Yvonne Epps and her partner, 21-year-old Jayden, are due to welcome quadruplets in April. At their first scan last September, the young couple were told they were expecting twins.

A month later, doctors discovered that there were two babies in each of the sacs, meaning she was pregnant with two sets of identical twins. The chance of such a pregnancy is about 1 in 70 million, according to AL.com. Epps scheduled a caesarean section for April and the couple is trying to prepare as much as possible.
