Attention new moms: contrary to common belief, you can in fact get pregnant while breastfeeding.

New mother Eliza Curby is currently experiencing that reality.

She and her husband Ben welcomed a baby boy named Charlie in January. Eleven months later, she gave birth to identical twin boys, Jack and Wolfe. (Again, a PSA: Don't think you can stop birth control just because you've just given birth. You can't.)

You might have heard this phenomenon—the two pregnancies in one year thing—referred to as "Irish twins". You also might have heard it sounds straight-up exhausting.

Curby tells News.com.au that when she felt fatigued shortly after having Charlie, everyone around her said it was just the whirlwind of new motherhood.

But she knew it was something else entirely.

"I remember looking at Ben and saying, 'I think I’m pregnant.' He just laughed. And over the course of about two weeks it took four tests to get the verdict—I was pregnant."

The news was overwhelming, of course. But Curby and her husband were also excited to be expanding their family—Curby a bit more so, perhaps.

"We were over the moon at the thought of creating our own little family. I say little as Ben’s idea of a family included two children—very nuclear indeed—I, on the other hand have always been set on having as many children as I can."

Curby recognizes how fortunate she is to have had healthy pregnancies and straightforward births. While she gained considerable weight (obviously, since her body was accommodating three new lives over the course of one year), she maintained good health and all of her children had problem-free births.

"I was so scared but secretly super excited," she says of finding out the news of her second pregnancy. "I think everyone has a secret desire for identical twins."

The couple have had to make adjustments, of course. For example, they traded in their car for a Volkswagen van to accommodate the three car seats they now need to travel with at all times.

Curby has been writing about their experiences in a blog called Twingenuity, documenting the excitement and exhaustion of raising young three children at once.

Her exhaustion-induced anecdotes are ones every tired mother can relate to: Being so tired she washed her hair with face wash, pumping without attaching the bottles, and leaving behind a child at daycare (whom her husband had to go back and retrieve).

But at the end of the day, Curby recognizes and appreciates the joy her children bring her, despite the inevitable stress, and of course, the lack of sleep.
