Despite the naysayers, she was able to carry Nathan to 34 weeks before giving birth by caesarean section.
The hardest part of her pregnancy was the attitudes of others, including one non-local doctor who told her: "People like you shouldn't be pregnant."
"I just burst into tears," she said.
"I was 20 weeks pregnant with him and we'd just had the 20-week scan, and he was perfectly fine."
Mrs Teki-Reu said she'd had one miscarriage before Nathan, and the doctor told her it "should have been a sign you shouldn't be pregnant".
"He goes to me, 'How long do you think you're going to last in this pregnancy?'," said Mrs Teki-Reu, who believed she could last until 34 weeks.
"He literally looked at me, laughed at me, and said 'You'd be kidding yourself if you get to 34 weeks'.
"I thought, bugger you, I'm going to prove you wrong'."
Mrs Teki-Reu said she did a lot of research before getting pregnant with Nathan, and was told by friends not to try, otherwise she would be putting her family through turmoil.
"At the end of the day I can't live my life for them. I've got to live my life for me, and I wanted to be a mother."
Adoption and surrogacy were considered, but Mrs Teki-Reu was doubtful people would allow a woman in a wheelchair to adopt a child.
Day-to-day life wasn't particularly difficult for her, despite her truck-driver husband being away often.
"You just cope with what you've got. To me, I just live my life. I don't see myself as disabled."
Mrs Teki-Reu said her local obstetrician was a big support when she was pregnant with Nathan.
"He just turned around and said, 'I don't see why you can't have this baby'," she said.
"It only takes one person to believe in you to make your dreams come true."
Mrs Teki-Reu said her father always told her she could do anything she put her mind to, though she did think he was "going to have a heart attack" when she told him she was having a baby.
She felt the biggest thing people needed to know was that the only disability that needed fixing was a bad attitude.
"That's the biggest disability out there," she said.
