"Useful reminders were sent such as do something special as a couple before the baby is born, as well information on how mum might be feeling at different points.
"Once the baby was born, messages came through with information on how to keep the baby safe and healthy."
Northern Sydney Local Health District’s Director of Child, Youth and Family Associate Professor Elisabeth Murphy, said the service is all about helping dads to feel confident and supported in their role as a parent.
"Often dads are really busy before and after the birth and attending parenting classes can be tricky," she said.
"A subtle stream of tips, information and links to services via mobile phone is proving really useful and a supportive resource for dads."
Men living in Northern Sydney can sign up if they are over the age of 18, their partner is at least 16 weeks pregnant or their baby is younger than six months.
The pilot, which is being delivered by the University of Newcastle in partnership with NSW Health, will run over the next year.
