The couple live in Morecambe, Lancs, with their 21 kids and had said their last child, born in 2018, would be their last.

"So now you know guys - we're having a baby," said Sue.

"We're just coming up to 15 weeks pregnant and we'll be able to find out the gender of the baby soon."

Sue said she's due to give birth in April but and said she'd like a boy this time after she had a girl last time.

"I wonder if it will be 11 of each - I am feeling a bit boy," said an excited Sue.

Sue and Noel receive no benefits and keep finances afloat through a successful family-owned bakery.

They claim just £170 a week in child benefit.

The family live in a 10-bed home which they bought for £240,000 in 2004.

Noel had a vasectomy during Sue’s ninth pregnancy but he had it reversed when the couple longed for more children.

Last November the Radfords welcomed baby Bonnie Raye into the family.

She said of giving birth: “She was very quick, she was not hanging around. I think they’ve got my labour down to 12 minutes.”

Eldest kids Chris and Sophie have moved out but all the others are still at home.

The couple are also grandparents to Sophie’s three children. Their supermarket trips cost £250 a week and they have outgrown their 15-seater minivan.

Each day the family consumes 18 pints of milk, three litres of juice and eat three boxes of cereal at breakfast.

And last Christmas, they tucked into three turkeys, 3.5 kilos of potatoes, 56 Yorkshire puddings and massive supply of vegetables.

Sue says family holidays are a "military operation" with the clothes all put into labelled bin bags for each of the children.

Sue recently said with 15 kids at school age or below, one of the biggest challenges is keeping track of the young ones.

"It can be quite hard to keep track of them. You have to eyes in the back of your head to make sure you don’t lose any children," she said.

"The older ones are quite good at helping out with the younger ones, we’ve never lost any yet so we’re doing alright I think. They don’t tend to wander off, they’re pretty good."
