Family 'home run' with two sets of twins 03:39

One couple in Houston was hoping for a little brother or sister for their two-year-old son. Instead they ended up with FOUR more boys!

In a 1 in a 70 million, chance, Tressa Montalvo was pregnant with two sets of identical twins, without the help of fertility treatments. The four little guys were born on Valentine's day.
Manuel and Tressa Montalvo talk to Soledad on "Starting Point" this morning about the remarkable birth, and Dr. Brian Kirshon explains the rarity of this type of birth.
