- Robert and Nia Tolbert had their first child six years ago
- They welcomed twins about three years later
- They are now expecting triplets
A couple in Maryland, US is set to welcome triplets into the world after first having one baby followed by twins.
Robert and Nia Tolbert welcomed their first son Shai six years ago. They then got married in August 2014, around the same time they welcomed twin boys, Riley and Alexander.
During her ultrasound recently, Nic discovered that she's expecting triplets. Dr. Rami Tabbarah, an expert at Inova Women's Hospital, said this phenomenon is rare.
It's extremely rare. We're talking less than one in 1,000 (births). That's a very low chance for it happening to anyone in general. It's very rare to have twins then triplets (naturally) in the same lifetime.
Robert said he was equally surprised:
We joked about having a big family, but we never thought it would happen to us. We thought we were good with one or two, but here we are.
The three bundles of joy, who are all girls, are expected to arrive in March 2018. The couple expressed joy that after having three boy, they will now have three girls.
Dr. Rami explained that this phenomenon happens when a woman hyper-ovulates, which is a rare occurrence when more than one egg ovulates at once.
