My DD had a nasty bump this morning and has a big bruise on her forehead. Despite my initial shock (didn't help MIL is staying and kept pointing out how close to her eye it was), and hers, she doesn't seem to be suffering with it. Have applied arnica cream. DH suggested I give her some arnica pillules that we have. Have given her one as I know it won't hurt her, but the lowest strength I have is 30c - should I give her any more or just stick to the cream?
