Mum shares mesmerising side-by-side videos of her pregnancy with twins versus one baby.

Vlogger Natalie Bennett is currently 36 weeks pregnant with a baby girl. She’s also a mother to twin boy toddlers.

Despite her probably extremely hectic life, Natalie has been regularly sharing pregnancy updates via her YouTube channel, and this week’s update was very special indeed.

You see, Natalie decided to share the comparison between the size of her baby belly while she was 36 weeks pregnant with twins, and her belly now, with just one baby inside.

The results are eye-watering and mesmerising, to say the least.

A gif of Natalie's two bellies, side by side, has since been viewed more than 282,000 times on picture sharing site Imgur.

The soon to be mum-of-three is the first to admit that her first pregnancy belly "looks inhuman".

"My belly was so ridiculously large," she said of the comparison between her two pregnancies.

"People look at it and go, 'Oh my gosh, what the heck am I looking at?' But that is actually what I looked like.

LISTEN to the latest episode of pregnancy podcast HELLO BUMP, where Bec Judd and Monique Bowley talk baby brain and shotgunning names.

"I had a huge torpedo belly sticking out...like a shelf, it was so heavy and my skin was so stretched."

Just a few weeks shy of welcoming her third child, Natalie said life as a mother is "as hard as it's ever been".

"Parenting toddler twins is hard, and I'm nine months pregnant," she said.

"I'm exhausted by the end of the day, I'm discouraged on a regular basis because we're in the terrible twos with these boys and it is a lot of work.

Happy #StPatricksDay from my little leprechauns!!! These guys are 1/4 #irish on their Daddy's side! #thewearinofthegreen

"It's a lot of work to be pregnant and to be doing this at the same time."

Overall, Natalie said her second pregnancy has been "easier" and "much more comfortable" than her first.

"I would say that this pregnancy just overall has been more convenient because it has been so straightforward," she shared.

"One baby is so much more straightforward than a pregnancy with multiples."
