Can you find a time to talk to her alone to see what this is about? Or maybe your husband can talk to her. He'll have to work hard to not take it personally and focus on what's going on that's making her feel that way.
