When Dayna Allen found out she was pregnant at 19, she knew she needed to cut the cigarettes.
But she didn't.
As a result, her daughter Tayla was hooked up to breathing support just hours after her birth.
Allen tried to quit countless times after Tayla was born, but never managed to lay off the smokes for more than two months.
Until she learnt she was pregnant again.
Now Allen is seven months pregnant and five months smoke-free after a decade of smoking an average of 10 cigarettes a day.
"As soon as I found out I was pregnant, I said I'm not bringing the baby into a smoking house."
Allen stopped smoking through Once and For All, a Waikato and Tairawhiti initiative launched in 2016 and run by Pinnacle Midlands Health Network.
Once and For All uses "quit coaches" - often nurses or doctors - who visit smokers once a week to help them through the quitting process.
