Any mummies use baby carrier instead of car seat when travelling in the car? I know it's not allowed but what happens why say your Friend comes to pick you up, and the baby seat is in your husband's car?

It is against the law, as long as you are not on a public transport. There is grab family and also, recently launched, uber carseat. Although it is rare to see traffic police on the road, do you really want to take that risk?
