Don't feel silly. I feel that way all the time when my kids act "different." Remember my youngest staying up the other night (I think you posted on my topic)? And it turned out to be nothing? If it weren't for the relief I feel when I realize they are fine, I would feel so awful and mad at myself for losing so much sleep!
In fact, right now as I type this I heard one of the kids cough in their sleep and a also heard a funny noise and got that shooting terror feeling in my chest only to realize the cough was just a cough and the funny noise was my hubby fumbling with the bedside lamp to turn it off back in our bedroom.
