If you decide to tag along your baby on a travel, it is important to have them in a baby seat. Most parents use front-facing baby seats. However, rear-facing baby seats are considered to be the most safe for a baby in case of a crash.
I think it all depends on the preference of the parent, but if it's really safer to have rear-facing baby seats instead of the front-facing ones, then the parents should just buy that kind instead of the other one so that their baby would be more safe.
