Mum Britni Church, who posts on the video sharing app as @ourlargefamilylife, opened up about how she expanded her family over the years.
She shared a short video with her 1.8 million followers to explain her age at the time she gave birth to each child, and the video has been viewed more than 434,000 times since it was posted on 28 May.
Under the three headings 'teens', '20s' and '30s', Britni included a list of how old she was each time she gave birth.
In the final column, she revealed she gave birth to triplets at the age of 30, however this part of the video left some viewers confused.
One person quizzed: “I'm genuinely so confused in the 30s.”
Another commenter wrote: “Not me thinking it was impossible to have 3 at the same age.”
However one fan quickly replied: “It was triplets. We follow her. They're cute as all heck, as are all of her kids. 2 of the 3 look identical.”
Another woman replied: “She had triplets when she was 30 to everyone that might be confused.”
Her twelfth child was born when she was 32.
The video was met with a kind response from TikTok commenters, who praised the mum-of-12 for raising a large family.
“I salute you,” one woman replied.
One sports fan pointed out: “That’s a whole basketball team.”
Someone else replied: “That’s a football team.”
A third typed: “Your house would definitely not be boring. How awesome, very happy for you.”
Elsewhere, one mother from TikTok was left horrified after checking on her daughter through a baby monitor, only to be met with a rather chilling image.
Christie George was expecting to see an adorable image of her daughter fast asleep when she picked up her baby cam, but was instead met with a surprise.
TikTok users took to the comments after watching Christie's surprising video to discuss the terrifying sight on her monitor.
"This is why I hate putting my son in his crib in his room," commented one TikToker. "Bc that means I'll have to check the monitor and I'm scared of this. idk why."
Another wrote: "That’s why I refuse to have a camera monitor."
Shocked is an understatement!
