Many gypsies feel that a large family is a happy family, and therefore they like to have lots of children. In order to bring this about, there are a number of magickal workings found in different Romani tribes.
One such rite involves the drinking of a glass of water and brandy mixed with the herb comfrey. The water and brandy is mixed half and half. A good pinch of the powdered rootstock of comfrey is sprinkled on it. Both husband and wife must drink from the same glass, the wife drinking first. Immediately after drinking they must make love. This should be repeated three nights in a row to ensure that the wife will not only become pregnant, but will continue to conceive on a regular basis.
Another ritual also involves brandy. This time, however, the brandy is sprinkled on the bed linen and in a circle around the bed before the husband and wife make love. Also sprinkled around the bed (but not on the bed linen) is coal dust and French chalk. This, too, should be done on three successive nights. The sprinkling around the bed is done in a clockwise direction.
Another spell to ensure that the home will be filled with children is performed on the birth of the firstborn. The baby is brought into the home and laid down first on the threshold, then on the hearth, and then in each and every corner of every room. When it is laid down, the father must sprinkle crumbs of crumb around it and ask the gods for "wealth of life."
