Alexis Brett from Aberdeen gave birth to her first daughter, Cameron, with husband David Brett on August 27.
The couple were so convinced that they would have another boy, they didn’t ask the sonographer what their unborn baby’s gender was - but her arrival left them “delighted”.
"We're over the moon,” Alexis Brett, who is an only child, revealed. “I'd been expecting to hear we were having another boy. But when I found out it was a girl, my face was a picture.
“I was shocked, but delighted. Now she's here with us, it's a fantastic feeling,” the 39-year-old added.
Their sons are aged between two-years-old and 17.
With the addition of a newborn, their family is now complete.
Although Brett, who has spent more than eight of the past 18 months pregnant, wasn’t holding out for a daughter.
“I'd never planned to have a large family, but now I do, I love it," she said. “I always joked I wouldn't have a clue what to do with a girl... that's all changed. We're having a lot of fun buying pink things for the first time.”
But their large family has sparked widespread controversy, as Brett admitted that the couple have been judged in the past.
“Of course, we do get comments about the number of children we have - especially when I was pregnant again,” she said. “But it doesn't bother me what people think, we're well used to it.”
“Some people think we must be on benefits, but we're not. David has a good job, which means we don't even qualify for full child benefit.”
In fact, the mother-of-eleven is already planning her return to work as a part-time fitness instructor.
Thankfully, their children - which includes Campbell, 17, Harrison, 16, Corey, 14, Lachlan, 11, Brodie, nine, Brahn, eight, Hunter, six, Mack, five, Blake, three, and Rothagaidh, two - have been helping out around the house after the arrival of baby Cameron.
“They've generally been much better behaved around her, trying to keep quiet in case they wake her up,” their 44-year-old dad, David, revealed. “They also want to help with holding and feeding her - it's been great.”
On a typical day, Brett will kick-start the morning at 5.30am which gives her chance to prepare with a coffee and shower before her sons wake up.
With a full house, Alexis claims to do 49 loads of laundry a week while she gets the hoover out seven times a day on average.
“David and I sometimes look at each other to say, 'What have we done?' But when the boys come out with something funny and make us laugh, it makes it all worthwhile,” she said.
