My baby (9months) fell onto the edge of the skirting board nearly a month ago and she cried a lot. There was a small horizontal bruise that lasted 2 days. Today, when taking photos, I noticed that she has a dented line on her forehead when she raises her eyebrows. I never noticed it before as she has a fringe. I feel awful and so upset about it. I have read that forehead dents are here to stay. Has it happened to anyone else before? Does massaging the area help? Is it really permanent? Thanks
