Doctors were so sure that Amber was going to give birth to a secret twin given the size of her baby bump, however, doctors as well the young parents were in for a big surprise as Amber birth to not only a healthy baby girl but the child is believed to be the second biggest baby girl born in the UK.
A British mom has given birth to an infant who is believed to be the second biggest baby girl born in the UK weighing an astonishing 12lb 14oz.
When Amber Cumberland was pregnant, her baby bump was so huge that her doctors were sure that the mom is carrying twins.
However, the mystery was solved when mom finally gave birth to her 12lb 4oz daughter on 16 April, with Emilia thought to be the second biggest baby girl in the UK - after a record-breaking baby born in 2012, who weighed 14lb 4oz.
Mom, from Aston in Oxfordshire, said: "Doctors thought it was twins during pregnancy because she was so big, even though we could only see one on the ultrasounds.
"We heard it so much we actually started to believe there was another one hiding in there.
"It became a game when we went to the supermarket to see if we would get a comment about the size of the bump and we always did.
"When she came out, Scott's face was white and all the surgeons were looking at each other in shock and laughing - they brought her to me and said, 'Congratulations, you've had a toddler.'
"We were just so glad it was only one baby and that she was healthy."
When doctors took her ultrasound, Emilia reached the average size of a 36-week baby by her 32-week scan and was estimated at 8lb 12oz on an extra growth scan at 36 weeks.
Emilia was almost two weeks overdue when Amber was induced, spending 24 hours in labour until she was born via emergency C-section.
Twenty-two-year-old Scott Joy - who is Amber's partner and Emilia's dad - wasn't allowed to join until she was in active labour, meaning the dad spent a total of 42 hours in the car park at John Radcliffe Hospital over three days leading up to the birth.
Amber said: "I got to eight centimetres dilated and she couldn't go any further - if she went any further down they wouldn't be able to get her back up and she would've got stuck.
"During the C-section, it took two people to lift her out and one to hold everything back to get her out.
"The whole outfit we brought didn't fit her but luckily we had some spare 0-3 month clothes packed and the hospital staff had to hunt down bigger nappies from paediatrics for us.
"Nurses at the hospital even stayed over time to see the weight of the baby and take photos with her because she was so big."
Amber continued: "The bump was so big I got lots of stretch marks and my skin was so weak from being stretched out that they would bleed if I stood up too quickly.
"My stomach muscles completely split to the point where the doctors could barely distinguish them during the C-section and said they were the worst they'd ever seen.
"I also had awful sciatica and compressed nerves in my hips and legs because of the weight of her and I couldn't even roll over in bed without Scott to help me."
Just over a week after giving birth, Amber is starting to heal, but expects the full recovery to take a while.
"I'm still as uncomfortable as when I was pregnant but I do feel a lot lighter and have no more trapped nerves which I'm very grateful for," she said.
"We're both so overjoyed with our gorgeous little girl."
