So when people's babies fall asleep on a car journey, do you not bring the car seat in and let them sleep longer? Even if they are positioned well and have the monitor directly on them with no blankets etc?
Do you wake them up after the car journey to get them out?
I didn't realise this was so bad. I don't have a doona but if my little one falls asleep in the car I usually bring her into the house in the car seat. She's 1 now
I wouldn’t leave them unattended (even with a monitor on) and only for a very short time. If a baby stops breathing it will be silent, so not something that will be picked up by a baby monitor. A baby could suffocate/stop breathing in the time a parent turned away for just a couple of minutes. Not saying this to scare monger but this is why it is dangerous and against safe sleeping guidelines.
ETA that obviously putting a baby in a car seat to drive somewhere is necessary and low risk for short times. It’s specifically putting the baby in there to sleep when not driving or leaving them for long periods with a parent distracted/with a baby monitor that increases the risk.
