Rose Quartz is especially good for soothing babies. Keep a piece near their cot or bed at night or at other sleeping times.
It makes for a powerful gridding crystal too. Place a piece at each corner of your property and if possible a piece in the middle and you will be amazed at the difference in energy you will feel. Rose Quartz forms mostly in massive (rock-like) form, but on rare occasion you can get it in crystalline form, which is superb for focused meditation and elixirs.
