Anti-fairy Pregnancy is the total opposite of Fairy pregnancy, in which it is the males that give birth to the babies. In Anti-fairy pregnancy, it is the females that have the babies just like in human pregnancy. It takes 40 days for an Anti-fairy to have a baby. Unlike Fairy pregnancy, it painless for the mother.
There are five stages in Anti-fairy pregnancy that a female Anti-Fairy must go through before giving birth.
The female Anti-fairy will have strange cravings for objects that don't taste good (such as doorknobs or pillows) and will eat as much as a pregnant dog.
The female Anti-fairy, like all pregnant species, will go through mood swings.
The female Anti-fairy's stomach will bonk her face, smack the floor and bounce the mother around as the baby develops, meaning that the baby is turning upside down and wildly kicking inside her uterus.
The female Anti-fairy will throw up living butterflies, in contrast to the grape jelly that Fairies throw up.
When it has been 40 days and, the female Anti-fairy's belly will inflate like a balloon until it
explodes in a large cloud of smoke, resulting in the birth of the baby. During labor, the Anti-fairy feels no pain and actually enjoys the experience and her stomach will turn back to normal after popping, and because Anti-fairies do not have godchildren, the baby is born naturally (without magical assistance). The labor is faster than humans', Anti-Fairies don't need to go to a hospital, like regular fairies.
