New research out today has revealed that New Zealand's stillbirth rate is 10 times higher than the number of cot deaths.
The findings, published in The Lancet, form part of a major study into global stillbirth rates.
Researchers believe that of the 2 million babies stillborn every year worldwide, about half could be saved if mothers had better access to medical care.
Heather Clarke has a son and two daughters, but Danielle will never get to meet her big sister Stephanie - at a routine check up at 33 three weeks, Ms Clarke got the news every expectant mother dreads.
"I knew something was wrong. Everything was taking far too long, nobody was saying anything, and then my midwife just put her hand on my shoulder and said, 'I'm so sorry honey, your baby has died.'
"I can't describe how I felt. Our whole world just fell away."
A global study released today by medical journal The Lancet reveals stillbirth rates in developed countries are frighteningly high. In New Zealand alone, at least one baby is stillborn every day, six out of every 1000 births, and in a third of all cases, the cause is unknown.
There are some risk factors - women aged 35-plus are more vulnerable, as are those who smoke or drink.
Researchers are particularly worried about rising obesity levels.
"Women who are obese have a two-fold risk of having a stillborn baby, and when you consider that 40 percent of us are obese, that problem affects a huge percentage of the population," says Prof Lesley McCowan.
But there isn't always a clear cut answer. The stillbirth rate is being described as the quiet epidemic, and support groups want greater awareness of the problem.
Sarah Numan runs the Manukau branch of Stillbirth and Newborn Death Support (SANDS). She's had three stillbirths herself.
"It is pretty huge. It's double the annual road toll, it's higher than breast cancer deaths, prostate cancer, suicide deaths."
New Zealand researchers agree with global findings that better medical care, particularly early antenatal care, would be a step forward in prevention.
