Valentine’s day brought a very special delivery to Tressa and Manuel Montalvo of Houston: two sets of identical twins.
The quadruplets were conceived spontaneously, without the help of any fertility treatments or drugs – something that has a one in 70 million chance of happening, the hospital says. They were born at 31 weeks by Cesarean section to Tressa, who is 36, The Woman's Hospital of Texas
in Houston says.
The couple had been trying for one brother or sister to keep their little boy Memphis, now 2 years old, company. At 10 weeks, they learned she was having twins. But when the couple went in for Tressa’s 12 week check-up, they learned she was carrying not two, but four babies.
