The initial trial found a dextrose gel applied an hour after birth resulted in a 20 per cent reduction in the number of babies that developed hypoglycaemia within 48 hours.
Mother Amanda Kamai took part in the study with both of her sons, three-year-old Xavier, and six-month-old Tobias. Ms Kamani, who has type 1 diabetes and has worked in a neonatal intensive care unit, said she "leapt" at the opportunity.
"I was really keen," she said. "It has the potential to make such a huge difference for so many babies and their families," she said.
"Even though it might sound scary - 'we're experimenting on you' - it's only a little bit of gel, all the blood sugar testing they would do anyway. And you still get to be the mum and do all the mum things first."
Researcher Dr Jane Alsweiler, senior lecturer at University of Auckland Medical School and paediatrician at Auckland Hospital, said the team was "very excited" about the results.
"Using dextrose gel to prevent low blood sugars has the potential to stop babies being separated from their mothers in hospital and to improve their long-term development, without any disruption of breast feeding.
"There was also a trend towards fewer babies needing to go to NICU for hypoglycaemia," she says.
These results were from the initial trial. The main trial was now underway.
