I have seen a lot of advertising for the Safesnug Hammock & was wondering if it’s a safe option. They say it is shaped like the womb & cradles the baby to prevent rolling. it has been certified by CPSC & are using them in daycares. Has anyone looked into this product?

Red Nose recommends that the safest place for baby to sleep is in a cot that meets mandatory Australian Standards.
The mattress should be firm, clean, well-fitting & flat (not elevated)
One safety concern with the hammock is that it holds the baby in a curved position, this may cause baby’s neck to flex forward which may block baby’s airway not allowing airflow.
A baby needs to be placed to sleep flat (not elevated or curved with chin on chest) to maintain an open airway
There is also a risk of injury or death from falls.

It is a normal development stage for babies to roll
As babies grow and develop they become very active and learn to roll around the cot.
At this time, continue to put them on the back at the start of sleep time, but let them find their own position of comfort.
By this stage it is not necessary to wake during the night to turn baby over to the back position
