Your little one is coming forward because she is the one who is afraid of the sound and she holds the scary memory. I think that maybe she is coming forward because you are growing stronger. When I switch to a protector it is because a little one is too scared to be in front. Maybe she trusts you and your system enough to allow her feelings to be felt instead of hiding behind a protector. As I grow, this is happening to me more often. I am feeling LOTS more fear and shame that was held away from me for years. It is really hard, but I know it is a good sign...
