As a first-time mother, Sara Herman thought it was only to be expected that she had an enormous bump after five months.
What she and doctors failed to realise was that the petite mother-to-be, who is only just over 5ft, was expecting a giant.
When Jack eventually arrived at 37 weeks he weighed an astonishing 14lb 8oz.
And now, after health problems kept him in hospital for four months, he is enjoying life at home in Manchester with 37-year-old Mrs Herman and her husband Keith.
"At five months I looked like I was going to give birth at any moment and the size of my bump meant it was difficult for me to get around," said Mrs Herman, a product sourcer.
"But because it was the first time I'd been pregnant, I just thought this was normal."
A scan at 14 weeks showed the baby was growing fast and doctors even thought that the due date was wrong as the baby was so large.
Jack had grown so big because of a condition called hyperinsulism
At the age of 14 weeks he had 95 per cent of his pancreas removed
