The difference between the two systems is very important. On one hand, we have the carrycot or bassinet, which is not a child restraint system as such and does not provide the same protection to the child.
The use of a carrycot is only recommended when the baby must travel lying down for medical reasons and if advised by the pediatrician. This may be the case for premature babies who must lie completely flat to ensure, for example, good breathing. We talk about how these children should travel in this article. In this case, the baby travels sideways and the head should be placed towards the center of the vehicle. It is installed with a safety belt and the newborn must also be restrained so that he/she cannot be thrown out of the car seat.
The 'maxicosi' type car seat, i.e. the 'egg' shaped seat, which can belong to groups 0 and 0+, is the most suitable option for transporting newborns, provided they do not have any health problems. They allow children to travel facing backwards (up to 15 months in the R-129 or I-Size CRS) and have reducers that allow the baby to travel as horizontal as possible providing ergonomics and protection.
In all cases and as previously mentioned, it is necessary to consult with your midwife or pediatrician about the safest way to transport the baby, especially if the newborn has a specific condition.
