It is essential for safety that babies travel in a car seat. However, it is recommended that you avoid travelling in cars with pre-term and young babies for long distances. Research into the link between car seats and SIDS found young babies may be at risk of breathing difficulties if they travel while sitting in an upright position for too long.
There is no published evidence that states how long babies should stay in a car seat when travelling. However, infant healthcare professionals, safety experts and most car manufacturers recommend that babies should not be in a car seat for longer than 2 hours at a time and they should be taken out frequently.
If your trip involves driving for long periods of time, you should stop for regular breaks. This will allow you to check on your baby, take them out of the car seat and let them stretch and move around.
Ideally, a second adult should travel in the back of the car with your baby, or if travelling alone use a mirror to keep an eye on your baby.
If your baby changes their position and slumps forward, then you should immediately stop, take them out of the car seat and sit them upright before continuing your journey.
