A couple welcomed a set of twins just over a year after welcoming their first twins.
Britney and Frankie Alba have gone from a family of two to a family of six in just over two years, with Britney discovering she was pregnant again just six months after giving birth to identical brothers Levi and Luka.
She then gave birth to Lydia and Lynlee, who are monoamniotic-monochorionic twins, also known as “MoMo” twins - meaning they shared the same placenta and amitotic sac in the womb.
The rare pregnancy is high-risk and has an occurrence of only 1 in 35,000 to 1 in 60,000 pregnancies in the US.
Britney Alba, from Alabama, spent 50 days in the hospital with her husband traveling between Tuscaloosa and Birmingham, so they could spend time together and with their boys.
She said: “Concern set in. We realized it wasn’t just another set of twins, but a high-risk pregnancy."
At 24 weeks, MoMo twins develop a risk for cord entanglement that can result in a stillbirth. Because of this, Britney Alba was checked into the hospital at 24 weeks pregnant so doctors could monitor the twins.
Britney Alba delivered the girls by C-section and following time in the NICU, the girls are now home with their mom, dad and brothers, reports Fox19.
Britney added: "After all that time in the hospital, it didn’t seem real, like it was actually going to happen. And then when it actually happened and we were all home, it was surreal."
Frankie added: "It was definitely a very challenging time in our lives and in our marriage, but it was definitely worth it.
“We love it, we love the time with our family, and we cherish every moment."
While MoMo twins carry a higher risk of complications, such as miscarriage, stillbirth, fetal anomalies than identical twins, but also have a risk of cord entanglement.
