This is the ‘worst’ birth date of the year, say pregnant moms: ‘It’s too stressful’

They’d rather Santa be the only one making special deliveries during the holidays.

Getting naughty in late March may bring about a not-so-nice surprise for the expecting moms who’ve deemed Christmas “the worst” birthday date for kids.

“The results are in, and 40% of moms shared that the worst of the worst birthdays is December 25,” revealed study authors from WhatToExpect.com, a virtual pregnancy and parenting hub.

“There’s a lot going on at Christmastime,” continued the experts, “and many moms in the What to Expect community have expressed their grievances about late December birthdays, in general.”

Give them a lump of coal — just not a bundle of joy.

But mommies-to-be aren’t grumpy Grinches.

Instead, they — much like everyone else — are merely burned out by the holidays, and can’t imagine adding childbirth to their already lengthy to-do lists.

In fact, a staggering 89% of US adults are stricken with stress during what’s supposed to be the most wonderful time of the year, per a recent report via the American Psychological Association.

To sidestep some of the Yuletide trauma, parenting pros have advised moms and dads against overwhelming themselves with taxing tasks and putting their personal needs last.

So, ladies with little buns in the oven are now willing to serve them up at the first possible opportunity, per WhatToExpect.

The researchers, who surveyed over 400 women, determined that a quarter, or 25%, of expecting moms are open to having an induction or an invasive C-section in order to avoid giving birth on Christmas.

But when asked if they’d schedule their deliveries before or after Santa’s big day, respondents were divided.

“Before,” argued an anxious soon-to-be mommy. “After the holidays, everyone’s exhausted. I am getting induced week 39, and [I’m] going to [choose] the soonest date as my due date is literally Christmas Day.”

“I would pick after if I could,” said another mama-in-the-making. “Everyone is so busy and stressed the week before Christmas.”

But Xmas time isn’t the only day getting a big “X” on the calendar from pregnant moms.

February 29, or Leap Day, as well as New Year’s Day, Halloween, the anniversary of a loved one’s death and a sibling’s birthday also ranked high on the list of worst birth dates.

The findings echo Bo McCready’s chart of the least common birthdays in the US.

The Texas-based business developer crunched Social Security Administration data to determine that Christmas Day, New Year’s Day, Christmas Eve — and even the 4th of July —  are the rarest birthday dates across the nation.

“I also thought it was really interesting Sept. 11 seems to be lower than the other days around it,” McCready previously told The Post.

According to his analysis, summertime birthdays are much more common amongst folks from sea to shining sea.

“When we look at births peaking in late summer,” said McCready, “we can back up nine months and infer that conception is most common around the holidays, when days are the shortest and coldest.”
