The wife of San Francisco Giants shortstop Brandon Crawford and her twin sister had doctors at an Arizona hospital seeing double when they both delivered sons on the same day in June.
Jalynne Crawford and Janelle Leopoldo each had a C-section performed by the same doctor just two hours apart.
Bryson Ryder Crawford is Jalynne and Brandon's fourth child: they also have daughters Jayden and Braylyn, and son Braxton.
Jace Alan Leopoldo is Janelle and Jason Leopoldo's second son, who was conceived with the aid of in vitro fertilization.
Both Crawford and Leopoldo had struggled with fertility issues, with the former suffering two miscarriages and the latter losing one baby.
The back-to-back deliveries on June 18 came after an especially tough year for the family: Crawford and Leopoldo's sister Jennifer Dantzscher Pippin died of an asthma attack in April 2017, aged 38, leaving behind a husband and two daughters.
‘We said Jennifer was in heaven and would pick our two babies for us,’ Crawford told Good Morning America.
Around the same time, their other sister Jamie Dantzscher, a former artistic gymnast who was on the bronze-medal-winning team at the 2000 Olympics in Sydney, testified before the US Congress about the sexual abuse committed by USA Gymnastics' national team doctor Larry Nassar, who was later convicted and sentenced to up to 175 years in prison.
