I was wondering if Red nose has a position on travel systems (car capsules that can be used with a pram). Is it better to just use a pram with a bassinet?

As far as sleeping is concerned, Red Nose recommends placing baby for sleep in a cot that meets Mandatory Australian Standards. (AS/NZS:2172)

While bassinets do not have Mandatory Standards in Australia Red Nose & Product Safety Australia (ACCC) do provide information about safety when using a bassinet.
Safety information is based particularly around the stability of bassinets & height of side.

The safest place for baby to sleep is usually in baby’s own safe cot, however, bassinets are increasing in popularity because a safe cot can take up a lot of space, especially for families living in apartments or smaller houses.

But unlike cots, there are no Australian safety standards for bassinets, so it’s important for parents to know what to look out for when choosing and using a bassinet.

Car capsules/car seats are compulsory for use when travelling in a car.
Red Nose does not recommend their use when not travelling in a car.

Once the car journey is over it is very important that you remove baby from the car seat or capsule, even if this means waking baby, because it is not safe for baby to spend long periods in car seats, capsules or infant seats.

Research has shown that:

babies left in a sitting position for a long period of time may be placed at increased risk for sudden infant death.
car or baby seats may cause baby’s neck to flex forward which may block baby’s airway not allowing airflow
falls from car seats used outside of the car as infant carriers are common, often involve children unbuckled in their car seats and represent a significant source of head injury for baby. Never leave baby in carriers on shopping carts, counters, or other high locations

Avoid sleeping children in prams or strollers.
Never have an unharnessed child asleep in a pram or stroller as they can move about and may be at risk of falling or entrapment.
If they are asleep, maintain regular supervision.

Never leave your baby unattended in a pram or stroller. It is not a substitute for a cot.
