A father was shocked when he found out his wife was expecting triplets after welcoming a set of twins.

In addition to the three bundles of joy on the way, Nia and Robert Tolbert of Waldorf, Maryland have three sons, ABC News reports. The couple welcomed one son, Shai, six years ago. Twin boys Riley and Alexander came next. The twins are now two years old.

Nia surprised Robert with the news by placing the sonogram photos in a bag with three onesies.

“I opened the bag and I saw a very, very long sonogram,” Robert told ABC News. “Then I saw three onesies in the bag … and they were numbered 1, 2, and 3.”

The couple told WUSA they babies were conceived naturally. Nia learned she hyperovulates, which means her body releases more than one egg during ovulation.

After getting over the initial shock, they said they are excited to welcome the newest members of their family.

“We live by the mantra of being impeccable with our words. Words have power. The more positivity you speak into your life, the more positivity you’ll get out of it. So we don’t have time to be negative or woe is me or be nervous,” Robert said.

The couple told Inside Edition they’re officially done with having kids. They found out in an exciting gender reveal that they are expecting three baby girls, bringing perfect balance to their home — three boys and three girls.
