Is cocoonababy product a safe sleep product? https://cocoonababy.com.au/

There are some concerns in relation to portable sleep space products like the Cocoonababy for infant sleeping.

Red Nose recommends that the safest place to sleep baby is in a cot that meets the Australian Standards, on a firm, clean, well-fitting & flat mattress.

Many products on the market today do not promote a firm & flat surface.
There is a risk to baby of being placed to sleep in a position that may facilitate baby’s neck being flexed to the “chin on chest” position.
There have been accidents associated with bouncers, rockers and hammocks such as falls and entrapment, but the biggest hazard is the risk of a fatal sleeping accident.
When a baby is put to sleep in one of these devices, their head can roll forward, blocking their airway.

When a baby falls asleep in a propped-up device the head can fall forwards, pushing the chin down towards the chest.
This can lead to the airway becoming blocked and reducing airflow.

Also, portable sleep surfaces, like the one you describe, do not have Mandatory Australian Standards for safe infant sleep.
All safety standards for products in Australia are developed & monitored by ACCC - Product Safety Australia - https://www.productsafety.gov.au/products

Placing a baby for sleep on their back & flat (not elevated), is the safest way for baby.
Baby’s swallowing & arousal mechanisms work more effectively when flat & on the back.
Babies are at risk of “chin on chest” position when not lying flat, which may increase risk of compromising baby’s airway.

Red Nose does not recommend restraining a baby in any one position while sleeping.
