It is completely reasonable when one knows why this happened. First of all we choose our parents prior to being born and the reasons are many including making up kharma. When a spirit is in such a rush to enter the earthly plane sometimes they fail to check the physical make up of the embryo and it happens that a female spirit may enter a male body and vica versa. It is truly a shame that so little is known concerning the true nature of the Spiritual side of life and how ti connects to this side of the veil. Usually there is only one spirit per embryo but sometimes there can be several and each must state their case to be able to enter the body of the nearly born child.
