Figures released under the Official Information Act estimate around 1800 babies are delivered after PPROM diagnoses in New Zealand each year. Most are healthy. Around 25 neonatal deaths were thought to be PPROM-related.
Ava's grandmother, Janine Cornelder, said she wanted the hospital to "step up" and institute policies so women diagnosed with PPROM were given good advice - not just told to terminate.
They also wanted to meet staff at Auckland Hospital where Toni was treated from 26 weeks and where she was advised to terminate at 30 weeks.
PPROM causes the loss of amniotic fluid rich in the protein, carbohydrates, lipids and urea a growing fetus needs to survive.
Waikato Hospital confirmed that it met Alexander and was still working through her concerns.
"We are glad she has a healthy baby and we will continue to work with her," said chief operating officer Jan Adams.
