We're going away tomorrow on a 3 hour drive. I have a zafira and 3 kids and will need 1 seat down in the boot. So how do you normally decide which child has the back seat? Obviously the back seat will take the brunt of a rear collision (touch wood) but i dont want to think of putting either of my girls at a higher risk than the others. The middle seats only have a lapbelt in the middle so thats a no go, and Dp cannot fit between the 2 middle seats (and is quite tall so couldnt really sit in the boot. Am i thinking about this too much? Would you put the oldest in (in my case 7 year old)?
