The Wicca Book of Days for May 4th
If you are the parent of a baby or young child, keep your offspring close to your side today, for human children are in particular danger of being snatched by fairies and spirited away to fairyland on May 4, according to Irish folk belief. You may not notice the abduction at first, for the “little people” may substitute a changeling for your baby, but as the days and months progress, you may develop an uneasy sense that your infant is not developing as he or she should. The telltale signs of a changeling child include a foul temper, wizened features, and withered limbs.
Whether or not you have a child, the fairies may still wreak havoc through sheer maliciousness. If you consider yourself or your home to be at risk, wearing your cardigan coat, or jacket inside out and leaving a placatory cup of tea and a cake on your doorstep should ensure that you are left alone.
