We have been given a pram which does not recline all the way flat. Is it still safe to have a new born there? I haven't come across any concrete advise. thanks

It is important to ensure that the pram you have been given meets Mandatory Australian Standards - AS/NZS 2088:2000
Information about the Standards for Prams & Strollers is available to read from Product Safety web site.

Red Nose recommends that a baby be placed on a flat (not elevated) surface for sleep.
While a pram is not a substitute for a cot as a sleep environment, babies will go to sleep when in a pram.
It is still important that baby’s sleep surface in the pram is firm & flat.
If baby is left sleeping in an elevated position it may cause baby’s neck to flex forward (chin on chest position) which may block baby’s airway not allowing airflow.
