The Pepi-Pod provides a small sleeping area for infants up to five months and includes a cover, fitted mattress, sheets and merino blanket.

Mothers participating in the trial - which will focus on Hobart before potentially rolling out statewide - will also take part in a safe sleep education program.

Child Health and Parenting Service nursing director Dominica Kelly said mothers would be offered a pod at a late antenatal appointment.

"In this trial, we're going to be assessing if parents find Pepi-Pods easy to use, does it help them put their children to bed in a safe way, for every sleep occasions, not just evening sleep but during the day," she said.

"It's encouraged the pods are taken wherever the baby is fed, wherever they're settled, to ensure that they have a space that keeps them safe during their sleep.

"We'd be talking to staff about how they communicate to parents, and how that messaging works for both the staff and the parents. We'd be talking to parents who received the pods, about whether or not they found them easy to use and whether or not they felt their child was safe in the pod in their home environment."

Pepi-Pods were devised following the Christchurch earthquake of 2011, when public health officials provided safer sleeping options for babies. It resulted in a reduction in the instances of SUDI.

Health Minister Sarah Courtney said a successful trial would result in the program being rolled out further.

"With any type of trial we need to make sure that we've got the critical mass, but also the people that are conducting the trial need to be together to be able to do that in a clinically appropriate way," she said.

"This is on the advice of the experts that we're rolling it out in this way.

"I'm very hopeful that we'll get the expected results, and should that happen we'll look to be able to roll this out substantially across Tasmania."

Safe sleeping principles for infants include having an age-appropriate separate sleeping area from the parents, an environment that is free of smoke, drugs and alcohol, ensuring the infant's face is not covered, and that they are in a space that is safe from injury related to crushing.
