I need to hire a van to collect some furniture from my cousin's house and need to be able to transport my little one with me. He's 4 months old and is in a rear-facing car seat but all the van hire companies I've contacted don't have vans in which the passenger airbag can be disabled. Am I right in thinking that it's very dangerous to have a rear facing car seat in the front if the airbag is still active? Has anyone else had this problem and if so, what did you do?
