Looking for advice. My 11 month old was crawling on the bed when she tumbled and hit her forehead on the edge of the wooden footend. Immediately a goose egg bump appeared, she cried, I iced it down, kept an eye on her and all is fine. Fast forward 5 days, the swelling has gone with near enough no bruising on the skin (just a slight yellowing), but now there's a hard line under the skin (maybe even on the bone as when I move her skin it doesn't shift ) from where the impact was. You can see that protruding out on her forehead; has anyone had this experience before? Will this disappear? How long may it take? Tia!
