Meet the mum whose video of her family recently went viral on TikTok, with users commenting that she and her children could be mistaken for siblings.

Nina Dixon, 31, said people are stunned when they find out she is the mum of a 15-year-old daughter, Millie, 11-year-old son, Keaton, and 10-month-old baby Harmony.

The student nurse - who had Millie when she was 16 - posted a video with her children on TikTok, with users commenting they could pass as siblings.

Her youthful looks mean she has to take her ID on every night out and has even been asked for identification when trying to buy a hamster.

At parents' evenings she said she’s even been mistaken for one of the pupils.

Nina, a student nurse, from Darwen, said: “People think I’m Millie’s sister all the time and now my son has shot up it’s happening with him too.

“I went to buy a hamster for my son a few years ago and the assistant asked if a parent was with us.

“I laughed it off saying I was their mum, but he persisted to ask me for ID as he didn’t believe me.

“I’ve had to drive back to get my ID for a glue gun before.

“It is frustrating but other times it can be flattering to know I still look young.

“My mum has always looked great for her age, so I think it runs in the family.”

Nina struggled with negative comments after she fell pregnant and had her daughter in May 2007.

“People said that I wouldn't amount to anything,” she said.

“It was hard to hear and stayed with me a long time.”

But Nina took to being a mum and had her second child, Keaton, in February 2011.

Now Nina has a baby girl, Harmony Nelson, with her partner, Jacob Nelson, 27, a business development manager.

“People are always shocked when I say I have a 15 and 11-year-old as they say I look in my early 20s," she said.

“When Keaton was just seven and in year three other parents thought I was a pupil too.

“I think people think I’m young because I’m very petite - I’m a size six, 5ft 1ins and have size two feet.

“I do look like a little girl sometimes.

“When I’m with my mum, Caroline, 68, and the kids, people think we’re all her kids.

“It can be frustrating but mostly I see the positives.”
