The full development process for a full grown baby is in approximately nine months. During the different stages of development most people start comparing the size of the unborn baby to different fruit or vegetables. Within twenty-four hours after fertilization the egg can become a zygote and from there a blastocyst, to embryo, and finally to a fetus.
