A couple out of Ewing Township has done the near-impossible without even trying.

With the birth of their third child early last week, Catherine and Jim Mabee completed an rare delivery room feat.

Their three sons, each born three years apart, came into this world on Jan. 1, Jan. 2 and Jan. 3.

And this definitely wasn't done on purpose, the couple told New Jersey 101.5.

Declan, the oldest son, was due on Jan. 9, 2010, but Catherine's blood pressure issues forced doctors to induce labor on the first of the month. Three years later, Catherine was dilated early with her second son, Connor, who was due on Jan. 10, so doctors moved the schedule up a week once again.

Brothers born on the first and second days of the year are rare enough, but the couple knew they were entering uncharted territory when they heard the due date for their third child — Jan. 3.

"No one believed it would actually happen on the third," Catherine said. "We didn't believe it would happen on the third."

But, despite Jim's hope that the baby would be born in 2015 to provide an extra tax break for the year, child No. 3 was born right on schedule.

"I don't know what the odds are, but I'm sure it's pretty rare," Jim said.

According to data from the Perinatal Institute, a baby is born on its predicted due date just 4 percent of the time. But good luck figuring out the odds of having sons born on three sequential days, in that exact order.

Even young Declan said the scenario is "a lot crazy."

And just to add to the fun, Jim is a January baby as well.

The Mabees said their sons better get used to sharing a birthday party.

"We've got a lot of relatives and family in the area, so we can't really ask them to come over three times for three parties, right after Christmas," Jim said.

When asked if they would ever try for lucky No. 4, both insisted the pattern stops here.
